摘　　要：水资源开发利用程度评估与分析研究对于区域水利规划和水资源管理具有实践指导意义。三江平原作为国家商品粮生产基地,具有保障国家粮食安全的重要作用,同时,水资源开发利用问题与供需矛盾也日益凸显。为了定量研究三江平原水资源开发利用状况与态势,运用基于变异系数和相对熵改进的TOPSIS方法,对研究区水资源开发利用程度进行了综合评价,并对1984-2011年研究区水资源开发利用程度变化特征及驱动因素进行了分析。结果表明:2011年三江平原水资源开发利用程度处于中等水平,东北部地区较高,西南部地区较低;2001年是三江平原水资源开发利用程度变化的时间节点,2001-2011年十年间三江平原一半以上分区的水资源开发利用程度发展至中等水平;地下水资源开发利用和农业灌溉是三江平原及其大部分分区水资源开发利用程度变化的核心驱动因素,鹤岗市、双鸭山市和佳木斯市是推动研究区水资源开发利用程度演变的主要分区;相比2011年,2017年三江平原水资源开发利用程度和关键驱动因素无明显变化。研究结果可为三江平原水资源可持续利用提供参考和借鉴。Assessment and analysis of water resources development and utilization level provide practical and significance guidance for regional water resources planning and management.Sanjiang Plain which is a national grain production base plays an important role in ensuring national food security.On the other hand,water resources development and utilization issues,and contradiction between supply and demand are prominent.To quantitatively study the status and situation of water resources development and utilization,the improved TOPSIS method based on variance coefficient and relative entropy was used to comprehensively evaluate the development and utilization of water resources in the study area.The change characteristics and driving factors of water resources development and utilization level in the study area from 1984 to 2011 were also analyzed.The results showed that the level of water resources development and utilization in the Sanjiang Plain was moderate while higher levels in the northeast area compared to southwest area.The change time point of water resources development and utilization level was found in the year of 2001 in the Sanjiang Plain.From 2001 to 2011,more than half subareas in the Sanjiang Plain developed to moderate level.The groundwater resource utilization and agricultural irrigation were the core driving factors for the development and utilization of water resources in Sanjiang Plain.Hegang city,Shuangyashan city,and Jiamusi city were the main subareas that promoted the utilization and development of water resources in the study area.Compared to 2011,the water resources development and utilization level and the key driving factors of the region had no fundamental changes in 2017.The research results can provide references for sustainable water resources utilization in the Sanjiang Plain.
