为了准确把握北京山区水源林林分特征,掌握其结构与功能的关系,以北京山区的水源林16种森林类型作为研究对象,分析了林分的结构特征;采用因子分析方法对林分结构与水源涵养功能关系进行多因子分析研究,结果表明:在林分层次上,影响水源涵养功能的林分结构因子主要是林分树种组成、年龄、郁闭度、起源、层次、生物量以及土壤结构7个因子。研究结果可为北京山区水源林经营提供科学依据。
In order to accurately grasp the characteristics of water source forest in Beijing mountainous area and master the relationship between its structure and function, 16 forest types of water source forest in Beijing mountainous area were taken as research objects, and the structural characteristics of forest were analyzed. The results showed that: At the stand level, the main stand structure factors affecting the water conservation function were the stand tree species composition, age, canopy density, origin, level, biomass and soil structure 7 factors. The results can provide a scientific basis for the management of water source forests in mountainous areas of Beijing.
