摘　　要：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.
