摘要
以西安市为研究对象,运用DPSIR模型建立评价指标体系,采用层次分析法和熵权法综合确定指标权重,利用多因素综合评价法对西安市2006~2016年的土地生态安全状况进行评价,以指导区域土地合理、可持续利用,为政府部门相关决策提供参考,推进区域生态文明建设。研究表明,西安市2006~2016年间土地生态安全状况有了一定改善,系统状态经历了不安全到临界安全到较安全三个阶段,土地生态安全综合指数值呈现出波动性上升趋势。
Taking Xi'an as the research object,this paper establishes the evaluation index system by using DPSIR model,and uses the analytic hierarchy process and the entropy method to synthetically determine the index weights.The multi-factor comprehensive evaluation method is used to evaluate the land ecological security status in Xi'an in 2006~2016,to guide the land used in a reosonable and sustainable way,provide a reference for relevant government departments'decision-making and promote the construction of regional ecological civilization.The results show that the ecological security of the land in Xi'an has been improved to a certain extent from 2006 to2016,and the system status has gone from unsafe to critical safety to safer.The index of ecological security of land shows a fluctuating upward trend.
