The accelerating speed of urbanization has a negative impact on environmental degradation, leading to the imbalance in land-use structure and scarcity its resources. existing function distribution, along with land resources, were improved this article provide people more rational use service space. This specifically contributes establishment an evaluation index system for suitability urban usin...

the present research aims to apply several approaches for suitability evaluation of lands under cultivation ofalfalfa and barley in chaharmil mechanized farming center, ardestan town, isfahan province, iran. climatic andsoil maps of the climate and soil data were provided in raster format. land evaluation carried out using maximumlimitation, parametric and multi-criteria (analytical hierarchy p...

introduction   capability evaluation can be considered as a basic strategy for land use becausethe development synchronous with the naturecan be achieved by using identifying and assessing of the ecological characteristics of the area. agricultural land suitability classification based on indigenous knowledge is vital to land-use planning (ecological capacity evaluation). execution of developme...

The dynamic nature of land qualities both in space and in time suggests that, whatever the stages of the development of an area, it is always crucial to assess land qualities in terms of their potential and suitability for specific kinds of land use on a sustainable basis. In this paper we demonstrate an integrated method of biophysical land-suitability assessment, which combines two basic land...

researchers of csiro land and water in griffith in australia have found a way to repeatedly reuse drainage water to grow crops. in the process the system will concentrate the salt in the water to a manageable level which can then be used or stored in an environmentally friendly manner. the process, known as sequential biological concentration, is based on a novel system for land, based treatmen...

Cellular automata (CA) is increasingly used to simulate various dynamic courses, e.g. urban spatial growth, forest fire spread and soil desertification. CA simulates these courses with iterative evolvements. Through simple and partial rules to form complex space structures and patterns, CA can express complex systems which are difficult to perform only with mathematical formulas. In combination...

soil and water assessment tool model, swat, uses different layers of watershed data which out of soil layer is the important one. soil layer data should be extracted from detailed soil maps. in most developing countries including iran, these detailed maps are not available except for irrigation districts and rarely for dry land farming areas and also for some strategic places of development pur...
