摘要
通过构建亳州城市化发展与水资源利用的指标体系,利用熵值法确定指标权重,分别评价2003—2017年亳州市城市化和水资源利用综合水平的发展变化,在此基础上构建耦合协调度模型,分析亳州市城市化与水资源利用的耦合协调关系。结果表明:亳州城市化综合指数整体呈上升趋势,特别是2010年以后综合指数的增幅明显加快,是人口城市化、经济城市化、社会城市化、空间城市化过程综合作用的结果;水资源利用水平变化起伏较大,2003—2011年整体呈现趋势性下降,2011年以后表现出趋势性上升,主要受水资源量等要素的影响;城市化与水资源利用的耦合度2003—2009年呈现波动上升,增加幅度大,2009—2017年耦合度整体处于相对平稳阶段,有小幅波动;耦合协调度不断提高,从2003年的中度失调阶段发展到2017年的良好协调阶段。
By constructing an index system of the urbanization and water resource utilization in Bozhou city and using the entropy method to determine the index weights,the development and changes of the comprehensive urbanization and water resource utilization in Bozhou city from 2003 to 2017 were evaluated respectively.Based on this,a coupling coordination model was built to analyze the relationship between urbanization and water resource utilization in Bozhou City.The results show that the comprehensive urbanization index of Bozhou shows an upward trend on the whole,and an obviously accelerating trend after 2010,as a result of the comprehensive effects of population,economic,social and spatial urbanizations.The water resource utilization fluctuates greatly,showing a general trend of decline from 2003 to 2011,and a trend of rise after 2011,which is mainly affected by the amount of water resources and other factors.From 2003 to 2009,the coupling relation between urbanization and water resource utilization fluctuated greatly,while from 2009 to 2017,the coupling was relatively stable and fluctuated slightly.The coupling coordination level has been continuously improved,from the moderate imbalance stage in 2003 to the better coordination stage in 2017.
