通过使用分析压力、状态、响应三者之间关系的(PSR)模型,对长江经济带十一个省市的生态安全状况进行评估,最终结合相关数据进行比较分析.研究结果表明:长江经济带2010-2015年生态安全综合指数(LESI指数)和压力指数总体呈增长趋势,其中,LESI指数呈现"W"分布;状态指数和相应指数总体呈现下降趋势;长江经济带2010 -2015年生态安全综合指数、压力指数、状态指数、响应指数省际差异明显,部分省市响应指数呈现正"U"型分布;长江经济带所有省市生态安全状况都处于不安全和较为安全(0.2-0.6)区间,表明所有省市距离生态安全还有一定差距.通过对此分析,笔者提出针对性的建议.

By using the pressure-state-response(PSR)model,the ecological security situation of the 11 provinces and cities in the Yangtze river economic zone was evaluated.Finally,we compare and analyze the relevant data.The results show that:The comprehensive index of ecological security index(LESI index) and the stress index showed a general growth trend of the Yangtze river economic zone in 2010-2015,a-mong which,LESI index presents"W"distribution;The state index and the response index are decreasing in general;T he ecological security composite index,pressure index,status index and response index of ...
