摘　　要：利用１１８块野外标准地资料，对晋东南石灰岩山地油松人工林进行了立地类型划分及生长评价。经分析坡向、海拔、土层厚度为影响林木生长的主导立地因子，３个主导立地因子共构成２４个组合立地，每个组合立地可视为一个立地类型，用最优分割法将２４个立地类型划分为４个立地类型组。在优势木与平均木树高相关分析的基础上，以椽材林木为标准。对４个立地类型组进行了林木生长评价与预测。The division of site types and appraisal of growth were studied with data from 118 sample plots on Chinese pine in the calcareous mountain areas,Shanxi Province.The main site factors on growth are elevation,soil depth and slop direction,which consist of 24 combined sites.Each combined site is thought of a site type.Using the optimization division mathod,the 24 combined site types can be divided into 4 groups of site type.The wood growth was appraised and forcasted by the standerd of rafter on the basis of the correlation analysis between superior and ordinary plant.
