区域森林景观生态功能区划的理论与方法——以江西婺源县为例

Theories and Methods for Ecological Function Division of Regional Forest Landscape——Taking Wuyuan County as a Case

论述了区域森林景观生态功能区划应以空间异质性理论、等级系统理论、森林可持续经营理论、森林分类经营理论及复合生态系统理论为依据;并以婺源县为对象,采用主成分分析与模糊聚类相结合及星座图法进行分区,结果表明:采用星座图法对森林景观生态功能进行分区比利用主成分分析与模糊聚类相结合方法能得到更为满意的结果。论文将研究区区划成三大森林景观生态功能区,并指出了各区森林景观生态建设的主要战略。

The theories of spatial heterogeneity, hierarchy system, sustainable management and classified management of forest and multi-ecosystem for ecological function division of regional forest landscape are stated in the paper. Taking Wuyuan county as a case, the ecological function areas are divided using the methods of combining principal component analysis with fuzzy clustering and constellation graphics. The result shows that better result can be obtained by means of constellation graphics instead of combining principal component analysis with fuzzy clustering method. Three function areas of forest landscape are divided in Wuyuan County and its main strategies for the ecological construction of forest landscape are put forward.
