摘要 基于P-S-R模型,从环境、社会、经济等方面构建一套土地生态安全评价指标体系,结合熵权赋权法和综合指数法对2011—2015年湖南省土地资源生态安全性进行了分析和评价。结果表明:2011—2015年湖南省整体土地生态安全状态呈现改善趋势,目前已处于良好级别;但仍存在一些威胁湖南省土地生态安全的不安全因素。因此,要求人们必须继续采取积极有效的政策和措施来克服这些不安全因素。 Based on P-S-R model,we took mainly the environment,society and economy etc. as a set of evaluation index,and built a comprehensive model with respect to the ecological safety of the land resources of Hunan Province. Furthermore,combined the entropy and synthetic index method,we analyzed and evaluated the land ecological safety of Hunan Province from 2011 to 2015. The results showed that from2011 to 2015,the land ecological security status of Hunan Province presented an improving trend and it was at a good level currently. However,there still exists some insecure factors which will still threat the land ecological safety of Hunan Province. Therefore,it is necessary that people continuously take the positive policies and the effective measures to conquer these insecure factors.
