 Physicochemical properties of water are among the important parameters that have a special place in the health of water consumption. Therefore, the purpose of this study is to investigate the quality parameters of drinking water in Abadeh to determine its health. Sampling was carried out during June and November 2015 and 15 physical and chemical parameters in 20 samples in total taken from 10 drinking water resources was determined. Physical and chemical analyses were done according to the standard methods. The study of measured mean concentration showed that all measured physical and chemical parameters (Cl, EC, NO2, NO3, pH, SO4, HCO3, F, Na, Mg, Ca, TH, TDS, temperature, turbidity) of the underground water resources were desirable and met the expectations of national and international standards. The discharge of water wells has been a significant decrease in November. On the other hand, the results showed significant positive associations between EC with (Cl, SO4, HCO3, Ca, TH, and TDS), TDS with (Cl, SO4, HCO3, Ca, and TH), TH with (Cl, SO4, HCO3, and Ca,), Ca with (SO4, Cl, and HCO3), Cl with (SO4 and HCO3), SO4 with HCO3 and pH with F. However, the result showed significant negative associations between temperature with (pH and F). The quality of the drinking water of Abadeh city has a good and desirable condition, except for total hardness, although is in the standard range the water of this city is classified as hard water. .

Green space is effective in reducing noise pollution. The purpose of this research was to study the effect of tree species in the green space of Abadeh, as well as the number of tree plantation rows and planting width on decreasing the intensity of sound.

In this study, four stations in two areas was selected in Abadeh city including Shahid Chamran Blvd. and Northern Passageway and sampling was carried out in two turns in the morning and evening using the Cirrus sound level  meter CR: 303 in March, 2018 and 25 data in each station and 400 data in total was recorded.

The results of comparing the average sound intensity level measured in the two studied areas in the morning and evening with the Iranian national standard show that the average sound intensity level in both regions is higher than the standard; So despite the green space, there is noise pollution in both areas. The results of the study of sound intensity levels in Shahid Chamran Boulevard and along the northern passage in the morning and evening show that there is a negative correlation between the distance from the sound source (distance from the street) and the number of rows of trees planted and the average sound intensity level. This means that the greater the distance from the street and the number of rows of trees planted, the greater the amount of noise reduction.

The highest noise reduction in Shahid Chamran Boulevard is related to the distance of 54 meters from the edge of the street with 14 rows of planting with average sound intensity level for morning and evening of 65.04 and 60.96 dB, respectively, and next to the northern passage is related to the distance of 85 meters from the edge. The street was planted with 10 rows and there was a hill with an average level of sound intensity for the morning and evening of 65.04 and 64.08 dB, respectively.

Water quality is one of the issues that are directly related to the health and personal and public health of the society, and monitoring the water and providing its health conditions is of great importance. Therefore, the aim of this study was to determine the microbial quality of drinking water in Abadeh in 2015 and to compare its quality with national standards and the World Health Organization (WHO).

In this study, 122 water samples for microbial measurement and 3864 water samples for chlorimetry were analyzed from water network of Abadeh city during 2015-2016. Multiple tube fermentation method and colorimetric method were used to determine fecal and total coliform bacteria and residual chlorine, respectively. Finally, all data were analysed by one sample T-test, Chi-Square, Mann-Withney, Kruskal-Wallis and Pearson Correlation Matrix.

The results showed that the total coliform was 0 MPN/100ml in 98.36% of all samples and the fecal coliform was 0 MPN/100ml in 100% of all samples by microbial analysis and the residual chlorine were desirable in 78.0% of the samples and meet the expectations of national and international standards. Winter and summer showed the lowest and greatest amount of residual chlorine, respectively. On the other hand, the results showed significant negative associations between the amounts of the residual chlorine of the water with the presence of coliform bacteria in the water. 

Discussion and Conclusion:

The microbial index of drinking water of the Abadeh city is lower than the standard limit of the WHO microbial Index and the national standard. As a result, the quality of drinking water of the city is desirable.

Land use planning is an important tool in adequate spatial distribution of land among various activities and functions at local, regional and national planning. Recent developments in information technology such as GIS and PPS (planning support system) has significantly improved the analytical abilities of land use planners in developing land use plan based on more accurate and detailed data as well as use of more sophisticated techniques. What if? Is a PPS developed especially for land use planning? What if? uses GIS technology and land use planning models to help planners create land suitability reports, land demand analysis, land allocation, and land use protection based on pre selected assumptions and scenarios.This study reports the applications and results of what if? In developing land use scenarios for Abadeh region in Fars Province of Iran as one of the first regional Application What If? Both in Iran and abroad. The results show that What If? Despite some software and conceptual limitations, can improve planner's ability in producing various land use scenarios according to different assumptions for large regions within an adequate time frame and using the existing digital data. 
