Determination of land capability for optimal use of land to prevent land degradation and improper use of lands is an effective step towards sustainable development strategy. Regarding the importance of subject, in this study in first ecological potential for usual land uses in Iran (forestry, ecotourism, agriculture, range management, residential areas development and conservation) in Babolro...
land use optimization using linear programing is a method in watershed management for access to production sustainability and decreasing of soil erosion. the sensitivity analysis of the model can with investigation of results influence form changes in input parameters, lead to decrease the uncertainty in decision-making of management programs. so in this research, linear programming model using...
In this paper, we explore the interaction between taxation and local public good (LPG) and how it impacts the spatial pattern in the framework of new economic geography (NEG). In the benchmark case of a pure LPG, the system displays a similar location pattern to the existing NEG taxation model, although the tax reduces the market size of manufactured goods. However, when we consider the inheren...
In this study the effects of land use change from salt affected land to cropland on soil quality indicators were studied in Chahafzal region, Yazd province, central Iran. Composite soil samples from 0-30 and 30-60 cm depths of saline and cultivated land were taken. Soil particle size distribution, calcium carbonate, Available water capacity (AWC), Electrical conductivity (ECe), Soil reaction (p...
Analyzing the process of land use and cover changes during long periods of time and predicting the future changes is highly important and useful for the land use managers. In this study, the land use maps in the Ardabil plain in north-west part of Iran for four periods (1989, 1998, 2009 and 2013) are extracted and analyzed through remote sensing technique, using the land-sat satellite images. T...
Study of land use effects on soil quality indicators leads to sustainable management and preventing progressive land degradation. The TM (1987) and ETM+ (2000 and 2005) data were used to study land use change effects in Mahan-Joopar area on soil quality indicators. Fifty random soil samples from 0-30 cm depth of each land use were taken using provided maps. Organic matter, microbial respiration...
Land use change is one of the most important factors of global environmental change. So, understanding and predicting the causes, processes and consequences of land use and land cover has become a major challenge. The Remote Sensing and Geographic Information System (GIS) technologies can be used effectively to detect and quantify of land use changes and its effects on the environment. The pur...
introduction: the modis facility for the earth observing system is a key element that supports ambitious goals related to studying the earth as a system. one of the modis products is high quality land surface temperature data that product in terra and aqua platforms. knowledge of the lst provides information on the temporal and spatial variations of the surface equilibrium state and is of funda...
Today, there are many factors affecting watersheds, consequently changing natural ecosystems succession. The aim of this study was to investigate the effect of drought events on land use changes at Doiraj Watershed of Ilam Province from 1996 to 2015. For this purpose, Landsat satellite images were used for land use change monitoring and Standardized Precipitation Index (SPI) was applied for dro...
in the recent years, human activities have led to changes in land use and land cover, consequently, these changes lead to the structure and function of ecosystems. spatial-temporal change detection of land use is important to understand the relationships and interactions between human and natural resources and to make appropriate decisions due to changes in land use and land cover occurs in bro...
