摘要
研究区域用水结构变化对于区域可持续用水以及水资源合理配置具有重要意义。本文选取江西省2011-2020年水资源量以及用水数据,运用信息熵理论研究江西省用水结构变化规律。研究结果显示:(1)2011-2020年江西省多年平均水资源总量为1703.17亿m^(3);(2)近十年来江西省用水总量总体呈下降趋势,其中工业以及农业用水量总体呈下降趋势,生活、城镇公共以及生态环境用水量呈增长趋势;(3)近十年江西省用水结构信息熵和均衡度总体处于增长状态,全省用水结构进一步完善。
It is of great significance to study the change of regional water use structure for regional sustainable water use and rational allocation of water resources.In this paper,water resources and water consumption data of Jiangxi province from 2011 to 2020 are selected to study the change rule of water consumption structure in Jiangxi province by using information entropy theory.The results show that:(1)the average annual total water resources from 2011 to 2020 is 170.317 billion m3;(2)In recent decade,the total water consumption in Jiangxi province shows an overall downward trend,whose industrial water consumption shows a downward trend,while the domestic water consumption,urban public water consumption and ecological environment water consumption shows an increasing trend;(3)In recent decade,the information entropy and equilibrium degree of water use structure in Jiangxi province are increasing,and the water use structure in Jiangxi province is further improved.
