湖北省农情遥感速报系统的设计与实现

DESIGN AND IMPLEMENTATION OF HUBEI CROP WATCH SYSTEM WITH REMOTE SENSING

及时、客观、准确地预测粮食产量,对于国家粮食政策的制定、价格的宏观调控、对外粮食贸易、国家粮食安全保障、种植结构调整等都具有重要的意义。介绍了利用遥感数据、统计数据、气象数据及实地调查数据等多源数据,在数据库平台的支持下,采用客户端/服务器(C/S)的系统架构模式,使用面向矩阵的程序语言IDL开发的湖北省农情遥感速报系统。该系统以县级区域为统计单元对湖北省主要农作物进行长势监测、种植面积估算、单产预测与粮食产量估算等。系统测试结果表明:系统速度快、稳定性强、结果准确可靠,可为湖北省的农业决策与粮食生产提供及时、准确的信息服务。随着野外地面实测信息对遥感监测结果的标定和检验,以及技术方法和遥感数据源的不断改进与完善,系统的精度和准确性将会不断提高。

Predicting the grain production duly,objectively and exactly has great importance to the constitution of grain policy,the control of food price and economic trade,the security of foodstuff,and the regulation of planting structure.This paper introduces the Hubei Crop Watch System with Remote Sensing,based on the remote sensing data,statistical data,meteorological data,field data and other data.The system utilized DBMS as the database platform,adopted the systematized framework of Client/Server(C/S),and it was developed by Interactive Data Language(IDL)with the character of orienting matrix.Hubei Crop Watch System consists of several components,including crop condition monitoring,crop acreage estimation,yield prediction,and grain production estimation.The system is fast with stable operations and high efficiency,and it can provide accurate and reliable results.Thus the system could provide reliable information services for agricultural decision-making supporting and grain production of Hubei Province。
