Transportation sector is the major consumer of oil products. Since consumption of gasoline has increasedduring the recent years, pollution of air and warming up of the earth as result of the production of green housegases, has increased. Natural gas, due to its environment friendliness as one of its characteristics, can becomethe dominant fuel in the transportation sector. In this study, we have evaluated the amount of Green HouseGases produced from transportation sector using Clean Development Mechanism formuala. Then external andsocial costs from produced Green House Gases, the economies of the owner`s and governmental view and thepresent capacity of CNG stations to replace the CNG for other conventional fuels in zanjan city, were studiedaccording to the variety of sceneries (increasing amount of bi-fule vehicles 25%, 50%, 75%, 90%, respectedly).The results show that the most amount of Greenhouse Gasses (GHGs) belong to the vehicles with conventionalpetrol engines which exceeds 2.08×1011 CO2 tonnage in a year imposing external and social costs whichamount to $2.9×1012 and $1.6 ×1012, respectively, in just one single year. The least amount of (GHGs) belongto the CNG fueled vehicles with 3.4×109 CO2 tonnage in a year imposing external and social costs that wouldbe $1×1010 and 1.4 ×1011, respectively, in just one single year. This study implies that the cost is mounting up,in the owner`s and governmental view. The present capacity of CNG stations to replace the CNG for otherconventional fuels is just suited to the existing conditions in this city and the number of bi-fuel vehicles, butin other sceneries which requires that the city must be provided with other stations, should be disused in anindependent study.

In this article, the amount of pollutants and water discharge in Firouzabadi drainage channel wereestimated to be able to simulate the existing and future quality and quantity of the channel, using EPAStorm Water Management Modeling (SWMM). In addition, several best management practices(BMPs) such as; swales and porous pavements were utilized. The goal of using such techniques wereto reduce runoff peak flow and non-point source pollution through evaporation, filtration, andchemical or biological treatments. It is obvious that non of above techniques alone, could not improvethe runoff quality effectively. It sounds wise to combine two or more techniques together to reach theoptimum efficiency in controlling the amount of runoff. In this research, two main models were used:rainfall-runoff model and optimization model. SWMM was applied to simulate quality and quantityof runoff. Nevertheless, Multi Objective Particle Swarm Optimization (MOPSO) was used tooptimize the BMPs layouts so that the peak flow will be minimized effectively. The results show thatin additon to improve the quality of runoff, BMPs can reduce the peak discharge flow between 8 to15 percent for 5-year return period.

Landfill of Rasht has been selected without any site selection process. Pollutants from this site, whichis located near to Siahroud River, are discharged into Anzali Wetland. This research aims to evaluatelandfill of Rasht by current methods for identifying impacts. In this study, landfill site selectingmethods such as Oleckno, Drastic and Monavari method was used and compared together. The resultsshow that this site was classified as a good category in Oleckno Method, moderate in Drastic methodand unacceptable category in Monavari method. Comparing the results shows a heavy variation. Thereasons of this differ in number of parameters and also for the lack of weighting in some methods.Also the results show that considering more parameters in evaluating of landfills can reveal morenegative impacts. This research reveals that, the methods whit both specific weight and abundance ofparameters show more reasonable results.

Widespread impacts of human activities have been the most important environmental issues of thecurrent century that resulted in the loss of major parts of the structures and functions of importantecosystems around the world. This dilemma, clarifies the need to assess and control these destructivetrends. Assessment and monitoring of ecosystem health, means a continuous assessment of overallperformance, including: monitoring of sustainability and stability of the structure, function andprocess of the ecosystem and its resilience after the occurrence of a disturbance or stress. Ecosystemhealth has been recently monitored by establishing quantitative indicators, detecting and monitoringtheir changes over a long period of time. Current research illustrates how ecological problems rangingfrom biodiversity loss to land-use change have benefited greatly from advances in geospatialtechnologies such as GIS and remote sensing, both in the provision of data and access to spatial dataanalysis tools. This research intend to study and suggest a new method for monitoring and assessingthe environmental health by using spatial indicators based on remote sensing and GIS technologies.The result of the study indicates that among the indicators of ecosystem health based on remotelysensed data, land cover maps with suitable temporal resolution and vegetation indices like NDVI andLAI are the most suitable indicators for ecosystem health estimation. This research also suggests theintegration of landscape and biodiversity matrixes as well as non-remote sensing indicators (likecarrying capacity and environmental loads estimation) are to be proposed indicators in order toestimate ecosystem health with more accuracy.

