| 摘 要： | 本文阐述了应用遥感技术进行土壤侵蚀动态监测研究的机理，建立了我国南方地区土壤侵蚀程度解译标志。根据兴国县和岳西县三个时相的土壤侵蚀动态态监测图和调查统计资料分析表明，建国以来南方山地丘陵区土壤侵蚀的动态变化，基本上呈抛线形发展态势；江西、福建、湖南、广东等省的土壤侵蚀面积，均有明显下降趋势。

| Abstract: | This paper describes the mechanism of dynamic monitoring of soil erosion with remote sensing technology, and establishes the interpretation keys for soil erosion degrees in Southern China. Analytical results based on the dynamic monitoring maps of soil erosion at three historical periods and the investigation and statistic data from Xingguo and Yuexi counties showed a parabolical type change of soil erosion in the mountainous and hilly areas of south China. It has an evident decreasing tendency of the soil erosion area in Jiangxi, Fujian, Hunan and Guangdong provinces of China. |
