  Nitrate and nitrite ions are important pollutants of surface waters and groundwater resources which can have adverse effects on the health of consumers. Therefore the purpose of this study was determination of nitrate and nitrite concentrations in groundwater resources of Dehgolan City.Groundwater samples were collected from20 selected stations during before and after of fertilization periods in 2012. The samples are prepared according to APHA method and concentrations of nitrate and nitrite anions analyzed using spectrophotometer on the wavelengths of 420 and 543 nm respectively. All statistical analyses were performed using the SPSS statistical package.The results showed that mean concentrations of nitrate and nitrite anions in groundwater samples for before fertilization period were 8.66±0.97 and 0.001±0.0003 mg L-1, respectively, and for after fertilization period were 69.20±8.82 and 0.013±0.006 mg L-1, respectively. Also comparison of the mean concentration of nitrate in groundwater samples after fertilization period with Iran DOE permissible limits for drinking use showed that significant difference (p<0.05). So that the mean concentration of nitrate significantly upper than permissible limits.Conclusion: According to the results of this study because of the mean concentration of nitrate significantly upper than permissible limits, therefore long-term excessive use of agricultural inputs and construction of polluting industries, can cause a threat to groundwater resources, and health of residents in this area.

  Today lack of urban green space is the basic problem of cities. Urban green space is one of the very important land use problems in the city and minimum per capita green space also is a criteria for assessment and determination of sustainable cities. DEHGOLAN city in  one  of cities that does not have the proper distribution of green space, so that its per capita is 57/2 square meters per person. In this city, some neighborhoods do not have any green space and some neighborhoods have more green space. This article aims to provide a suitable model for optimal distribution of green space in city, according to  components such as population, communication networks, facilities, space, security and arid areas in the neighborhoods. The deployed research methods is descriptive - analytical and data was collected based on field surveys. TOPSIS and GIS techniques have been used in this study. According to above criteria,  each neighborhood has been studied and analyzed separately. Prioritization of green space in the first phase was conducted in six step of TOPSIS. Results in this phase showed that the KLE_MLE district have first priority for green space allocation. In the second stage, firstly the  data was collected and database in GIS was formed, then according to the importance of each criteria in green space, appropriate weights were assigned. The results of GIS and TOPSIS combined and KLE_MLE district with /0537 (CL) was taken in the first place. The final result of this study indicates the important applications of TOPSIS and GIS in urban green space Prioritization and provides optimum dispersion pattern based on the criteria and needs of the urban population.   Manuscript profile
