摘　　要：以WebGIS为空间信息管理平台,通过有效耦合油菜生长模拟模型和管理知识模型,运用软件工程思想,采用多层体系结构,建立了基于模型和WebGIS的网络化数字油作系统。系统以品种遗传参数、气候要素、土壤理化特性和生产条件等为基本输入,具有系统管理、种植区划、方案设计、生长预测、动态调控、策略评估、精确栽培、生产力分析、病虫草害管理、智能学习、信息管理和系统帮助等功能。以江苏省部分县市为案例区,对系统进行了测试和应用,结果表明该系统可为油菜种植提供数字化和科学化的油菜管理决策与咨询。Based on the principle of software engineering and multi-layer systematic structure,and with WebGIS as the platform of spatial information management,a model and WebGIS-based digital farming system in rapeseed was developed by integrating the simulation model for growth prediction and knowledge model for management in rapeseed. With cultivar genetic characteristics,weather data,soil physical and chemical properties and farming condition as the basic input parameters of system,the system realized the functions as system management,planting zoning,prescription design,growth prediction,dynamic regulation,strategy evaluation,precise cultivation,productivity analysis,disease-pest-weed management,intelligent study,information management and system help,etc. Case study of the system was carried out in some eco-sites of Jiangsu Province,and the results indicated that the system could provide digital and scientific decision-making and consultation on rapeseed management.
