基于RIA WebGIS的区域烟草精准施肥管理决策系统设计与实现——以攀枝花烟区为例

Design and implementation of decision-making system for tobacco precision fertilization in Panzhihua tobacco growing area based on RIA Web GIS

以数据为基础的传统Web GIS存在共享性弱,伸缩性差,开发难等弊端。RIA/REST的应用能显著增强系统响应能力,简化GIS Service过程。本文在根据区域土壤肥力差异、供肥性能和肥料利用率等建立施肥模型、案例库、专家知识库及施肥决策方案的基础上,利用Flex API+REST API+SQL的RIA Web GIS框架构建了攀枝花烟草生产施肥管理决策系统(http://218.89.168.145:8080/webgis1/),实现了农田、作物生产信息管理和智能化施肥决策的集成,以及快捷高效的在线访问。结果表明,系统可为用户提供科学合理的施肥方案,施肥量得到更精准控制,且RIA/REST开发框架具有部署灵活、开发简易、伸缩性强等特点,用户体验和交互性更具优势。

The use of traditional data-based WebGIS is restricted due to weak scalability, poor sharing and development difficulty. The use of RIA and REST can enhance GIS interactivity and simplify service processes. Fertilization model was set up according to soil fertility difference, soil nutrient supplying capacity, and utilization rate of fertilizers. Decision-making system of Panzhihua tobacco production and fertilization management was developed through RIA Web GIS development framework based on Flex API＆amp; REST API＆amp; SQL in combination with well-established data library, expert knowledge base and fertilization scheme. . With high degree of coupling between crops production and intelligent fertilization decisions, the system achieved quick and efficient online access to information. Results showed that this system could provide farmers with scientific and rational fertilization program. The development framework of RIA/REST showed more flexibility in deployment, simplicity in development and strong retroactivity.
