中文摘要	以广西平果县龙何生态重建示范区的石漠化山地复合生态系统为例,依据试验研究及专家咨询的结果,构建了一个基于自然子系统、社会子系统、经济子系统的评价指标体系,采用层次分析法对指标体系中各指标的权重值进行了分析,应用指数评价模型对石漠化山地复合生态系统进行综合评估.层次分析结果表明,植被覆盖率、人类活动强度、物种多样性、物质生活指数、石漠化程度、水土流失程度等指标的权重值较大,是石漠化山地复合生态系统的重要影响因子;指数评价模型的评价结果表明,石漠化山地复合生态系统的总体质量较差,但通过生态示范区建设,改善复合生态系统中的植被状况,改善农业生产条件和推广先进农业技术,提高系统中人类的生活水平,可以使复合生态系统中社会、经济、环境3个子系统的转运功能逐渐趋于协调,总体质量逐渐好转.
英文摘要	Taking the Longhe ecological restoration demonstration area in Pingguo County,Guangxi Auto-nomous Region as an example,on the basis of result examination and expert′s consultation,an index system was constructed,and each index’s weight value was analyzed by AHP.Using an index model the assessment of the rocky desertification mountain compound ecosystem was made.AHP analysis results showed that the weight values of vegetation coverage,human activity intensity,species diversity,material life index,rocky desertification degree,water and soil erosion degree were larger than other indexes,indicating that all these factors play an important role in the compound ecosystem.The index model assessment results suggested that the comprehensive quality of the rocky desertification mountain compound ecosystem was rather bad before constructing the ecological restoration demonstration area.The vegetation coverage,the agricultural production conditions and the living standard of human in the system were promoted after the ecological restoration demonstration area was constructed,the comprehensive quality of the compound ecosystem was improved,and the social subsystem,the economic subsystem and the environmental subsystem ran more efficiently.
