摘　　要： 利用森林资源清查资料和经过实地校正的相关森林生物量和生产力估算方程,对珠江三角洲森林植被的生物量和生产力进行了研究。结果表明,珠江三角洲森林的生物量为132 404 963 t,总净生产量为26 273 769 t.a-1。区域森林生物量主要分布在珠江三角洲的外围,其中,马尾松林和常绿阔叶林的生物量占区域森林总生物量的52.18%;生态公益林的生物量只到达用材林的48.68%;中幼龄林生物量所占比例很大,总体质量不高,但如果现有森林得到更好地保护和管理,珠江三角洲地区的森林会有较大的发展潜力,并在维护区域生态环境上起着主导作用。 Forests inventory database and the regression equations for biomass and productivity of forests which were improved by investigations on forest vegetation in Pearl River Delta were proposed in this paper, and forest biomass and net production in the Pearl Delta were estimated. The results indicate that the biomass of forest biomass in Pearl River Delta is 132 404 963 t, gross net production 26 273 769 t.a^-1. Regional forest biomass mainly distributes on the verge of Pearl River Delta, among which the biomass of Pinus massoniana and evergreen broadleaved forests is 52.18% of the gross amount. Biomass of ecological protective forests is accounted for only 48.68% of logging forests. For biomass of medium and young-aged forests have a very big proportion, the quality of regional forests is not good. However, if better protection and better management are carried out for forests now, there would be greater developmental potential for the forests in Pearl River Delta and lead a major role in maintaining regional ecological environment.
