摘　　要：为了更好地管理大豆的生长过程,以专家施肥模型为决策依托,以气候要素、土壤属性、品种特性等为基础,采用多层结构体系,遵循面向对象的设计原则,运用ATL和WebGIS技术构建了数字大豆栽培系统并应用于指导生产。结果表明:精确管理田块平均产量(7 136.6kg/hm2)较之常规管理田块(6 563.6kg/hm2)增产8.7%,新增经济效益达3 017元/hm2。结论:该系统具有较好的决策性和广泛适应性,可应用于指导生产。To be able to better manage soybean-growing process, the authors used an expert fertilization model for decision-making, based on the climatic factors, soil properties, species characteristics,and adopted object-oriented design principles,the WebGIS-based digital crop support system was build by using network development language and be applied to soybean production guidance. The results showed that the average yield（7 136.6 kg/hm2 ）was increased by 8.7% compared with the routinely managed field（6 563.6 kg/hm2 ）.The newly increased economic benefit was 3 017 Yuan/hm2 . The system has better decision-making and wide adaptability.It can be used in production.
