黄土地区水土保持专家系统试验研究

A TEST RESEARCH ON WATER AND SOIL CONSERVATION EXPERT SYSTEM IN LOESS REGIONS

黄土地区水土保持专家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.该系统可对黄土地区的土壤侵蚀进行快速预测、预报,并对综合治理和规划提出建议.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.

This paper presents the approaches and principles for building a Water and Soil Conservation Expert System (WSCES) in loess regions. The system can be used coding. The WSCES can be also used to store,update,inquire,search,analyse,process,display data and images, and to make map automatically. In addition,the system can be used to predict the soil erosion in loess regions precisely and quickly. Furthermore,several plans and decisions for comprehensively harnessing soil erosion can be obtained by consulting with the system,so that users can select a practical program from them for bringing the water under controllig and improving the soil. Moreover,the author makes a test research with the system on soil erosion in Yangdaogou gully of Wangjiagou Watershed in Lishi County, Shaanxi Province, and evaluates the results systematically.
