摘　　要：根据对不同地形（主要指地带、坡向）处的森林类型差异，建立的２４个观测点，历时两年的实验观测资料统计分析，说明了冻土区域内森林地带土的冻结与林分类型的相互影响作用及林木生长发育与气温、地温、土融化层深度的依存关系。Twenty-Four observation points were set up according to various forest types in different terrains(band and direction of scope).Interaction between stand types and freezing of soil in forest terrain of frozen ground,and relation between forest growth and climate,soil temperature and depth of melting layer of soil were illustrated through two years observation.
