| 摘 要： | 针对土地资源利用过程中出现的粮食安全问题、土地生态质量问题及土地经济、社会安全问题,参照压力一状态一响应(PRS)评价模式,构建评价指标体系。采用层次分析法确定权重,运用二次函数综合的方法对区域土地资源安全程度作了评价。研究表明,重庆市土地资源处于初步安全状态,从1999年和2004年土地综合安全值来看,土地资源安全整体状况处于好转之中。

| Abstract: | The paper aims at the problems of food security,the decline in land ecological quality and the social and economical security in the process of land utilization.A system of evaluation criterions was set up based on the PRS evaluation model of land use.The weigh of all the criterions was then determined using Delphi method.Finally, quadratic function was used to work out the degree of land security.The result indicates that in terms of the land security value,the status of land security in Chongqing was better in 2004 compared with that in 1999,and now is at the beginning of a security stage. |