In Bushehr sea waters the coastal organisms such as Razor clam (solen roseomaculatus) are exposedto oil pollutions, because of the industrial and shipping activities, as well as oil production. Polycyclicaromatic hydrocarbons (PAHs) in oil the most important group of hydrocarbons content, which aremarker of oil pollution. Nowadays the bivalve are used in bio monitoring studies, a lot. In order tobio monitor as well as study correlation of PAHs concentration in sediment and S. roseomaculatusinin Bushehr coasts, sampling of sediment and clams were Carried out from five different stations inApril 2009. The samples were homogenized and their PAHs content were measured by GC-MS afterextracted by soxhlet apparatus. Results showed that tPAHs concentration in stations Kalo, Bardkhon,Piazi, Bupatil and Haleh were 63.7, 45.1, 17.4, 172.1 and 28.9 ng g-1 respectively. Concentrations ofPAHs in S.roseomaculatusin from above stations were 490.3, 321.7, 80.2, 759.2 and 111.9 ng g-1respectively. Sediment and clams from Bushehr Khors are partly high contaminated by PAHs. Asignificant correlation was observed between sediment and clams PAHs concentration (P<0.05).S.roseomaculatusin seems to be a good agent for PAHs monitoring in Bushehr province in PersianGulf.

Because of the increasing need to recreational centers in our country, study of ecotourism is a necessity. Severalmethods of evaluating the environmental satisfaction have been introduced. But the efficiency of each methodhas not been much discussed in case-studies. In this research, the recreational value of the district wasdetermined in order to study the satisfaction value of the recreational district "Taleghan dam". So, in the presentstudy, the effective elements of willing to pay in Taleghan dam 's visitors and also the average estimation oftheir willing to pay were determined by contingency valuation method and two-stage Heckman model. Thenecessary data were gathered through filling the questionnaire and verbal interview of 314 visitor in springand summer 2011. The results show that 86 % of under-studt visitors had the willing to pay for recreation.Using the contingency valuation method, the willingness to pay per person per visit was estimated $1. Thevariables of the recommended cost, monthly revenue of family members, educational level, satisfaction rate,nativeness, the willingness to revisit, the seasons of spring and summer, satisfaction level are effectiveelements of the willingness to pay in this method. Also, by means of two-stage Heckman method, the averagerate of the willingness to pay was 1 cent. Monthly revenue, educational level, satisfaction rate, occasions ofvisiting the competitor places of Taleghan dam and satisfaction rate are the effective elements of people 'swillingness to pay in this method. The results show optimized method for determining the recreational valueof Taleghan dam was two-stage Heckman method.

Due to the different factors and complexity of their effects on health and sustainability of urban forest, thisstudy has been tried to determine the effective factors in ecosystem health by dividing Sorkhe Hesar man madeforest park to homogeneous units according to natural factors (slope, aspect, high, soil depth) and humanfactors (amount of irrigation and outdoor recreation intensity). Conifers quality including Pinus eldarica,Cupressus arizonica and Cupressus sempervirens were studied. Evaluation criteria of homogeneous units wereheight, basal area, crown diameter, crown simultaneity, vitality, herbal layer density and canopy density. Inorder to study visitor Impact on soil compactness, soil block density and porosity were measured in both 0-15and 15-30 depth of soil. Analyses of results showed complexity of factors have been affected on site healthand sustainability, while slope and soil depth are the most important limiting factors. In fact with decreasingsoil depth and increasing slope above 15 percent, to intensive recreation usage, would disropt ecosystemintensely. Also, researches showed that in the similar condition Cupressus sempervirens is more sustainablethan Pinus eldarica and Cupressus arizonica.

The importance of Green spaces in urban areas, especially in large industrial cities is an index ofsocial development, which increases the quality of life. Thus distribution of urban green space in acity is very important .This research is more perfect than the study of green space areas because itfocuses on distribution. In this research first maps of parks and border of regions were depicted bydigital atlas of Tehran parks and parks were classified to Neighborhood, district and regional classes,by using of ArcMap and IDRISI software. Then park maps in twenty-two regions of Tehran, by usingthe selected landscape metrics including (CA, NP, PD, PLAND, MPS, LPI, LSI, MNN, Shape-MN,SHDI, MSIDI, SHEI, MSIEI), were resulted. Thus Composition, configuration, expanse andcontinuity of parks were also analyzed by using of Fragstas soft ware. At first twenty-two regions ofTehran were analyzed according to the park classes and then every park was analyzed withoutbelonging to any classes. The regions of one, seventeen, fourteen, twenty one and twenty twoindicated the most amount of the fragmentation, connectivity, diversity, evenness and dominancerespectively. Neighborhood parks in ten and twenty regions had the most amount of dominance andconnectivity respectively. District parks in nineteen region had the most amount of both dominanceand connectivity. Regional parks in fifteen region had the most amount of the connectivity.Neighborhood parks have the best spatial pattern in comparison with other classes and spatial patternof regional parks were unfavorable in comparison with neighborhood and district parks.

