摘要
研究建立土壤资源信息系统，实现土壤资源定位管理，是合理开发我国南方大面积红壤资源的前提。以浙江省红壤区为例，设计的省、县、农场三级管理层次的土壤资源利用与管理信息系统（ＵＭＳＩＳ）包括基础数据库和评价、规划、咨询三个主模型库，具有数字化输入、图象处理、数据库管理、综合制图、空间相关分析等功能。目前已建立的浙江省、衢州市和龙游县三个不同比例尺实验性系统，已初步完成了系统调试和运行，并应用于区域红壤资源的资源分类、适宜性评价、水土保持、农业开发分区等工作。另外，研究也表明商用ＧＩＳ软件和应用模型的有机链接仍然是当前ＧＩＳ二次开发较为现实的途径。
To establish a soil resources information system for site specific management is essential for rational development and utilization of wide spread red soil resources in southern China. Taking Zhejiang province as an example, the conceptual design of UMSIS (utilizing and managing soil information system) at province, county, and farm scales was made for multi purpose application. UMSIS consists of soil resource database and three model bases of evaluation, planning, and consultation. It also provides digitize, image processing, cartographic tools, and spatial analysis function. At present, the experimental UMSIS of Zhejiang province, Quzhou city and Longyou county was created using ARC/INFO and applied into many works, such as soil resources classification, soil suitability assessment, soil and water conservation, agricultural developing zones etc. Now the testing and verification of the system is nearly completed. In addition, the result shows the integration of commercial GIS software and applying model is still effective method of secondary development of GIS system.
