Abstract
The suitability evaluation of reserve resources of cultivated land provides a scientific basis for reasonable exploitation and utilization of these lands aiming to ensure food supplies of China.Taking the whole reserve resources of cultivated land in Ji'ning Dis-trict as the evaluation object based on database in Second Rural Land Investigation of China,six factors of inherent and external were adopted,the weight contributions of individual factors were determined combining the Delphi method and an analytic hierarchy process (AHP). The suitability indices of each evaluation unit were calculated by using the exponential test, and then the suitability grades were classified. Evaluation results showed that about 4 603.52 hm2reserve resources of cultivated land had suitable physical quality, among which grade high suitability, moderate suitability, low suitability accounted for 18.52%, 33.64% and 47.84%, respectively. Zhaijiagou village in the south of Ji'ning district and partial low-lying land in the village of Dashihao,and so on,where had large area reserve resources of cultivated land, might be a key place to develop. The purpose was under the background of urbanization, the study of this paper could provide reference for the whole of Inner Mongolia,and the other similar area back-up resources development and utilization.关键词
