基于GIS的玉米种植环境气象特征信息提取系统

Maize Planting Environment Meteorology Feature Information Extracting System Based on GIS

借助SuperMap平台的GIS功能,利用.NET平台和C#语言,设计并实现了玉米种植环境气象特征信息提取系统,共包括原始气象数据预处理、空间气象信息提取、气象特征专题图制作和图形化显示4个功能模块,不仅能实现对大量气象数据的高效管理,更能方便地进行玉米种植环境气象特征信息提取,并借助GIS空间分析技术进行专题制图与相关的决策分析。该系统既可以为玉米种植户提供精确的玉米种植环境气象特征信息,又可为玉米种子企业各级管理者提供各种决策分析支持,对有效降低玉米生产风险具有重要的现实意义。实践应用表明该系统具有较好的实用性。

A maize planting environment meteorology feature information extracting system based on SuperMap＇ s GIS capabilities,.NET platform,and C# language was designed.The system comprises four functional modules：source data preprocessing,spatial meteorological information extracting,meteorology feature thematic map producing and graphical displaying.It can not only manage massive meteorological data effectively,but also extract valuable maize planting environment meteorology feature information and support some related decision-making with GIS spatial analysis technology.It can provide accurate maize planting environment meteorological information for farmers and various decision supports for relevant managers in seed industry,which is of practical significance in reducing maize planting risk.Our application results have shown good usability of the system.
