基于模型和3S技术的数字麦作系统的设计与实现

为了充分发挥和利用3S技术、生长模型和管理知识模型的优势,探索适合中国国情的精准农业关键技术集成方法及应用模式,以软件开发方法论为指导,充分结合小麦生长模型、管理知识模型和3S技术,应用ASP.NET和C#开发Web应用程序,建立了基于模型和3S技术的网络化数字麦作系统.该系统以品种、气候、土壤及生产条件等为基本输入,具有麦作区划、栽培方案设计、模拟预测、策略分析、动态调控、生长监测、精确麦作、生产力评价、病虫草害管理、智能学习、系统管理和系统帮助等功能.以江苏省部分县市的气象、土壤、品种和生产资料为基础,对本系统进行了初步测试与应用,表明该系统可为农业生产者、管理人员和科技人员提供麦作数字化和科学化的决策支持.

Design and Implementation of a Model and 3S-based Digital Wheat Farming System

To fully utilize the advantages of 3S(GIS,RS,GPS) technologies,crop growth simulation model and crop management knowledge model,and to grope into the integration method and application mode of key technologies in precise farming adapted to Chinese circumstance,a model and 3S-based digital wheat farming system was developed based on plentitude combination of wheat growth simulation model,wheat management knowledge model and 3S technologies.Guided by the methodology of software development,the system was programmed with the languages of ASP.NET and C#.By inputting the parameters of varieties,climate,soil and production condition,the system realized the functions of wheat farming zone,cultivation strategy design,growth prediction,strategy evaluation, dynamic regulation,growth monitoring,precision management,productivity evaluation,management of disease,insect and weed,intelligent learning,system management and system help.The case study of the system with the datasets in some eco-sites of Jiangsu province indicated that the system can provide digital and scientific decision supports in wheat farming for farmers,agronomists and researchers.
