摘要
指出了冲沟侵蚀是一种重要的土壤侵蚀方式,干热河谷区的冲沟侵蚀不仅吞噬宝贵的土地资源,还会对流域生态安全产生严重威胁,因此深入开展冲沟侵蚀研究对于区域水土保持与生态恢复重建具有重要意义。从干热河谷冲沟侵蚀研究方法、冲沟形态特征、冲沟侵蚀的影响因素等方面,探讨了干热河谷区冲沟侵蚀的研究进展,同时展望了今后干热河谷区冲沟侵蚀的研究方向与重点领域。
Gully erosion is an important kind of soil erosion. Gully erosion in dry--hot valley not only consumes the valuable land resources, but also creates serious threat to the ecologicalsecurity of river basin. Therefore, soil and water conservation and ecological reconstruction are of great significance. This article gavean introduction to the re- search progress of gully erosion in dry--hot valley from research methods, morphological characteristics, controlling factors of gully erosion. It also pointed outthe study orientation for gully erosion in dry--hot valley.
