Assessing the quality of groundwater is important to ensure the sustainable safe use of these resources. However, describing the overall water quality condition is difficult due to the spatial variability of multiple contaminants and the wide range of indicators (chemical, physical and biological) that could be measured. Therefore, in this case study, some water quality […]
For the successful tree establishment, an evaluation of land suitability is necessary. In this paper, we demonstrate how to implement fuzzy classification of land suitability in a GIS environment for afforestation with Juglans regia in Gharnaveh Watershed of Golestan Province in Iran. Juglans regia is one of the most important agro-forestry species in many rural […]
Rangelands are important for plant productivity, livestock production, wildlife, conservation of soil and water resources, and etc. One of the main problem of rangeland is that has not been used based on its potential that leads to more degradation of rangelands. The purpose of this study was to evaluate the range management capability of Badreh […]
The major aim of processing satellite images is to prepare topical and effective maps. The selection of appropriate classification methods plays an important role. Among various methods existing for image classification, artificial neural network method is of high accuracy. In present study, TM images of 1987, and ETM+ images of 2000 and 2006 were analyzed […]
The purpose of this study was identifying rangeland development and restoration operations targets. This study was conducted in Hossein Abad Bazoft basin with 7162 ha area, located in south east of Farsan County, Chaharmahal and Bakhtiari Province, Iran. The basin has various land uses including rangeland, forest, irrigated farm and garden, dry farm, residential area […]
Subalpine ecosystems are highly fragile as compared to biological and environmental factors. Landslide is one of the ruinous upshots of this ecosystem. One of the impressionable areas in the cause of natural factor is Masoleh watershed in western Alborz Mt, (Iran). In order to landslide hazard zonation, landslide index and frequency ratio method based on […]
To determine the potential habitat of two rangeland species of Salsola rigida and Agropyron trichophorum in Qasr-e-Shirin, Iran, Geographic Information Systems (GIS) and Remote Sensing (RS) techniques were used. At first, several maps (vegetation cover and land uses maps and thematic maps of various organizations) were collected or prepared. For digitizing geology, vegetation and conventional […]
Land use may be regarded as one of the most important factors affecting the environment with respect to human activities. So far, destroying the rangelands and changing them into the waste lands and poor rangelands has been proposed as the most significant variations of land use done by human beings. This paper has been conducted […]
