Abstract
Perception of aesthetic concept is one of the most important and required issues in designing recreational areas. Methods of aesthetic evaluation divide into two distinct parts: community perception evaluation and expert evaluation. In expert evaluation methode, valuation is based on visual concepts and objective beauty of landscape through scientific methods, but in community perception evaluation, evaluation is based on the sense experience, values and cognition of the individuals. The goal of this paper is objective assessment of landscape aesthetic values in Ziarat watershed basin using artificial neural network through multi-layer perceptron method. Mapping and standardization of criteria were done after reviewing the available documents, determining the effective criteria and generating the relevant layers for the study. Then, the suitability map of aesthetic values was obtained using the MLP model. The probability image created during the process was used to assess the accuracy through ROC. The ROC index was calculated at 0.875 which endorsed the accuracy of the model. Our experience shows that artificial neural network method is an appropriate tool for landscape aesthetic values modeling in the study area. The results of this model could eventually ease site selection process for recreational areas in more beautiful places.

Abstract
This study has been done to provide a management plan to protect the marine ecosystem values in North Pars number three through the identification of biological environment of the sea and to estimate the percentage of seabed coverage study was based on direct observations, measurements and laboratory analysis to evaluate the results. In general, the parameters include coastal ecosystems (coastal zone to sub-tidal zone), aquatic ecosystems (aquatic plants, plankton, macrobenthic invertebrates and coral communities), species at risk and protected areas. For this purpose, a preliminary study of marine has been done in two coastal zone between tidal and sub-tidal, by using Mantato, diving operations and underwater photography and grab Methods. Study of the components of the seabed coverage in tidal zone has been performed by using diving operations along one transect perpendicular to the shore and in three stations. To evaluate the the components of the seabed coverage, life cover percentage such as (soft coral, hard coral, dead coral, seaweed, urchin, sea cucumbers, clams, mollusks, crustaceans, and other inorganic materials) were determined. The results of study, indicate the moderate diversity of coastal zone in terms of geomorphological, coastal bed type and also sensitive biological resources in study area.

Abstract
Power generation by fossil fuels causes environmental pollution especially greenhouse gases (GHGs). Although nuclear power is known as a no-GHG technology, but there is GHG emission in life cycle of nuclear power plant.
Life Cycle Assessment (LCA) is a “cradle to grave” approach for assessing different systems, which could assess all environmental impacts in life cycle of a process. Therefore In order to assessing GHG emission of Bushehr nuclear power plant, LCA is a useful tool.
In environmental impacts classification by LCA, “climate change” is an impact class. The method for characterization of climate change is “GWP100”. Results of LCA of Bushehr nuclear power plant indicate that NOx and CO2 emissions have the most important impacts in life cycle of Bushehr power plant.

Abstract
The petrochemistry has potentially huge environmental pollution hazards and harmful impacts on environment so it knowns as a pollutant industry over the world. On the other hand, there is special focus on developping the petrochemical industry because of its considerable benefits in our country.
According to our upstream environmental laws and regulations, it is necessary to prepare an environmental impact assessment report before construction of any petrochemical plants. This report can be a powerfull tool for identification and management of project impacts. But our practices in petrochemical plants showed that current process is not successful for this purpose. In this study, the authors discuss on current environmental impact assessment process at first and then provide some suggestions and recommendations for improving the environmental impact assessment studies.

Abstract
Today the world is experiencing an unprecedented urbanization. Population growth and urbanization are effective factors on increasing the air temperature in urban areas which cause heat island on these areas than surrounding and the resulted effects from that can play an important and major role in air quality and consequently public health. In this study, Landsat 5 TM data in 2009 as a case study in Tehran metropolis was studied and mono-window algorithm was used for retrieving the distribution of land surface temperature and determination of local heat island effects. In addition, the correlation between LST and the normalized difference vegetation index (NDVI), the normalized difference build-up index (NDBI), the normalized difference bare land index (NDBaI), the normalized difference water index (NDWI), were analyzed to explore the impacts of the green and bare land and the water and build-up land on the urban heat island. The results indicate that the effect of urban heat island in Tehran is mainly located in west industrial and east and southeast Mountain regions. The correlation between LST and NDVI, NDBI, NDWI, NDBaI also indicates that the negative correlation of LST and NDVI and NDWI suggests that the green and water land could weaken the effect on urban heat island, while the positive correlation between LST and NDBI and NDBaI means that the built-up and Bare land can strengthen the effect of urban heat island in our case study.
