摘　　要：为了及时准确获取灌区需水量数据,利用ArcEngine和C#作为开发平台和语言,结合GIS和RS的数据分析与影像处理功能,开发灌区需水量计算的应用系统。系统以遥感热红外波段反演的不同农作物土壤体积含水率与灌区的土地分类影像为依据,并根据不同作物的灌溉制度设置计算参数,经过系统运算可以快速得到灌区灌溉需水量的大小。通过对陕西泾惠渠灌区实例数据的计算结果分析表明,系统具有动态监测和实效性,为指导灌区进行水资源优化配置和精准灌溉提供重要的基础数据。In order to timely and accurately obtain irrigation water demand data, using AreEngine and C # as a deVelopment platform and language, combined with GIS and RS data analysis and image processing functions, an application system of calculating water requirement for irrigation district is developed. The system is based on the soil water content of different crops and the land classification images of the irrigated areas by remote sensing thermal infrared band, and the calculation parameters are designed according to the irrigation system of different crops. Through system operation, the irrigation water demand of irrigation area can be obtained quickly. The results of case data of Jinghui irrigation district in Shaanxi Province show that the system has dynamic monitoring and practical effect and can provide important basic data for guiding irrigation area to optimize water resources allocation and irrigation.
