北京北部山区天然油松林与人工油松林比较研究

Compared study between natural and artificial Chinese pine plantations in the northern mountainous area of Beijing

基于α多样性和森林群落结构,对北京北部山区的天然油松林与人工油松林进行了对比分析,北京北部山区的人工油松林与天然油松林的物种组成及重要值相似性较高;天然油松林的α多样性与群落结构总体优于人工油松林;油松适合作为造林树种栽种于北京北部山区,但要注意控制种植密度和阔叶树种搭配。

Based on α - diversity and forest community structure, the natural pine forests was compared to artificial pine plantations located in northem mountainous part of Beijing. The pine plantation in this area was much naturalized, and it was similar to the natural pine forest in the part of species＇ compages and importance value. The α - diversity and forest community structure of natural pine forest was much better than that of pine plantation. Chinese pine is suitable for aforestation in northern mountainous part of Beijing, but it should pay attention to keep better plant density and scientific configuration of broadleaved trees.
