基于高分辨率影像的冲沟发育及其时空变化研究
Research on Development of Gully Erosion and the Space and Time Change Based on High Spatial-resolution Image
摘要
Abstract
Gully erosion is a serious environmental problem in the world. Its development is represented by the soil erosion which became worse. Gully erosion is a very important source of sediment. At present, the study on gully erosion is mainly concentrated on the small scale areas. This article selected a small basin in Qixia by GIS and RS, and had a quantitative research about the gully development in 10 years. Finally, we found that the area of gully erosion increased 13.3%, and the amount of gullies remain unchanged. At the different altitude, the gradient, the aspect and the land use, the development of the gully erosion had a different tendency. Under the various space and time change, the gully affected by the natural and anthropogenic influence each other. But the anthropogenic influence was stronger than natural influence. So in the future, we must pay special attention to adopt the appropriate cultivation way to protect gully erosion.关键词
