摘要
本文介绍的新方法，由八个实测项目和措施组成，具有简便、直观和省钱的特点。经南北方各地的实测结果表明，它有着为常规法远所不及的适应性和实用性，又有与常规法同等的准确性。这使它能够获得为建立流失量监测模型或修正ＵＳＬＥ因子算式所需的大量实测数据，作为实现县、省级土壤年流失量遥感监测的基础。新方法的实测结果还表明，植被或作物的有无，严重影响着流失量的大小，特别是红壤区。
The
new method of observing annual soil loss and its parameters is made upeofeight observing
items and means.It is audio-visal,economical,simple and convni-ent.The results observed in
experimental areas of southern and northern Chinashow that the new method has better
adaptability,more practicality and the sameaccuracy as conventional method.So,the new
method can obtain a lot of observingdata which can be used in creating models of monitoring
annual soil loss or revisingformulation of USLE erosion factors to realize monitoring annual
soil loss over pro-vince or county area by using remote sensing and GIS Meantime,the results
obser-ved by using the new method show that changes of annual soil loss are
seriouslysubjected to the cover degree of vegetation or crop,particularly in red soil regions.
