摘要
为准确合理的预测用水结构,利用信息熵的方法分析了抚河流域2010-2016年用水现状、用水结构及其演变特征。结果表明,抚河流域用水结构的主要特点是农业用水占主导关键作用,工业及生活用水所占比例不高;用水结构信息熵总体呈上升趋势,用水结构系统趋于稳定,但各市县信息熵增幅各有不同。通过用水结构驱动力分析发现,社会经济因子是抚河流域用水结构变化主要驱动力。
In order to reasonably predict the water use structure,the information entropy theory is used to analyze the status quo of water use,water use structure and its evolution characteristics and development trend from 2010 to 2016 in Fuhe River basin. The results indicate that agricultural water occupied the dominant position,and industrial and domestic water accounted for a small proportion in water structure of Anhui Province;that when the information entropy value increases,the water structure system tends to be more stable,but the growth rate of the information entropy is different in various cities and counties. When analysing the driving force,we found that the social-economic factor was the major driving factor of water structure in Fuhe River basin.
