human activities induced changes in land cover/use have extensive impacts on the landscape. in recent years, these changes had an increasingly growth due to irrational use of the natural resources in iran. hence, considering the negative effects of the inappropriate use of land and land-use change, understanding of the landscape changes over time is necessary to planning and implementation of s...
inappropriate patterns and drastic changes in land-use have caused the severe environmental crisis. therefore, it is necessary to accomplish any plan in relation to establishment of different activities with respect to land capabilities and land-use evaluation thought. in this study, ecological capabilities and the site selection of land uses in babolrood basin, mazandaran province were evaluat...
sustainable exploitation of land resources is directly affected by considering soil quality which finally will also conclude environmental protection. therefore, assessing different soil quality aspects which are sensitive to various land management practices seems too important. in this study, some selected soil quality indicators have been compared in five land use systems including untouched...
nowadays because of various factors, including inappropriate land use, and indiscriminate exploitation of water resources, soil and vegetation, wide areas of the country were exposed to destruction of lands and desertification. therefore dealing with this situation requires a comprehensive land use program (water and land) and appropriate environment potency. the study area is patom district of...
Use of new techniques to evaluate irrigation areas can enhance water use efficiency in agriculture. In this study, the fuzzy analytic hierarchy Process (FAHP) was used to qualitative land suitability for sprinkler irrigation and was compared with the parametric method. Evaluation based on parametric method showed that an area of about 1597.83 hectares (31%) of the lands was highly suitable (S1)...
Soil erosion and sediment yield from watersheds confine sustainable use of land resources and is supposed as one of the most critical environmental issues. Prediction of storm wise soil erosion and sediment yield is very important, especially in arid and semiarid regions due to small number of events and high intensity of rainfall. Evaluation of soil erosion by existing models is needed as an i...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
By manifesting the response of land to human activity and impacts, degradation of forestland indicates the locations where society is in conflict with sustaining the forest environment. The analysis of land degradation in various land-use/cover patterns of Russia’s vast forest zone (about 1050 million ha, or 63% of the country) clearly demonstrates two human-induced problems, inappropriate tech...
the aim of this research was to evaluate some soil physical quality indicators using remotely sensed date, gis and geostatistical methods in baft area that is one of the most important centers of agricultural production in kerman province. therefore, soil samples were collected from 0 to 20cm depth of 183 points based on regular sampling pattern (every 250 meters) and soil physical indicators i...
land use optimization is one of the appropriate methods for soil conservation which helps decision makers and watershed planners in order to make the optimum decision among different land uses. the main objective of this research was to find the optimum area of each land use to reduce soil erosion rate as well as to increase the income of stakeholders in golroudbar watershed located in semnan p...
