摘　　要：基于网格系统抽样法对494块样地调查和已有各类生物量模型统计,系统研究了广东省阔叶林生物量的分布格局.结果表明,广东省阔叶林的平均生物量为76.82 t/hm2,处于偏低水平;全省阔叶林生物量在不同经济区和流域空间尺度分布严重不均;生物量与纬度、海拔的升高成正比关系,人类活动的干扰对阔叶林生物量的影响已经超出了气候条件影响;阔叶林的龄组结构、层次结构以及郁闭度结构与生物量之间有较大的相关性.Based on the grid systemic sampling method and the biomass models, the distribution patterns of broadleaved forest biomass in Guangdong were studied. The results showed that the average biomass of Guangdong broadleaved forest is relatively low, only 76. 82 t/hm^2 ; Biomass was unevenly distributed on different economic regions and different drainage area. The biomass showed similar trend with latitudinal and altitudinal change, and human activity had more effect on the distribution of biomass than climate. The age structure, hierarchy and crown density show close relationship with biomass.
