| 摘 要： | 从流域森林的年龄结构、面积比例和空间格局探讨了流域层次水源林结构与功能的关系,建立了流域层次结构与功能耦合模型,利用该模型对北京山区水源林进行评价。结果表明:北京山区水源林以中幼龄为主,水源林面积比例为30%,森林斑块空间配置均匀,随着年龄的增加,水源林功能将逐渐增强。

| Abstract: | This paper explores the relationship between structure and function of water conservation forest at the watershed level from the basin forest age structure,ratio of the area and spatial pattern.It establishes coupling model between structure and function at the watershed level.Finally,the model is used for evaluating the water conservation forest of Beijing mountainous area.The results show that,middle-aged and young forests are primary in the water conservation forest of Beijing mountainous area,and the area ratio is 30% of water conservation forest.The space configuration of the forest patches are uniform,and the function of forest will grow gradually along with the increase of age. |
