摘要：
Taking Kuitun River Basin, a typical arid inland river basin in Xinjiang, as the research object, on the basis of determining the space-time scale of watershed health assessment, the evaluation index system covering water resources health, water related ecological environment health and socio-economic health was proposed, and the watershed health assessment model based on combination weighting and coordinated development degree model was constructed. The results show that the sub healthy areas in 2015 are subregion 1, subregion 2, subregion 3 and subregion 6, whose comprehensive evaluation indexes are 0. 419, 0. 404, 0. 408 and 0. 401, respectively. The type of coordinated development is critical coordinated development. The subregions in unhealthy state are subregion 4 and subregion 5, whose comprehensive evaluation indexes are 0. 358 and 0. 343, respectively. And the type of coordinated development belongs to moderate uncoordinated recession type. © 2020, Editorial Board of Water Resources Protection. All rights reserved.
