林分结构与水源涵养功能耦合关系研究——以北京八达岭林场为例
Relationship between Forest Stand Structure and Function of Water Conservation——A Case Study of Badaling Forest Farm
摘要
Abstract
Fourteen factors related to forest stand structure were selected from the data of forest inventory for Badaling Forest Farm of Beijing in 2004, including the origin, the average high of tree and the closure, and so on. The relationship between these factors and function of water conservation of forest were studied through factor analysis, and based on this analysis. The model of coupling relationship between structure and function was built. According to the results of the model, a comprehensive analysis was made for each class in study area. The results showed that water conservation function of broad-leaved forests was better than that of coniferous forests, and natural forests were better than plantations. The forests with better water conservation function were characterized: they originated from natural forests, they were broad-leaved forests or mixed forests, their covering rates were over 75%, the degrees of closure were between 0. 5 to 0. 8, and they were middle-aged forests.关键词
