Several representative regions including humid subalpine area, arid valley and the adjacent recovery area and the plateau region of Minjiang riverhead were selected to study the soil nutrient and biodiversity change. Based on field vegetation investigation, soil sampling and analyses, Ecological effects of land use/cover in these regions were discussed. Also in corporation with the social and economic data, the recovery methods of different degraded region were put forward.

研究选取亚高山湿润区域，半干旱河谷区及其恢复区，岷江源头高原面区域作为重点，通过大量的野外植被调查，土壤采样分析，多元统计方法等研究典型区土地利用／覆被变化的生态效应；并根据社会经济资料和调查数据和土地覆被-土壤相互作用规律，提出了岷江上游生态恢复对策。
