As the benefit subject of development and utilization of water resources,the water use proportion of water use sector will have a considerable effect on the evolution of the development and utilization of water resources structure.Taking Anhui province as an example to analyze the present situation of water resources,use the data from year 2000 to 2011,in Anhui Province,analyzes the present situation of the water use of the water use sector in Anhui province.Then taking 2008 as the base year,simulate the water use structure from the year 2012 to 2020 by system dynamics model,and observe the changes of water structure. Simulation results show that industrial water,agricultural water and living water increased significantly from year 2012 to 2020,agriculture water is still the large Department,then to analyze the interaction mechanism economic development.%利用用户的220V低压电力线作为通信载体，不用布线、接口多、覆盖范围广、连接方便的PLC宽带通信技术的出现，可以作为解决目前电能表集抄模式中存在问题的一种最佳通讯方式。本论文项目的研究为电力公司未覆盖光纤的小区实现自动远程抄表和智能家居应用提供了解决方案，为智能电网的研究提供了参考。
