根据近年来从事城市水土流失研究的实践和体会,提出了目前在城市水土流失研究中值得商榷和急需澄清的4个理论问题。(1)城市水土流失概念的界定;(2)通用土壤流失方程式(USLE)在城市水土流失研究中的适用性;(3)城市水土流失的强度分级;(4)由开发建设项目所塑造的地貌形态的概化。并提出了自己的观点,以期起到抛砖引玉的作用,呼吁加强城市水土流失理论方面的研究。
This article put forward four problems which are deserved to be discussed and clarified in research of urban soil and water loss. The first is that the concept of urban soil and water loss need urgently to be clarified; The second is the suitability that the universal soil loss equation when it is applied to researching urban soil and water loss; The third is that intensity classification of the urban soil and water loss; The fourth is that aspect and character of landforms shaped by constructing of the exploitation construction items. These questions are discussed the oretically, and individual unique viewpoints of the authors are put forward, appealing for strengthen theoretic study on urban soil and water loss.
