Evaluation of Water Environmental Carrying Capacity in Huaihe River Basin

Based on the theory of water environmental carrying capacity, Through the establishment of evaluation index system of water environmental carrying capacity and the application of vector norm method, the water environmental capacity level is evaluated in Huaihe River Basin and analyzed change trend of water environmental carrying capacity index. The results indicated that Huaihe River Basin water environment carrying capacity has tendency of increasing in 2004-2015, its water environment carrying capacity was varied from 0.01 to 0.06, but the water environmental carrying capacity is low. Research results can provide scientific theory and technical support for regions of Huaihe River Basin works out scientific measure to improve the water environment carrying capacity, so as to realize sustainable development strategy.
