Abstract:

Regionalization of ecological function is a synthetical process which refers to various indices of different characters. In this paper, we studied the ecological function regionalization by applying “decomposing step method” which is a combination of qualitative and quantitative methods. In the first step, in virtue of Arc GIS, we analyzed the natural structure of Kaihua county, making use of its maps of landform, vegetation, hydrology, so as to realize the primary plot of ecological function region. Secondly, we carried out the clustering analysis on the basis of town administrative cells, using data supported by “Kaihua Annual Statistics” and data from environment protection, agriculture,and forest departments etc. The repartition of ecological function region was then achieved with the combination of the target outlined in “2004~2020 Kaihua Strategic Planning”. The second step is namely the embodiment of economic and social factors. Based on this process, we proposed the particular objective and management measures for the ecological construction and environment protection in regions with different ecological functions.
