Water quality is presented by its physicochemical and biological specification. The aim of this study was to analyze the physicochemical characteristic of waters (river, drinking, hybrid and pure water) including total hardness, magnesium, nitrite and ammonia (mg/L) which were determined based on the standard protocols of the EPA (2010) using photometer, Palintest, 8000. Furthermore, dissolved oxygen (mg/L), temperature (ºC) and pH were determined by oxygen meter, calorimeter and pH meter, respectively, with 3 repeats and in the limnology laboratory of Birjand University. In river water, the concentration of nitrogen is higher compared to other water sources due to the physicochemical reactions (especially due to the disposal of ammonia into water). For the hybrid water, consisting of drinking water plus pure water, the chlorine concentration (0.4 mg/L) was greater than the average (0.15 mg/L). The total hardness of the same (125 mg/L) was however lower than the average (185 mg/L). Finally, it is recommended that biological indicators such as the presence of rotifers, tubular cross-sectional fish, and salmon (which normally live in clean water) be used to assess the qualitative characteristics of the water. This is due to the fact that there are normally more living creatures in waters which can hold salts.

The worries and concerns of today's human societies have caused serious damage to the human spirit, so man returns to the natural environment to escape from this space. Therefore, ecotourism is one of the growing industries in the world. There are many criteria and definitions for identifying the potential of the environment Which has sometimes caused it to be unmeasured. Since the beauty of the landscape is the main element that is faced in the natural environment in relation to tourism and recreation and not only benefits the viewer but also has an important contribution to the overall desirability of an area. Therefore, in order to understand the aesthetic values of the landscape, one must go beyond the process of identifying the physical and biological signs in the landscape.Therefore, in this study, using 19 tourism index points in Haraz basin, 19 criteria with different topics were evaluated. In this study, environments were first classified by clustering method. Then, effective criteria were extracted by principal components method. Finally, by modeling the linear regression, the criteria were imaged in a step-by-step manner with four criteria (vegetation, texture, unique effects and effect quality) and the visual image value was estimated with 80% accuracy.

Despite the increasingly trend of developmental activities that are likely to change the structure and change or eliminate landscape functions and processes in Iran ultimately, it seems necessary to consider the visual effect in EIA studies especially in northern ecosystem of the country.

This study aimed to quantify the visual criteria of naturalness and complexity using SHDI, SHEI, PLAND, LPI, PR, PD, and NP measurements in the area of Tonekabon's Dohezar-Sehezar watershed from two viewpoints. The visible range, after land use mapping and production of DSM and transmitting of visibility points to GIS, was obtained using the Visibility instruction in GIS, which analyzed the visible range at two points.

According to the PLAND index, the highest amount pertained to forest land use, and their amounts for forest, agriculture, and rangeland land uses found 0.1499, 0.0001, and 0.0021 respectively that detected the naturalness in the first- viewpoint was more than the second viewpoint, and this area has been less affected by human interferences. At the second point, except for the SHEI value which was less than the first point ( 0.0927), the amount of SHDI (0.0927), PR(7000), PD (2.507), and NP(2058000) indices grater than second point obtained.

The use of landscape metrics with regard to their capabilities can be a useful step to early identification of the impacts of development on the structure of landscape. The proposed approach can be the basis for developing a new method to understanding the effects of landscape changing in planning and management fields.

This study aimed to select a suitable location for the landfill site of hazardous waste in Qazvin province. The study area maps were first updated using satellite imagery. Effective criteria for landfill selection were formulated using the Delphi questionnaire and prioritized by ANP using library studies and standards of relevant and global organizations as well as assessing area conditions and effective factors. The digital information layers were introduced into GIS and weighting and modifications to the information layers and considering the minimum area were determined, suitable locations for landfilling of special waste. The obtained sites were screened, inappropriate references were screened and 9 sites were selected as the best site using criteria and constraints obtained and adapted to the ground reality and environmental conditions. Based on the results of the layers overlap, none of the selected points had a value of one and the selected locations had a maximum score of 4.78. Finally, using TOPSIS software, prioritization was made between the selected options and the third site was identified as the best location for the landfill site.

The purpose of this study was to evaluate the impact of the enclosure on the quality of gonbad rangelands using density, diversity and species richness indices.. vegetation sampling was done based on systematic random sampling. Five transects of 1000 meters were considered separately for vegetation characteristics in each region. The species density was calculated by counting the number of bases in the plot, the species diversity was calculated by the Shannon-Wiener diversity index and species richness counting the number of species in each plot. After analyzing, it was determined that the enclosure has a significant effect on species density, species diversity and species richness. Generally, palatability plants and diversity and richness of the species were significantly increased in the protected area. Species diversity in the grazed area increased from 1/798 in the protected area to 2/236. There was a significant decrease in the amount of species richness in the affected area, and from 11.626 species per square meter in the protected area, it reached 9.253 species per square meter. The results indicate that the specimen area has been enclosed with enclosure, vegetation characteristics in the path of sequencing and achieving ideal conditions, but it still needs attention and continued
