摘 要:本文用约1000块标准地资料,系统地研究了内蒙古大兴安岭兴安落叶松林(Larix gmelinii Rupr.)的立地质量评价。在重温各种立地质量评价方法的基础上,从广义数学模型出发,探讨了地位级和地位指数的实质。进而编制了大兴安岭落叶松人工林,中、南部和北部天然林以及石塘林等四个地位指数表。为便于宏观管理和立地质量比较,同时编制了地位指数级表。并在分析林型—地位指数级—地位指数三者关系的基础上提出立地质量评价系列化的设想。Site quality of Larch (Larix gmelinii Rupr. ) in Great Xing' an Mountain in Inner Mongolia was studied systematically with about 1000 temporary plots and computer software. The natural of site class and site index curve was discussed in view of generalized mathematical model of height growth. The height growth of dominant tree of four kind of forest stands were studied and site index tables were constructed respectively. In order to unify the comparing standard and convenience for management in this region, site class table was constructed too. Based on discussing the action and accuracy of forest type, at last, a series of site quality evaluation (forest typesite index class-site index) was suggested.
