摘　　要：以典型半干旱黄土丘陵区固原上黄试区为例,回顾1982—2005年综合治理的经验。采用农民参与式农村评估方法(PRA),对上黄试区生态建设的成果进行分析。结果表明:上黄试区生态建设及经济建设成效显著,社会经济发展水平呈稳定增长态势,人均年纯收入从研究初期的94.4元增长到"十五"期间的2093.2元,土壤侵蚀模数从研究初期的6000 t/(km2.a)减少到现在的1000 t/(km2.a),生态环境得到了明显的改善。说明半干旱黄土丘陵区采用这种发展模式是有效的。Taking Shanghuang experimental area as an example, the experiences of comprehensive harnessing experiences from 1982 to 2005, with the method of Participatory Rural Appraisal（PRA） were reviewed, and the ecological, economical, and social benefits of ecological construction were analysed. The results show that ： the ecological, economical, and social benefits of ecological construction increased steadily. The average annual income of per farmer increased from 94.4 Yuan to 2 093.2 Yuan during the studied period. The eco-enviroment was improved obviously, the soil erosion module decreased from 6 000 to 1 000 t/（km^2·a）. It is suggested that the rural economic development pattern should be adapted to semiarid hilly area of the Loess Plateau.
