摘要随着我国城市化步伐的加快,城市水土流失达到了惊人的程度,对城市的生态环境以及可持续发展产生不利影响。通过分析探讨城市水土流失的成因及其特点,提出了防治措施,以期为城市水土保持的研究发展以及城市生态环境建设提供合理科学的理论依据和实践方法,同时提倡水土保持新技术在城市水土保持中使用。

AbstractWith the accelerating pace of China's urbanization, the soil erosion of urban has reached alarming levels, which has adverse effects on the ecological environment and the sustainable development of the city. The causes and characteristics of soil erosion in city were analyzed, the prevention measures were put forward, so as to provide a theoretical basis and practical approach for the development of science and the ecological environment of the water and soil conservation in urban areas, and advocate the use of new technologies in urban water and soil conservation.
