- Title:
- Impact of Climate and Characteristics of Surface Component Material on Soil Erosion and Sediment Yield in the Liudaogou Watershed
- Keywords:
- Liudaogou watershed; climatic elememts; surface component material; wind and water erosion
- 摘要:
- 在野外调查与试验研究的基础上，分析了六道沟及其相邻流域降雨、径流、气温、风力等气候因素及地面组成物质特征对侵蚀产沙的影响。认为暴雨强度大，疾风多、植被少，地面组成物质复杂松散，以及不良的土壤理化特性，是该区侵蚀产沙特别强烈的根本原因，该区的侵蚀具有复杂多样的特殊性，在时间与空间上差异较大，分布不均；地面物质粗、产沙量大、是粗沙的主要产区；掌握侵蚀特点，控制风沙直接入沟，入河及坡耕地的改造，防治沟头，沟壑崩塌，扩大草灌，发展多样性农业为治理重点。
- Abstract:
- On basis of field investigation and experimental research, impact of factors of climate of precipitation, runoff, temperature and wind etc and surface component material on soil erosion and sediment yield in the Liudaogou watershed and neighouring watersheds is analysed. It is considered that the key reason that soil erosion and sediment yield is severe intensity is big rainfall intensity, gale, few vegetation cover, loose component material of surface and bad physi-chemical properties. Soil erosion has characters of different types, and temporal and spacial distribution is not uniform. Coarse material of surface and big sediment yield is main source area of coarse sand. With the results, key control measures is that while soil erosion characteristics is mastered,pretecting wind sand directs into gully and river, sloping farmland is remaked, gully head andgully-wall slides, is prevented vegetation cover is increased, comprehensive agricultuer is developed.
