土壤侵蚀信息系统的结构设计

THE STRUCTURE DESIGN OF SOIL EROSION INFORMATION SYSTEM

本文介绍了黄土地区土壤侵蚀信息系统的建造原理与方法。分析探讨了土壤侵蚀各因子计算机自动提取的算法，以及土壤侵蚀预测模型的构造方法，并用灰色控制系统的原理确定了模型的参数。并以山西省离石县王家沟流域羊道沟为例进行了试验研究。

This paper presents approaches and principles for building Soil Erosion Information System(SEIS) in loess regions, discusses the method to extract soil erosion factors automatically using computer and the approaches to build prediction model of soil erosion. Also, the author determines parameters of the model with principles of gray controlling system.
