摘　　要：以石匣小流域为研究对象,选取植被覆盖度、水土流失强度、土地利用率、治理度、人均收入与当地平均水平的比值等5个指标,采用模糊综合评价计算评价指标值,根据可持续发展指标临界值所确定的不同阶段的划分标准,得出评价结果。结果表明:1991年石匣小流域属于不可持续发展阶段;1999年该流域属于一般可持续发展阶段。Taking Shixia watershed as the research object, the vegetation coverage, intensity of soil and water erosion, land use ratio, control degree, the ratio of income per capita and local average were used to calculate the evaluation index value by fuzzy comprehensive evaluation method. Base on the standards established according to critical value of sustainable development index, some conclusions were got. The results showed that Shixia watershed belonged to unsustainable development stage in 1991 and sustainable development stage in 1999.
