摘　　要：国家尺度土壤信息系统的建立对于全国和区域的土壤学及相关学科的研究具有重要意义。本研究收集长期积累的各种土壤图和土壤属性图资料,利用WebGIS技术,以ArcIMS作为土壤地图数据发布平台,结合相应的数据库技术,建立了中国土壤信息查询系统。系统分为4个部分,分别提供了全国土壤的类型分布、基本属性、养分元素含量和微量元素含量在多个尺度下土壤信息的查询。系统提供的SQL查询功能可以根据用户的研究需求灵活地构建查询表达式进行查询,区域查询功能则可以查询在全国和各个行政区域内土壤类型或土壤性质的各个类型或等级(含量)分布的总面积及其占该行政区域面积的百分数。用户可以通过友好的交互性界面便捷地查询到尽可能多的土壤信息。Construction of a countrywide Soil Information System is important to the study of soil science and other disciplines relevant to soils of the country or regions. Using ArclMS as a soil map data releasing platform coupled with relevant database technologies, a WebGIS-based China Soil Information Inquiry System has been established on the basis of various soil maps and soil attribution maps accumulated in the past years. The Inquiry System is divided into 4 parts, which provide information on classification distribution, basic properties, concentrations of nutrient elements and trace elements of the soils of the country at a variety of scales, respectively. Its SQL query function helps users to build up query strings flexibly according to their needs in the study. Its regional query function provides information about total areas and percentage of each soil in area, based on type or class at a national or provincial scale. With the help of the above-mentioned inquiry system, users interested in this system are able to retrieve conveniently related soil information as detailed as possible.
