摘　　要：通过对不同热量带主要森林群落营养元素循环的研究，结果显示：热带、亚热带的季雨林、山地雨林和常绿阔叶林养分积累量多，循环速率高，温带地区森林的养分积累慢，循环速率低。This paper studied the main forest community nutrient cycling in different thermalzones. The results showed that The nutrients accumulation and rate of nutrient cycling is high in monsoonforest, montane rain forest and broad - leaved evergreen forest of tropical belt and subtropical belt, and thenutrients accumulation and rate of nutrient cycling is low in temp- erate zone.
