摘　　要：针对吉林省白城地区具有洪水资源利用的地区优势,利用系统论中信息熵的概念分析该地区洪水资源利用前后对用水结构演变的影响.结果表明:白城地区地下水利用中,农业用水占用水总量的比例最大(1995—2009年比例均值为88.2%),而洪水资源利用后,洪水的水量补给使其比例降低至87.0%,弱化了用水结构的单一性,提高了用水结构的信息熵.洪水资源的适度利用有利于用水结构向合理化发展.Based on the regional advantage of floodwater utilization in Baicheng region,Jilin Province,the information entropy and equilibrium degree were introduced to discuss the trend of water consumed structure evolution. For Baicheng region,the agricultural water consumption accounted for a larger proportion in the conventional groundwater utilization,for which the average proportion was88. 2% from 1995 to 2009. But the floodwater utilization weakened the oneness of water consumed structure,such as floodwater supply reduced the proportion of agricultural water consumption to 87. 0%,therefore enhanced the information entropy. The sound evolution of water consumed structure was forced by floodwater utilization.
