Abstract

Land consolidation is the basis of making the land arrangement special plan, meanwhile, land consolidation sub area, ascertaining land consolidation item and setting land consolidation indices are mainly depended on land consolidation potentiality, so it is necessary to do this research. As the most important pattern of land consolidation, potential evaluation of cultivated land consolidation is more essential. However as far as theoretical and empirical researches in China's mainland, few discuss on the connotation and evaluation of cultivated land consolidation potentiality. Facing present condition, in order to analyze potentiality of cultivated land, some research is compiled in this paper. Nowadays, spatial decision support system (SDSS) has been applied in variety of profession and domain not only in the fundamental research but also in the concrete project application. SDSS not only solves quantitative problems but also deals well with the uncertain, fuzzy information. It can help decision-makers to make sensible decisions. Facing the land consolidation problem, aiming at evaluating the potential of land consolidation effectively, we developed a SDSS for evaluating potential of land consolidation. In this research, land consolidation potentiality was evaluated from the following four parts, potential of new effective area of arable land, potential of improving productivity, potential of reducing production costs and potential of improving the ecological environment. In order to check the result of the evaluation, Fuzzy Assessment Model, Gray Correlation Analysis Model and PPE model based on RGRA are adopted in this SDSS. Through this study, we provided to the land managers and political departments an approach that is scientifically sound and practical.
