摘要:
针对生态涵养发展型区域的生态环境状况和土地资源特点，基于PSR（压力—状态—响应）概念框架模型，构建土地生态安全综合评价指标体系，采用熵权法确定权重，运用综合指数法对重庆市丰都县2006—2011年的土地生态安全状况进行评价。结果表明，丰都县土地生态安全状态2006年处于敏感级安全状态（综合指数29.72），到2011年处于临界级安全状态（综合指数31.65）。土地生态安全状况的好转，得益于国家和地方对现有生态环境问题的治理以及对生态建设和环境保护的大力投入。2006—2011年丰都县生态涵养能力与经济社会发展水平不同步，经济的快速发展带来巨大环境压力，生态涵养和发展尚未实现良性互动。
Abstract:
According to the ecological condition and the characteristics of land resources in ecological conservation developmental areas, a comprehensive evaluation index system of land ecological security was built based on the PSR (pressure-state-response) model, and entropy weight method and comprehensive index method were employed to determine each index weight and evaluate the land ecological security condition of Fengdu County in Chongqing from 2006 to 2011. The results can be shown in the following aspects: (1) land ecological security of Fengdu County in 2006 was at sensitive level, comprehensive index of which was 29.72, while it was at critical level in 2011, comprehensive index of which rose to 31.65; (2) as time went by, the state of land ecological security had changed for the better benefiting from governance of ecosystem problems by national and local governments and effects on ecological environment construction; (3) because the rapid development of economy brought enormous environmental pressure, Fengdu County’s ecological conservation ability was not synchronized with the level of economic and social development during the period of 2006—2011.
