建立四川盆地水土保持监测“零”基准面(点)的探讨

从认知水土流失“零”基准面的理论出发,在大范围的地理尺度及大的时间跨度层面上,根据岩层及土壤在外力（水力、重力、风力等）作用下的自然规律,即高势能向低势能的迁移表现,提出建立最低的水土保持监测基准面（点）,扩大水保法调整的范围,从而减少近期和长期的水土流失趋势。

Discussion on Establishment of the "Zero" Base Level/Point for Soil and Water Conservation Monitoring in Sichuan Basin

This study is performed by understanding the "zero" theory of soil erosion base level/point at first. Establishment of the lowest base level/point for soil and water conservation monitoring in a wide range of geography dimension and in a great time span is suggested according to the law of rock layer and soil under the external forces (water power, gravity and wind power, etc.), namely the process moving from the high potential energy to the low potential energy. The theory helps to extend the scope of amendment to the Soil and Water Conservation Law, and reduce short-term and long-term soil erosion.
