摘要:
[目的] 定量研究2008—2017年江西省水资源利用时空变化特征以及各项水资源指标的区域差异,为水资源可持续利用提供参考依据。[方法] 基于2008—2017年江西省自然、社会经济以及水资源资料,利用变差系数、泰尔系数和空间分级分类法,从时间维度和空间维度分析了江西省2008—2017年水资源时空分布特征,并采用“竹笋”七色差异评价法对江西省各项水资源指标的区域差异进行研究。[结果] 南昌市2008—2017年水资源开发利用相对处于一个较高的水平,年均水资源开发利用率达到46%,处于不健康状态,而整个江西省平均开发利用率不到25%,水资源状况呈现健康的状态;江西省2008—2017年工业用水和农业水量分布差异较大,11市的生活用水和总用水空间分布差异较小;江西省2008—2017年人均水资源和地均水资源区域差异的差异值小于380,处于“竹笋”七色模型的稳定区,2008—2017年期间波动小。[结论] 整体来看江西省各市水资源禀赋差异性较大,要综合多个因素,深度剖析各个地区的水资源各类指标,比如人口数量、气候、环境、地形、文化差异等,因地制宜,才能使水资源真正为社会经济的可持续发展服务,达到人与水环境的协调统一。

Abstract:
[Objective] The spatiotemporal variations and regional indicator differences in water resource use in Jiangxi Province (from 2008 to 2017) were analyzed in order to provide alternative references for the efficient and effective utilization of water resources.[Methods] Based on environmental, socioeconomic, and water resource data of Jiangxi Province from 2008 to 2017, the spatiotemporal variations and regional differences in water resource use in Jiangxi Province were analyzed by using variation coefficients, Theil coefficients, a spatial classification method, and the seven color difference evaluation method of “bamboo shoots”.[Results] The development and utilization of water resources in Nanchang City from 2008 to 2017 was at a relatively high level, with an average annual water resource development and utilization rate of 46%, which was classified as an unhealthy state. The average water resource development and utilization rate of Jiangxi Province was less than 25%, which was classified as a healthy state. The distribution of industrial water and agricultural water in Jiangxi Province was quite different from 2008 to 2017, whereas the spatial distribution of domestic water and total water in 11 cities was relatively less different. From 2008 to 2017, the regional difference values of per capita water resources in Jiangxi Province was less than 380, which was in the stable area of the seven color “bamboo shoot” model. During 2008—2017, the data fluctuation decreased and the data of each city became more stable.[Conclusion] In all, there were great differences in water resource endowment in Jiangxi Province. It is necessary to analyze many water resources indicators, including population, climate, environment, terrain, and cultural difference, in order to promote sustainable development of the overall socioeconomic situation, and achieve the hamony and unity of man and water enviroment of Jiangxi Province in the future.
