摘　　要：在当今社会迅猛发展的城市化热潮下,自然生态环境受到了巨大的冲击,城市正面临着水土流失问题的侵扰。文章着重论述了城市化对自然生态产生的不同影响以及水土流失对城市的危害,并以其他国家的城市水土治理手段为范例,对深圳湾及总体环境进行了合理的数据分析,认为水土流失有显性水土流失和隐性水土流失,而保持水土生态平衡是城市水土保持的基本要求。基于水土生态理论的城市水土保持归根结底地还是要解决好人与水的关系、人与土的关系、人与植被的关系并依此创造丰富多彩的水土生态文化,积累更多保护、适应和合理利用水土生态资源的传统、方式和经验,是人与自然和谐的基本保证,也是城市水土保持所要实现的目标。Under the wave of rapid urbanization nowadays, the natural ecological environment is under enormous threat, and the city is confronted with problems of water and soil erosion. This paper focuses on the different impacts urbanization has made on natural ecology and the hazards of the erosion of water and soil. Taking the treatment for urban soil and water in other countries, as examples this paper also carries out a reasonable data analysis of Shenzhen Bay and its general environment. Based on the analysis, the author believes that urban soil and water erosion has both explicit and implicit sides,and that maintaining the balance of water and soil ecology is the basic requirement of urban soil and water conservation. The author also thinks that urban soil and water based on soil and water ecological theory must come down to solving the relationships between man and water, man and soil, and man and plants, to create a rich soil and water ecological culture,and to gather experiences, methods and traditions of protecting, adjusting and utilizing the water and soil resource, which is the guarantee of the harmony between man and nature as well as the goal of urban soil and water conservation.
