【摘要】：根据安徽省水资源公报数据,采用信息熵和均衡度方法对全省的用水结构变化特征展开了分析研究。研究结果表明:2006~2015年的10 a期间,安徽全省、省内三大流域和6个典型城市的用水结构总体相对稳定,部分年份有所波动,而且农业用水仍占据主导地位。受地理位置和气候等因素差异的影响,三大流域和典型地市用水结构变化特征也存在着差异,其中,长江流域用水结构与全省的变化特征基本一致,滁州市用水结构的均匀性低于全省的平均水平。相对于"十一五"而言,"十二五"期间的用水结构有所调整:即农业用水比重下降,非农用水比重上升,整体上是朝着更加均衡的方向发展。对安徽省用水结构演变特征的研究,可为安徽省"十三五"水资源管理和年度计划的制定提供参考和依据。
[Abstract]:Based on the data of Anhui Water Resources Bulletin, the change characteristics of water use structure in Anhui Province are analyzed by using the method of information entropy and equilibrium degree. The results show that the water use structure of three major watersheds and six typical cities in Anhui Province is relatively stable during the 10 years from 2006 to 2015, and the water use for agriculture is still dominant in some years. Under the influence of geographical location and climate, there are also differences in the water use structure of the three major watersheds and typical cities, among which, the water use structure of the Yangtze River basin is basically the same as that of the whole province. The uniformity of water use structure in Chuzhou is lower than the average level of the whole province. Compared with the 11th Five-Year Plan, the water use structure of the 12th Five-Year Plan period has been adjusted: that is, the proportion of agricultural water use decreased, the proportion of non-agricultural water use increased, and the overall development is towards a more balanced direction. The study on the evolution characteristics of water use structure in Anhui Province can provide a reference and basis for the water resources management and the formulation of annual plan in the 13th Five-Year Plan of Anhui Province.
