摘  要：
水库蓄水长时间淹没和浸泡,致使水库消落带的植被几乎全部死亡,坡面土壤流失贻尽,岩石滑塌甚至造成山体不稳,引发滑坡等侵蚀。水库消落带不仅仅应算做水库建设的扰动面积,而且应算做破坏水土保持设施的面积,尤其在我国植被生长良好的南方地区。水库消落带破坏水土保持设施面积应该是正常蓄水位以下水库面积与未建水库前水面面积之差,面积大小可以采用面积量算法和简单估算法得到。

摘  要：
In the hydro-fluctuation belt of reservoir, long-time inundation and dipping lead to vegetation dying, soil loss, rock slide and collapse, and landslide, as well as destroyed mountains stability. The hydro-fluctuation belt of reservoir should not only be regarded as the disturbed area, but also the destroyed area of soil and water conservation facilities, especially in South China where vegetation grows well. The destroyed area is the difference between the surface area when the water level is below its normal level and the surface area before the reservoir construction. The area can be calculated by the measurement arithmetic and the simple estimate arithmetic.
