基于Arc Engine的茶叶生产气象服务业务系统的设计与实现

Design and Implementation of Arc Engine-based Agrometeorological Service System for Tea Production

为适应茶叶生产发展的需求和提高气象为特色农业服务的能力,以现有茶叶气象服务技术及研究成果为基础,基于C/S软件架构,利用Arc Engine作为开发平台,结合C#语言、SQL Server数据库以及网络技术,研制了浙江省茶叶生产气象服务业务系统,并投入业务应用。系统主要包括数据管理、小气候监测、灾害监测预警、农用天气预报、气候品质评价、气候适宜度分析、茶园可视化监测、农业气候区划、产品制作、基础知识等10大功能模块;系统集成了茶叶精细化气象指标、预报评价模型和GIS空间插值技术,在时间上可以开展未来1~8天滚动的预警预报,在空间上可以制作乡镇级或5 km×5 km网格级的服务产品;通过与省内气象数据库的无缝对接,确保了系统的智能化运行。系统不仅在浙江省级气象为农服务中应用,而且已在茶叶主产市县中推广应用,实现了浙江茶叶气象服务的定量化和精细化。

For adapting to tea production development needs and promoting the ability of weather service foragriculture, agromete orological service system for tea production in Zhejiang was developed by C/S softwarearchitecture and Arc Engine-based platform, combining with tea meteorology theory, C# language, SQL Serverdatabase and network technique. Thus, the system was applied in Zhejiang Province. It included 10 functionalmodels, namely data management, micro- climate monitoring, disaster monitoring and early- warning,agriculture weather forecast, climate quality evaluation, climate suitability analysis, tea garden visualizationmonitoring, agricultural climate regionalization, production making and basic knowledge. Owing to the refinedtea weather index, prediction or assessment model and GIS technique, the system could predict daily in thenext 1-8 days with spatial resolution of town unit or 5 km×5 km grid. Furthermore, the system could operatedynamically in real-time by linking to the Zhejiang meteorological database. The refinement and quantificationof meteorological service for tea production was not only applied in Zhejiang Province, but also promoteda cross the main tea producing cities and counties.
