本文讨论了山西省油松天然林分布的范围、水平分布和垂直分布的特点及其与一些生态因子的关联。应用主分量技术,以生态条件为主对山西省油松自然地理区的划分进行了探讨,划分出北部区(包括东北亚区和中北亚区)、中部区和南部区三个自然地理区。为我省油松种子区划奠定了生态学基础。
This paper discussed the distribution, distribution and vertical distribution of natural Pinus tabulaeformis forest in Shanxi Province and their correlation with some ecological factors. The main component technology was used to discuss the division of the natural geographical area of Pinus tabulaeformis in Shanxi Province. The three natural geographical areas were divided into the northern area (including Northeast Asia and North Central Asia), the central area and the southern area.
