| 摘 要： | 土壤侵蚀是世界性的环境问题，通过对近年来黄土高原丘陵沟壑区土壤侵蚀研究成果的综合分析，详细论述了这类地区土壤水力侵蚀的类型与机理、土壤侵蚀的营力机制、主要影响因素及流域产沙的预报与防治。指出，实现土壤形成与流失、输运与沉积、“利”与“害”、侵蚀和保持的动态平衡，是土壤水力侵蚀研究的主要方向。

| Abstract: | Soil erosion is a global problem of environment.It indicated that if was a main research field in soil and water erosion to carry out the dynamic ballances between forming and loss, transferring and depositing "benefit" and "harm", erosion and conservation.According to comprehensive analysis on research result of soil erosion in loess hilly gully region at present, the type and mechanism effective factors predictive model controllable measures of water erosion and producing sediment in watershed were discussed in detail. |
