北京山区水源林结构与功能关系研究

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。

Study on the Relationship between Structure and Functions of Water Conservation Forests in Mountainous Area of Beijing

In order to grasp the characteristics and the relationship between the structure and function of water conservation forest in mountainous area of Beijing,this paper firstly takes the main forest types of water conservation as the research object.Based on the analysis of the structure of the stand,it studies the relationship between the stand structure and water conservation function by the method of multi-factor analysis.The results show that the stand level,the forest species,age,canopy density,origin,level,biological volume and structure of soil are the main seven factors which impact the functions of water conservation.The results may provide a scientific basis for the management of the water conservation forest in mountainous area of Beijing.
