基于ArcGIS的农田灌溉用水监测系统设计

Design of farmland irrigation water monitoring system based on ArcGIS

为解决农田灌溉用水量统计困难与复杂的问题,开展了基于ArcGIS的农田灌溉用水监测系统设计。通过对灌溉泵站电量的测量,配合人工率定以电折水转换系数,从而准确地换算得到用水量,再采用Internet/GPRS网络相结合的传输方式传送到后台服务器,实现用水量、电量、水价的显示查询以及网络共享等功能,并通过在海安市灌区试点证明了该系统运行稳定与可靠,达到预期的功能和效果,可为水资源公报和统计用水量提供技术支撑。

In order to solve the difficult and complex problem of farmland irrigation water consumption statistics,a monitoring system and design of farmland irrigation water consumption based on ArcGIS was developed.Through the measurement of the electric quantity of the irrigation pumping station and the determination of the conversion coefficient of electricity consumption into water consumption by combining with thE-manual work,the water consumption could be accurately converted and then transmitted to the backstage server by the Internet/GPRS network.The functions of the display,inquiry and network sharing of the water consumption,electric quantity and water price were realized,and the system was proved to be stable by the experiment in the irrigation area of Haian City,which could provide technical support for water resource bulletin and statistical water consumption.
