摘　　要：根据我国红壤资源的分级管理及其目标不同的原则 ,设计研制了由省级 (1∶ 5 0 0 0 0 0 )、市级(1∶ 2 5 0 0 0 0 )和县级 (1∶ 5 0 0 0 0 ) 3个比例尺组成的红壤资源信息系统 (RSRIS) .系统集成采用动态链接结构 ,以 GIS图形控件为技术开发支撑 .并基于关系型数据库 ,以面向对象连接方式将应用模型无缝地嵌入到 RSRIS系统中 .Red soil is a very important soil resource in southern parts of China. But being existing simultaneously of enormous productive potentialities and severe soil degradation it needs harnessing urgently. Red Soils Resource Information System (RSRIS) of Zhejiang province (1∶500 000), Quzhou city (1∶250 000) and Longyou county (1∶50 000) made by means of GIS respectively plays an important role in surveying, evaluation, utilization and management of red soils resource. Dynamic linking structure was adopt to integrate three scales RSRIS to an comprehensive system supported by Mapobject OCX (ESRI). Particular emphasis focused on developing applied models that were embedded in RSRIS based on relational database. Plant utilization zoning model was taken a sample to show procedure of applied modeling.
