【摘要】：基于PSR模型框架,借鉴熵权法与灰色关联思想,构建区域生态安全综合评价模型,以武陵山片区为例对跨省区的不同经济体进行生态安全综合评价与比较分析。结果表明:1在2008—2014年间,武陵山片区的生态安全综合指数、生态状态指数和生态响应指数总体上均呈上升趋势,生态压力指数总体却呈下降趋势,该时期内武陵山片区在社会经济发展的同时,生态环境整体状况逐步好转。2武陵山片区的生态环境改善显著,但大部分市州生态安全等级仍处于第Ⅲ级,生态安全状况一般,生态环境仍面临巨大压力。3武陵山片区各市州的生态安全状况差异显著,各市州在制订具体应对政策措施时,既要借鉴片区内生态环境改善的有益经验,也要关注片区生态安全的差异,针对不同情况采取相应对策。
[Abstract]:Based on the framework of PSR model, the comprehensive evaluation model of regional ecological security is constructed based on entropy weight method and grey relational theory. Taking Wulingshan region as an example, the ecological security comprehensive evaluation and comparative analysis of different economies across provinces are carried out. The results show that the Wulingshan integrated index of ecological security in Wulingshan region from 2008 to 2014. The ecological state index and ecological response index showed an upward trend on the whole, but the overall ecological pressure index showed a downward trend. During this period, Wuling Mountain region in the social and economic development at the same time. 2 the ecological environment of Wuling Mountain area has improved significantly, but the ecological security level of most cities is still in the third grade, and the ecological security situation is general. The ecological environment is still facing great pressure. 3. The ecological security situation of each city in Wuling Mountain region is different significantly. The city states should draw lessons from the beneficial experience of ecological environment improvement in Wuling Mountain region when formulating specific policy measures. We should also pay attention to the differences of ecological security in different areas and take corresponding countermeasures for different situations.

【正文快照】： 生态安全与国家的政治安全、军事安全、领土安全、金融安全一样,是国家安全的重要组成部分[1]。安全的生态环境是实现区域经济社会可持续发展的重要基础与前提。维护区域生态安全,关键是加强区域生态环境管理,而区域生态安全评价可以为区域生态环境管理和决策提供科学依据。国
