摘要
水源保护林林种的合理配置是密云水库水源保护林建设中的重要研究内容之一。根据北京市“八五”森林资源调查和实地调查数据 ,从发展经济与水源保护相协调的宗旨出发 ,以小班为研究单元 ,应用数量化理论 ( I)对水土流失有重要影响的主要立地因子进行了分析和排序 ,运用聚类分析方法 ,对密云水库北庄示范区 3 3 9个小班进行了不重叠内在等级聚合分类 ,将示范区划分为 6个立地类型。在分析各立地类型生态经济特点的基础上 ,结合水源保护林配置的原则 。
The collocation of forest types is one main research item of constructing waterhead oriented conservation forest in Miyun reservoir.In order to harmonize economy development with waterhead conservation,the main woodland factors that significantly affected the soil erosion were analysed and sorted with quantitative theory (I) in woodland unit of subcompartment, and 339 peaces of aggregately sorted by grade without overlap. As a result, Beizhuang demonstration region was divided into 6 woodland types, and so the scheme of forest type collocation was found based on the division. This provides scientific basis for decision making sectors to construct Miyun waterhead conservation forest.
