【摘要】 采用压力—状态—响应评价法对 1 990～ 2 0 0 1年广西国有林场森林生物多样性进行了研究 ,发现林场森林生物多样性十多年来呈下降趋势。导致森林生物多样性减少的主要根源是林场人口急剧增长和不当的森林经营方式。提出了控制人口增长、转变森林经营方式以遏制林场森林生物多样性减少、保护森林生物多样性的对策更多还原

【Abstract】 The method of press-state-echo from 1990to 2001,has been used to study forest biodiversity in this paper. By analyzing the forest biodiversity changing,the downtrend is found out in the forest biodiversity on State-owned Forest Farms in Guangxi. There are two main reasons in reducing the forest biodiversity,one is that the population rises sharply on state-owned forest farms and the other is that improper forest management system has been carried out in the past decade. Reducing population and changing forest management system are good methods in preventing forest biodiversity from downtrend.更多还原
