中国土壤信息共享研究——1:400万中国土壤分布式查询数据库

SHARING OF SOIL INFORMATION DATA DISTRIBUTED INQUIRY DATA BASE OF 1:4M SOIL INFORMATION OF CHINA

基于INTERNET网络的信息高速公路的开通,为土壤资源信息网络化和共享提供基础条件,从而避免低水平的重复投资、重复建设,充分发挥土壤信息在国家建设、农业发展、生态环境保护、资源合理利用、科学研究和国内外同行学术交流中的作用。本研究利用当前世界上最流行的客户端/服务器,分布式查询的网络通信模型,以标准化的土壤信息为基础,采用先进的 Web GIS、ASP和Frontpage等网页编辑和发布技术去达到并实现 1:400万中国土壤空间信息和属性信息的分布式动态查询、静态查询和远程用户进行图形查询与编辑的目的。通过本项目的研究为促进中国土壤信息的标准化、规范化和网络共享提供了理论与方法论。

Information high way based on INTERNET is the foundation for sharing of soil information data sharing. It avoids unnecessary repetition of investment and construction, and brings soil information into full play for economic construction, agricultural development, environment protection and rational use of natural resources. To reach the targets of dynamic, static and remote distributed inquiry of soil map and attribute data, a client/server distributed network inquiry model and the techniques of Web GIS, ASP and FrontPage have been used and developed for this research. The study of this paper provides theory and methodology for further standardization and sharing of soil information data in China.
