摘要

自然生态条件的空间差异是导致不同地区生态功能差异的重要原因

直接影响区域生态安全。通过对自然生态条件的分区评价

理清不同空间生态功能差异

可为建构区域生态安全格局提供基础支撑。以GIS技术为支撑

通过对地形地貌、特殊生态保护区、区域环境容量等方面的指标选择与综合评价

以安徽沿江地区为实证

进行生态功能空间差异分区。在分区的基础上

结合安徽沿江区域开发的方向

构建区域生态源区4个

生态廊道7个和众多的生态楔

最后提出区域生态安全格局构建的建议。

Abstract

The spatial difference of nature-ecology leads to the difference of ecological functions and directly influences the regional ecological security. Resorted to the evaluation of sub-area by the nature-ecology

the difference of ecological functions may be distinguished. Supported with GIS and by adopting the regionaliza tion method of eco-environmental restriction

indexes

such as mountain area

water density

etc

are selected and 41 counties are regarded as the basic units to be evaluated. After evaluation

regional ecological secur ity pattern is constructed with 4 ecological functional zones

7 ecological functional corridors

and some eco logical functional patches in the area along the Yangtze River in Anhui Province. Finally

some policies and suggestions abouthow to constructregional ecological security pattern are putforward.
