本文在分析岷江上游干旱河谷区生态环境问题的基础上，阐述了该区生态退化是脆弱的自然生态环境和人类的不合理经济营活动综合作用的结果，指出生态恢复与重建必须与经济建设紧密结合，走生态经济发展之路，将岷江上游干温河谷区划分为干旱河谷粮果林生态我，中山，亚高山林药菌生态林业区，高山灌丛草甸，草甸生态特业区，并提出了不同的生态经济类型区的生态恢复与重建模式，最后，论述了生态恢复与重建的工程措施，生物措施及管理措施。

Based on analyzing the eco-environment problems in the arid-mild valley of the upper reaches of the Minjiang River, this paper describes that the ecological degradation in the region is resulted from the high natural fragility and intensive human-induced disturbance. During the course of ecological restoration and rehabilitation, the economical development should be taken into account. In order to instruct the eco-economic construction, the arid-mild valley is divided into three areas including that of grain-fruit-forest ecological agriculture in arid valley, that of forest-medicinal herb-fungus ecological forestry in mid-mountain and subalpine belt, and that of meadow thickets and ecological meadow pasture in alpine belt. Different measurements applied to them are suggested and the measurements of engineering, biology and management are discussed as well.
