黔东南生态安全评价分析

Ecological Safety Evaluation of the Qian Dongnan Prefecture

为了测试黔东南州生态安全状况,研究采用实地考察和统计分析的方法,构建黔东南州16县市P-S-R生态安全体系,结合熵权法及综合指数法计算各县市综合生态安全指数。结果表明,黔东南州16县市生态安全综合平均指数为0.47,生态安全压力平均指数为1.0,生态安全状态平均指数仅为0.18,生态安全响应平均指数为0.19;并且提出了加强生态安全观培养、减缓人口增长、加强土地资源保护的几点建议。

To test ecological safety condition in Qian Dongnan Prefecture, this paper establishes P-S-R ecological safety system in 16 counties and cities in Qian Dongnan Prefecture using on-the-spot investigation as well as statisti- cal analysis and compute comprehensive ecological safety index in each county by combination of entropy method and comprehensive index method. Results show that the ecological safety comprehensive index on average of the 16 counties and cities in Qian Dongnan Prefecture is 0.47, the ecological pressure index on average is 1.0, the ecological situation index on average is 0.18 and the ecological response index on average is 0.19. It is pointed out that methods should be taken such as strengthening of development of ecological safety concept, slower speed of population increasing and protection of land resources.
