通过对河北省太行山区油松人工林100块临时标准地资料的数量化分析,得出了影响油松人工林高生长的主要立地因子是海拔高度、基岩母质、坡向,而土层厚度、有机质含量对其影响则不显著。我们利用海拔高度、基岩母质、坡向和土层厚度划分了26个立地类型。通过打分的办法,对各种立地类型作出了Ⅰ、Ⅱ、Ⅲ、Ⅳ级评价,得出油松应种植在立地级为Ⅰ、Ⅱ级的各类型上的结论。
Based on the quantitative analysis of the data of 100 temporary plots of Pinus tabulaeformis plantation in Taihang Mountain area of Hebei Province, it is concluded that the main site factors affecting the height growth of Pinus tabulaeformis plantation are altitude, basement matrix and aspect, while soil thickness , Organic matter content of its impact is not significant. We use the altitude, base rock matrix, slope and soil thickness divided 26 site type. By means of scoring, I, II, III and IV grades were evaluated for various types of site types, and the conclusion that Pinus tabulaeformis should be planted on each type of site I and II was established.
