land use planning is a science that determines the type of land use through studying the ecological character of the land as well as its socio-economic structure. it is possible to plan for the appropriate use of the land and to enhance the present management of the land use by utilizing geographical information system (gis). to this end, our investigators identified and took steps toward devel...

In this study, an inexact stochastic fuzzy programming (ISFP) model is proposed for land-use allocation (LUA) and environmental/ecological planning at a watershed level, where uncertainties associated with land-use parameters, benefit functions, and environmental/ecological requirements are described as discrete intervals, probabilities and fuzzy sets. In this model, an interval stochastic fuzz...

Many resource allocation issues, such as land useor irrigation planning, require input from extensive spatial databases and involve complex decisionmaking problems. Spatial decision support systems (SDSS) are designed to make these issues more transparent and to support the design and evaluationof resource allocation alternatives. Recent developments in this Ž eld focus on the design of allocat...

over the past few decades, several models such as the lp model have been used for managing watersheds and determining optimal cultivation pattern for agricultural planning. management and planning methods are the most important applied tools of management science for optimal allocating resources in order to gain the most profits in the different fields including natural resources, water resourc...

Mapping ecosystem services (ESs) is an important tool for providing the quantitative information necessary for the optimal use and protection of ecosystems and biodiversity. A common mapping approach is to apply established empirical relationships to ecosystem property maps. Often, ecosystem properties that provide services to humanity are strongly related to the land use and land cover, where ...

In the process of traditional economy transforming into modern economy in china, farmer’s diversification phenomena has arisen and developed and will continue a long time in the future. Accordingly, the general economic type of farmer diversification will effect on the rural source allocation. The land use behavior characteristics of diversification farmer are the aims of the study. Theoretic a...

abstract- inadequate water supply is the major problem for agriculture in arid and semi-arid regions. thus, effective management should be considered for water resources planning. in this research, a model was provided which is able to estimate optimal land and water allocation in the doroodzan irrigation network. optimal water management model was used at farm level to evaluate different defic...
