摘　　要： 采用相对资源承载力的研究思路与计算方法,计算1986—2002年珠江流域相对土地资源承载力、相对经济承载力和综合承载力及其变化过程。研究表明:①珠江流域人口承载力从1986—2002年一直处于超载状态,经济资源成为珠江流域的主要承载资源;②相对资源承载力区域差异明显,广东省综合承载力一直处于富余状态;云南、贵州和广西承载力一直处于超载状态;中上游地区自然资源是主要的承载资源;下游地区经济资源是主要的承载资源;③上游地区生态环境恶化,下游地区人地矛盾日益突出是珠江流域可持续发展中存在的主要问题;④珠江流域经济带的建设意义重大。 This paper uses methods of relative carrying capacity of resources. The relative carrying capacity of land resources, relative carrying capacity of economic resources and synthetic carrying capacity of resources of Pearl River drainage area have been calculated from 1986 to 2002. Thus conclusions were drawn: ①The economic resources is the principal resources to support population and the synthetic carrying capacity has been the state of overload from 1986 to 2002.②The relative carrying capacity is very different in this region, the synthetic carrying capacity of Guangdong has been the state of relative enough from 1986 to 2002;the synthetic carrying capacity of Yunnan, Guizhou and Guangxi has been the state of over load from 1986 to 2002. The natural resources is the principal resource of the middle resource and upper reaches of Pearl River drainage area. The economic resources is the principal resource in lower reaches of Pearl River drainage area.③The ecologic environment of upper reaches has become bad and the contradiction between human and environment system so lower reaches becomes various, which are the main problems its way to wards the sustainable development direction.④It is very important to construct Pearl River drainage area economic belt.
