摘　　要：以安徽省各地级市为研究对象构建城市化综合评价体系,并以熵值法对该区域综合城市化水平进行评价,同时基于生态足迹理论对水资源利用效率进行量化,创新性地验证了城市化水平与水资源利用之间的相互关系。研究发现:安徽省城市化水平可分为4个阶段,其中合肥市城市化水平最高;2018年安徽省水资源生态足迹总量为4724亿hm^(2),农业用水生态足迹占比最高,其次为工业用水生态足迹;水资源生态足迹总量随着城市化发展呈现急剧增长,然后缓慢下降,最后缓慢增长的变化趋势;随着城市化的不断发展,水资源利用效率不断提高,水资源生态压力先增加后缓慢降低。研究结论为安徽省城市水资源可持续发展提供决策支持。In order to demonstrate the correlation between urbanization level and water use efficiency,the study used Prefecture-level cities in Anhui Province as its objects,an evaluation system was constructed and the entropy method was used to evaluate comprehensive urban development level,the water resources ecological footprint model was used to calculate the water use efficiency.The results are as follows:16 Prefecture-level cities in Anhui Province could be divided into four grades,of which Hefei was at the highest level of urbanization;The total water resources ecological footprint of Anhui Province was 472.4 billion hm^(2),of which the water resources ecological footprint of agricultural production accounted for the highest proportion,followed by the industrial production;With a continuous urbanization,the total water resources ecological footprint showed a trend of rapid growth,slow decline,and finally slow growth;With the advancement of urbanization,the water use efficiency would continue to increase.The ecological pressure of human social and economic activities on water resources firstly increased and then slowly decreased.Based on these results,suggestions were put foeward for sustainable development of water resources in Anhui Province.
