摘要

地理信息系统(GIS)方法在空间单元要素数据的附加、处理和采集方面发挥着重要作用。特别是通过图形处理和空间数据操作的有机结合,空间重叠分析解决了自然元素到行政评价单元的划分。随着GIS在作物适宜性分析中的应用技术的不断提高,以及计算机网络的迅速发展,WebGIS应运而生并成为一个热门话题。现有农业地理信息系统向网络化方向发展是必然趋势。本文阐述了基于WebGIS的河南省作物适宜性分析系统的技术和方法,同时对系统的需求分析、结构设计、数据库设计与数据组织、种植适宜性分析、系统实现等方面进行了详细的介绍。

Study on the Crop Suitability Analysis System Based on WebGIS in Henan
Geographic information system(GIS) methods play an important role in attaching, processing and gathering the elements’ data of the spatial units. Especially, through combined the graphics processing and the spatial data operation organically, the spatial overlapping analyst resolved the division from natural elements to administrative evaluate units. With the steady improvement of the application technology using GIS to the crop suitability analysis, and the rapid development of computer network, WebGIS has emerged and become a hot topic. It's a certain trend that the existing agricultural GIS will develop in the direction of network.. The paper described the techniques and methods about the Henan crop suitability analysis system based on WebGIS, and at the same time, make an elaborated introduction of the requirements analysis of the system, structural design, database design and data organization, planting suitability analysis, system implementation, etc.
