摘要
为了对川中丘陵区和其他丘陵地区县级尺度范围的生态功能区划提供参考,针对当前县级尺度生态功能区划研究较少的现状及川中丘陵区的发展需要,结合川中丘陵区自然地理要素特征与盐亭县的实例,对川中丘陵区县级尺度生态功能区划的原则、依据和方法进行了探讨。运用RS和GIS技术,采用定性与定量相结合的分析方法,将盐亭县划分为4个生态功能区、10个生态功能亚区,并根据不同生态功能亚区特点,明确了各区的主导生态功能和主要环境问题。
The principle,basis and method of ecological function division at county scale were discussed based on natural geographic element characteristics in Sichuan hilly areas and the reality of Yanting County to provide the scientific basis for ecological function division at county scale in Sichuan hilly areas.Yanting County could be divided into 10 ecological function sub-regions and four ecological function regions by RS and GIS technology and qualitative and quantitative combination analysis method.The leading ecological function and main environmentproblems of different ecological function sub-regions were defined according to characteristics of different ecological function sub-regions.
