土壤分类是土壤科学综合研究水平的反映。本研究采用B/S系统架构,利用WebGIS以及相关的计算机技术,在中国1:100万土壤数据库基础上,以ArcIMS作为土壤地图数据发布平台,使用ArcSDE作为空间数据库引擎,采用关系数据库SQL Server 2000统一管理土壤空间数据和属性数据,建立了一个基于WebGIS的中国土壤参比查询系统,实现了GSCC到CST的“傻瓜式”参比。该系统按照参比出发点的不同,即基于单个剖面数据信息,或基于二个系统分类单元的空间分布特征,分三个子模块,分别为基于全国尺度、区域尺度(省级)和单个土体尺度,这样研究人员可以通过友好的交互性界面便捷地查询到尽可能精确的土壤分类参比数据。
Soil classification reflects level of the overall research in pedology. An intelligent inquiry system for reference between the Genetic Soil Classification of China (GSCC) and the Chinese Soil Taxonomy (CST) based on the 1:1 000 000 soil database of China, and the techniques of WebGIS has just been established recently. The system has a Browser/Server framework, ArcIMS as its soil map data releasing platform, ArcSDE as its spatial database engine, and relational database SQL Server 2000 as the tool for integrated management of soil Spatial and attribute data. Consists of 3 sub-modules based on national, regional (provincial), and pedon scales respectively, the system is designed to conduct reference of pedon data or between the spatial distribution features of 2 soil classification units in the 2 different classification systems. With the help of the said inquiry system, researchers interested are able to retrieve conveniently related soil classification reference information as detailed as possible.
