The area of Zagros forests is continuously in danger of destruction. Therefore, the remaining forests should be carefully managed based on ecological capability evaluation. In fact, land evaluation includes prediction or assessment of land quality for a special land use with regard to production, vulnerability and management requirements. In this research, we studied the ecological capability o...
Aims & Backgrounds: Identifying tourism development capacities is an undeniable priority in any country, especially in developing countries. There are various methods for determining such zones. Given the sensitivity of forest ecosystems to human interference, the purpose of this study is to evaluate the ecological potential of Tonekabon forests. Methodology: To evaluate the ecological potentia...
In applied studies, identification and study of vegetation, for management and protection of natural ecosystems, are very important. This study was carried out in Vezg forest with an area of 308 hectares located in southeast of Yasouj city. The purpose of this study was to classify ecological species groups and survey their relation to soil physic-chemical properties and physiographic attribute...
Nowadays, the risk of degradation of wetlands is one of the main environmental challenges in the world, so continuous and long-term monitoring of ecological changes in wetlands can play a key role in their protection and proper management. In the present study, the trend of monthly changes in some of the most important ecological indicators of the aquatic environment of Shadegan wetland includi...
The wide ecological area consists of a rangeland with special vegetation and one of the key factors in rangeland management is to select Management Indicator Species (MIS). Management indicator species based on a new method such as Analytical Network Process-Decision Making Trial and Evaluation (ANP-DEMATEL) is one of the most important stages in the successful Range management as choosing a su...
The Pareto Optimal Model Assessment Cycle (POMAC), a multiple-criteria model assessment methodology, is described for exploring uncertainty in the relationships between ecological theory, model structure, and assessment data. Model performance is optimized to satisfy, simultaneously, each component of a vector of assessment criteria (model outputs), rather than the usual procedure of optimizing...
fuzzylogic computes a multi-criteria evaluation by means of either a boolean analysis, weightedlinear combination (wlc) and ordered weighted averaging (owa) of factor images. owa works withstandardized factor images and employs a variant of the wlc. it takes into account the risk associated withthe decision and degree of tradeoff associated with the variables in the analysis. in this research, ...
introduction in order to achieve sustainable development, it is necessary to obtain and adopt planning procedures based on multi criteria evaluation of natural environment. since biophysical (natural) environment has limited ecological capabilities for human use, ecological capability assessment, as an essence for environmental studies and with the aim of preventing existing crises, yields prop...
