通过对滦河流域自然地理环境和生态特征的分析,依据提出的各级分区指标、分区方法和区域划分原则,建立流域生态分区框架体系。基于Arc GIS平台,以ISODATA聚类分析方法及相关生态分区原则,将滦河流域划分为3个一级生态区和7个二级生态区,用以表达不同地区生态环境特征和受到人类活动的影响程度,同时对各个分区的生态特性和所面临的问题进行总结和归纳。滦河流域生态分区研究可为其生态系统保护、资源高效管理和流域整体规划提供了科学依据和空间管理框架。
Abstract：Through the analysis on the natural geographical environment and ecological features of Luanhe River Basin,the ecological zoning framework system for the river basin is established in accordance with the proposed zoning indexes,zoning methods on all the levels and the relevant region partitioning principle. Based on the platform of Arc GIS,Luanhe Rver Basin is divided into 3 first-level ecological zones and 7 second-level ecological zones with the method of ISODATA cluster analysis and the related ecological zoning principle,so as to give prominences to the eco-environment features and the degrees of the impacts from the human activities and summarize the ecological characteristics of all the zones and the problems faced simultaneously therein. The study on the ecological zoning for Luanhe River Basin can provide the scientific basis and space management framework for the ecological protection,high efficient management and the integrated planning of the river basin.
