Abstract

Based on the relevant data of nature, society, economics and water resources of eight sub-areas of Taihang Mountain from 2016, this paper selected six main evaluation factors including use efficiency of water resources, water deficient ratio, irrigation ration of arable land, precipitation amount of precipitation, per capita water resources and ecological water use ratio, and quantitatively researched water resources carrying capacity of eight sub-areas by using the fuzzy comprehensive evaluation method. The evaluated results show that the comprehensive grade of the study area was higher than 0.614, and the current water exploitation and utilization have reached a considerable scale, but still has certain potentiality. Overall, water resources supply and demand are able to partly satisfy the regional development in the the study area. For the eight sub-areas, the water resources carrying capacity status is very different. Handan, Xingtai and Shijiazhuang have a weak water resources carrying capacity, while water resources carrying capacity of other sub-areas is relatively strong. Finally, according to different regions of the water resources carrying condition, this paper puts forward the corresponding measures in Taihang Mountain Area.
