摘　　要：集水区内不当之农业活动 ,加速集水区土壤流失及水库水质恶化。本研究利用数值地形模型 (DigitalElevation Model,DEM)、配合遥感探测 (Remote Sensing,RS)与地理信息系统 (Geographic Inform ation System s,GIS)等技术 ,撰写程序建立集水区农业非点源污染评估系统 ,探讨集水区农业非点源污染控制之成效。利用泥砂递移率与植生缓冲带区位检视集水区内之农业非点源污染源 ,划定集水区环境敏感区位 ,针对敏感区回收造林 。Improper agricultural activities accelerate soil loss and water pollution. An assessment system for agricultural non point source pollution estimation was developed in this study. Digital Elevation Model (DEM), Remote Sensing (RS) and Geographic Information Systems (GIS) couples with non point source pollution models were applied in the system to discuss the efficiency of non point pollution control in a watershed. Concepts of sediment delivery ratio (SDR) and placement of riparian buffer strips couples with the analysis of topography and hydrology for the watersheds of interest to classify the sensitive zone could effectively monitor and control watershed agricultural non point source pollution.
