摘要:

本文依据武陵山区遥感调查数据及社会经济统计数据,运用灰色关联度模型计算2000年和2010年生态安全综合指数,并对研究区生态安全综合指数的时空演变特征进行分析.结果表明:(1)2000年研究区生态安全综合指数处于Ⅲ级临界安全和Ⅱ级较差安全水平,2010年生态安全综合指数整体处于Ⅲ级临界安全水平之上;(2)2期Moran's I指数分别为0.3828及0.4411,P值均小于0.01,生态安全综合指数在空间上表现出较强正相关,存在空间聚集性,且2010年聚集性更强;(3)武陵山区2期生态安全综合指数空间分布出现较大变化,且都呈现高值,低值聚集;(4)生态安全综合指数与扶贫人口比例及森林覆盖率呈正相关,与农民人均纯收入没有必然的联系.

Abstract:

With the rapid growth of global economy and population, the ecological environment was severely influenced by the human activity, and the excessive human exploitation of resources has brought continuously increasing pressure to resources and environment. As a result, a series of global ecological problems were caused, such as resource wars, environmental pollution, ecological refugees and environmental health problems. The ecological environmental problem has been a serious threat to our country's economic development and human life security. Meanwhile, the ecological security has gradually become a hot issue which drew increasing attentions of the international communities. Based on the physical, social and economic characteristics of the research area, an evaluation system of ecological security was built up, and the grey relational analysis method was used to calculate the ecological security index of the mountainous area of Wuling. This research analyzed the study area's ecological security pattern, and the results are showed as follow: (1) there was a huge increase in the ecological security index between 2000 to 2010, and the Qiandong area presented the fastest increasing trend; (2) a significant positive correlation was presented between the ecological security index and the space in 2000 and 2010, and the spatial aggregation effect of 2010 was stronger; (3) a high accumulation and a low accumulation pattern was revealed in the spatial distribution of ecological security index within the mountainous area of Wuling, and the spatial distribution pattern of ecological security changed greatly between 2000 and 2010. Because of the rich natural resources of Wuling area, the scientific and reasonable evaluation of the regional ecological environment is necessary to provide specific and feasible suggestions to the relevant functional departments for environmental protection.
