| Abstract: |
| Based on the data of water resources, society, economy and ecological environment in Jiangxi Province from 2004 to 2018, by constructing a comprehensive evaluation model of regional water resources carrying capacity, this paper evaluates the water resources carrying capacity of Jiangxi Province, and discusses its spatial and temporal distribution characteristics. The results show that: （1）The regional distribution of water resources in Jiangxi Province is uneven, the carrying pressure of water resources in Nanchang is the largest, and that in Jiujiang is the smallest, but the overall difference is not obvious. （2）From 2004 to 2018, the carrying pressure of water resources in Jiangxi Province showed a downward trend, and the development and utilization of water resources showed a benign development state.（3）In 2018, the water resources carrying capacity in Nanchang, Pingxiang and Yingtan was on the verge of overloading, but in all other regions of Jiangxi Province was appropriate, so the development of social economy in Jiangxi Province has moderate pressure on water resources, and the development and utilization of water resources still have great potential. The research results be able to provide decision basis for water resources planning and rational development and utilization in Jiangxi Province. |
