昆明市云龙水库水源涵养林群落结构功能分析

针对昆明市云龙水库水源涵养林云南松群落,选取了15块标准地作为典型林分类型的代表进行群落结构研究。运用坐标综合分析法和分级评定法,评价了不同林分类型的群落结构及其与水源涵养生态服务功能的关系,结果表明:具有乔灌草复层紧密结构的针叶林和软阔树种的混交林分为水源涵养功能最优林分类型,针叶林与硬阔树种混交的林分水源涵养功能次之,草类—云南松单层纯林的水源涵养功能最差。

Analysis on the Functions of Community Structure of Headwater Protection Forests of Yunlong Reservoir, Kunming

This paper mainly focuses on Yunnan Pine community of Yunlong dam’s headwater conservation forest in Kunming. 15 sampling plots were selected as a typical representative for this type of study in the paper. Through the coordinate comprehensive analysis and classified evaluation, this paper appraised different structures of various communities and their relationship with the functions of ecological water conservation. It concludes that the mixed species of plants and conifer with complex structure of arbor, shrub and lawn were the best water conservation forests, the mixed species of hard broadleaf forests and coniferous forest were inferior to the former, and the single of pure forests of Yunnan Pine with grass were the worst.
