摘　　要：为了促进江西省灌区技术现代化及灌溉用水管理现代化的发展,为实时灌溉决策提供较为精确和及时的作物需水量预报数据支持,开发了江西省逐日水稻需水量预报与网络发布系统。系统通过关系型数据管理系统MySQL来获取水稻需水量预报模型计算所需的参数及基本信息,分别使用率定了的Hargreaves-Samani(HS)模型、Blaney-Criddle(BC)模型、McCloud(MC)模型和作物系数来预测江西省未来7天26个气象站点的作物腾发量ETc值。用户可登陆网址查询任意站点、任意水稻生长阶段、任意模型预报的ETc数值,页面简洁,易于操作。总体而言,率定后的4种模型均具有较高的预报精度,可用于全省的水稻需水量预报,为灌溉决策和节约灌溉用水提供科学依据。To promote the development of technology modernization and irrigation water management modernization in Jiangxi Province and provide more accurate and timely crop water demand forecast data support for real-time irrigation decision-making, this paper develops a daily rice water demand forecast and web-based release system in Jiangxi Province. The system uses the relational data management system MySQL to obtain the parameters and basic information required for the calculation of the rice water demand forecast model by using calibrated Hargreaves-Samani(HS), Blaney-Criddle(BC) and McCloud(MC) models, and crop coefficient to predict the ETc value of crop evapotranspiration at 26 meteorological stations in Jiangxi Province in the next 7 days. Users can login to the website to check ETc forecasts for any site, any stage of rice growth, and any model. The website page is simple and easy to use. In general, the four calibrated models have good forecast accuracy and can be used to forecast the water requirements of rice in the whole province, laying a scientific foundation for irrigation decision-making toward water saving.
