在参考前人大量研究结果基础上,探讨中国森林生物量的空间分布以及植被地域性、年均温、年降雨量和海拔对森林生物量空间分布的影响。结果表明:我国森林生物量存在明显的空间分布规律,其值从东到西逐渐降低,总体分布规律呈东北地区>西南地区>南方地区;地域性植被和非地域性植被的森林生物量均表现为暖温带<寒温带<温带<亚热带<热带林;不同林分类型的森林生物量表现为落叶阔叶林<针阔叶混交林<针叶林<常绿阔叶林<热带林的规律;年均温和年降雨量是影响森林生物量的主要因素,森林生物量基本随年均温、降雨量的升高而逐渐升高;不同海拔梯度对森林生物量有着明显的影响,随着海拔升高森林生物量基本呈逐渐降低的趋势。

On the basis of reference of forefathers′research results,the spatial distribution of forest biomass in China as well as the regional vegetation,annual average temperature,annual precipitation and altitude on the influ-ence of the spatial distribution of forest biomass,in order to the sustainable development of forest resources in China and provide reference for operation and management.Research shows that:the spatial distributions of forest bio-mass obvious in our country,from the east side to the west are gradually reduced,and the overall distribution of China's forest biomass is northeast China >southwest China >the south region of China.the regional vegetation and the regional forest biomass of vegetation are characterized by warm temperate zone <cool <temperate zone <subtropical zone <tropical forest;different forest types of forest biomass of deciduous broad-leaved forest <needle broadleaf mixed forest <coniferous forest <evergreen broad-leaved forest <the law of the tropical forest.moder-ate average annual rainfall is the main factors influencing the forest biomass and forest biomass the basic with the in-crease of annual average temperature,rainfall and increasing gradually.different altitude gradient has a significant impact on forest biomass,with increasing altitude forest biomass basic trend of gradually reduce.
