摘要
概述了传统水土流失强度分级指标的适用范围及深圳市城市水土流失强度分级指标的局限性.指出了建立城市水土流失强度分级指标体系必须遵循的原则,据此,建立了包括土沙流失指标、水流失指标和相关指标的城市水土流失强度分级指标体系.在该分级指标体系中,首次设置了水流失指标,并全面分析了设置该指标的必要性和可行性.
Applied regions of gradation index for traditional soil and water loss intensity and limitations of gradation index for urban soil and water loss intensity in Shenzhen city were generally expounded. The principles for establishing gradation index system of urban soil and water loss intensity were put forward. On the basis of the principles, the gradation index system of urban soil and water loss intensity has been established, including soil and sand loss index, water loss index which was presented first time and correlated index. Specially, necessities and feasibilities about setting up water loss index were systematically analyzed.
