Abstract Applicable, operative and simplified indicator system frame for sustainable development of Puwa small watershed comprehensive management was brought forward. This indicator system was composed of goal layer, category indicator layer, item indicator layer, and indicator variable layer, totally including 16 concrete indices. Small watershed sustainable development degree was used to describe the sustainable development ability and level of its comprehensive management. It was composed of social development capacity, economic development capacity, and resource and environment carrying capacity. Social development capacity was composed of material demand degree and core development degree. Economic development capacity was reflected by economic wealthy degree. Resource and environment carrying capacity was composed of resource richness degree and environment endurance degree. According to the sequence from indicator variable layer, item indicator layer, category indicator layer to goal layer, every indicator value in every layer was calculated out, the indicator value of sustainable development degree of small watershed comprehensive management was eventually computed by using the data from Puwa typical small watersheds under the direction of sustainable development theory. Puwa small watershed sustainable development in different years was scientifically evaluated and analyzed.
