    北京山区水源涵养林典型森林类型结构特征研究

    Structural characteristics of typical water conservation forests in mountain areas of Beijing.

    • 摘要: 通过对北京山区水源涵养林区112块标准地,从林分水平结构、垂直结构、土壤结构等方面进行系统研究,得出北京山区水源涵养林整体及18种典型森林类型的结构特征。结果表明:目前北京山区水源涵养林中天然林多为异龄、复层和混交结构,而人工林多数是同龄、单层和纯林结构;从林分稳定性等角度来看,北京山区水源涵养林天然林结构要优于人工林结构。

       

      Abstract: We investigated 112 sample plots of water conservation forests in the mountain areas of Beijing in terms of their horizontal structure, vertical structure and soil texture, and summarized the structural characteristics of the entire water conservation forests as well as 18 typical forest types. The results showed that, in the mountain areas of Beijing, the natural conservation forests had mostly uneven-aged, double-layer and mixed structure at present; whilst the most plantation conservation forests had characteristics of even age, single level and pure species composition. From the view of forest stability, the structure of natural water conservation forests is advantageous over that of plantations in the mountain areas of Beijing.
