黄土丘陵沟壑区土壤侵蚀专家系统试验研究

A TEST RESEARCH FOR FORMING SOIL EROSION EXPERT SYSTEM IN LOESS HILLS AND GULLIES

本文介绍了黄土丘陵的沟壑区土壤侵蚀专家系统的建造原理与方法.系统采用压缩编码方式存贮各种地学图形与遥感图象数据,具有效据与图象的存贮更新、查询检索、分析处理、图象显示和自动制图功能.该系统可对黄土地区的土壤侵蚀进行准确、快速的预测、预报,并对土壤侵蚀的综合治理,水土保持规划提出几种可行性建议供用户选择。用该系统对山西省离石县王家沟流域羊道沟的土壤侵蚀进行了试验研究,并对试验结果进行了系统评价。

This paper presents the approaches and principles for forming Soil Erosion Expert System(SEES)in Loess Hills and Gullies.The system can be used to store various data of geo-maps and re-mote sensing images in compressing encoding.The SEES can be also used to store,update,inquire,search,analyse,process,display data and images,and to map-making automatically.In addition,the system can be used to predict the modulus of soil erosion in loess area precisely and quickly.In or-der to harness soil erosion comprehensively and to plan water and soil conservation,users can consultwith the SEES to obtain several practical harnessing proposals for users to select.Moreover,the authormakes a test research for soil erosion in Yangdaogou Gully of Wangjiagou watershed in Lishi county,Shanxi province with the system.The author also evaluates the test results with systematic theories,ob-tains soil erosion data in each year,and various maps of potential soil erosion and comprehensive har-nessing plan maps of water and soil conservation.