The current study aims to investigate the changes in green space of District 1 of Tabriz City in a 21-year time period (1989 to 2010) using remote sensing techniques. In this research, multi-temporalimages of LANDSAT Satellite, sensors TM and ETM+were used to model physical development andchanges in green space of the district during the years 1989 to 2010. Destructive role of expansionof urban areas and transport network have been so significant in dramatic loss of green space inDistrict 1 of Tabriz City. The obtained results revealed that during the studied period (1989 to 2010),the green space area of the district has been decreased from 255.61 ha in 1989 to 180.45 ha in 2010representing approximate 30% loss of green space area. At the same time, built-up areas have beenexpanded from 702.19 ha in 1989 to 958.14 ha in 2010 while urban transport network area of thedistrict has been developed from 101.61 ha in 1989 to 291.24 ha in 2010. Finally, some managementsterategies were recommended towards taking advantage of available opportunities for developingthe green space of the District 1 of Tabriz City of which the most important is "compilation ofcomprehensive green space management plan".

Lighvan Chay River in East Azerbaijan province named as one of the important tourism zone of theprovince because of its many natural places for leisure, entertainment and recreational opportunitieslike field trips and camping. Environmental goods and services are more open access public goods.Lack of awareness of the actual value of the environment is one of the important factors of ignoringthe environmental issues and causes environmental deteoration. Therefore, the issue of estimating theenvironmental value can be helpful to policy-makers and practitioners involved in the conservationand management of natural resources. The aim of this research is to estimate the conservation valueof the Lighvan Chay River with the use of contingent valuation method and Double–BoundedDichotomous Choice (DDC). Results from 149 questionnaires were completed from visitors (in thesummer of 2012). Estimating logit model shows that the price offer variable at 1%, marital status andsatisfaction of utilities variables were significant at the 5% level and numbers of visits variables wassignificant at the 10% level. The offered bid variable has marginal effect -0.00004 shows that anincrease a unit of bid makes 0.00003 unit decrease in WTP. In this paper willings to pay to protectthe area was calculated $2 per month per person by using Shazam 10. Since the average family sizewas 4.22, so average willings to pay of each family per month was $1.9340. Finally, Mean willingnessto pay for each family per year, was calculated $1. Therefore, the formation of the association topreserve the area is recommended. However, according to the positive effect of numbers of visitsvariable, to facilitate the area’s accessibility by improving road networks is recommended.

Biodiversity as a supporting service of forest ecosystems is declining globally due to land conversionand degradation in response to human needs for food production and settlements. To make informeddecisions, evaluation of change impacts under stakeholder-defined scenarios is considered to be anappropriate method which considers the consequences of decline. While land use/cover changemodeling is an urgent need, it usually is faced with obstacles due to the methodological problems andlack of explicit spatial data. In this paper, we applied two spatially explicit tools, The ScenarioGenerator and The Habitat Quality from the InVEST (Integrated Valuation of Ecosystem Servicesand Tradeoffs) suite of models, to project the future changes of the Sarvelat and Javaherdashtmountain system in northern Iran, based on land suitability and stakeholder's interests. We alsoexplored the existing spatial patterns of habitat quality as a proxy for biodiversity and predicted itschanges in plausible future. In this regard, after quantification of land use/cover changes based onpredictive scenario, the degrees of land degradation and habitat quality under both current and futuresituations were compared. The results showed that any changes outside of protected boundaries, canimpact habitat quality inside of the protected areas, as the new threat sources as well as externaldriving forces of the change occure. Since, the ecosystem supporting services specifically thebiodiversity, is usually ignored in landscape planning due to its complex nature of the analysis, themapped quantified outputs of these models can effectively make easier for decision makers, tounderstand the distribution patterns and existing richness of biodiversity across a landscape and makecompatible policies based on multiple ecosystem services capability.

This paper examines the likely relationship between traffic noise and other environmental variablesand bird distribution. The study was conducted in September 2012, along Asian Highway in GolestanNational Park. The sampling stations were selected in 76 points using Systematic-Random method atvarious distances between 0-250 meters from the road. Birds and environmental variables weresampled in a radius of 25 meters from each point. In each of the sampling points and in the center ofthe plot, birds and other variables such as temperature, relative humidity, traffic noise, number ofvehicles (light, heavy and medium-weight vehicles), number of horn beeping, height, the soundbarrier height, width of the road, slope and the geographical size were measured. All data wererecorded during a week of the year with the heaviest traffic and noise pollution. The birds asdependent variables were divided into three guilds namely Primary Cavity Nesting Birds, SecondaryCavity Nesting Birds and non Cavity Nesting Birds and accordingly, three prediction models weredeveloped. The result of multivariable linear regression analyses showed that in all of these modelsthe most important factor affecting birds is traffic noise.
