Abstract

Water resources carrying capacity is an important indicator for evaluating the sustainable use of regional water resource. It is very important to evaluate regional water resources carrying capacity from systemic perspective which was a benefit for scientific management of water resources and protection of regional ecological environment. A water resources carrying capacity grading system was established based on water resource-water ecology-economy and society system. Using grey entropy weight clustering method which could make full use of data information to quantitatively calculate the water resources carrying capacity of Henan Province from 2001 to 2020. The results showed that water resources carrying capacity in Henan was upward trend with the carrying capacity grade rising from class IV to Class I from 2001~2020, which indicates that the water resources carrying capacity had been improved significantly. There were some indicators including total industrial wastewater discharge, urban sewage treatment rate, irrigation water consumption per hectare of farmland and water consumption of ten-thousand-yuan GDP identified as the main influencing factors limiting the improvement of water resources carrying capacity in Henan Province by using obstacle degree function analysis.
