摘要: 以主要造林树种生物学特性与立地因子的协调性为立地分类的依据.借助聚类分析法对立地生产性能的相似性进行数量化描述,以欧氏距离定义立地单元间的相似性,类重心法计算类间距,在一定的相似性水平上划定立地类型。研究地区共划分为12个类型,编制了立地类型表,并采用热量、水分、养分三段式命名法为备立地类型命名。落叶松和油松在12个立地类型上的生长预测结果与现有林生长状况基本一致。

Abstract: In north Taihang Mountain, Shanxi Province, the forest site of water reservoir forest subregion in Wutai Mountain were classified and evaluated by the cluster analysis method. On the basis of biological characteristics of main tree species harmoniziog with site factors, similarities of site production property were discribed quantitatively by the cluster method. According to the results, the region was classified into 12 site types at a fixed similarity level, which were named by three-section name method (heat, water and nutrient). The results of growth forecast of Larix principis-rupprectii and Pinus tabulaeformis at 12 site types were coordinate with the growth status of the existing forest.
