陕北黄土丘陵区窑洞侵蚀产沙分析

Research on Sand Production by Soil Erosion of Cave Dwelling in Loess hills in Northern Shaanxi

本文研究因在陕北黄土丘陵区建筑窑洞和塌窑而引发的土壤侵蚀问题,对窑洞的侵蚀产沙时间、空间进行分析,指出产沙主要来自建窑和塌窑时,产沙堆积空间主要位于窑洞院子前缘斜坡和坍塌窑洞的洞口坡地上;认为建窑和塌窑的土壤流失系数是不同的,并分别测算了各自的流失系数。

The soil erosion and collapse of cave dwelling in loess hills in Northern Shaanxi were researched, times of sand-making and spaces of sand--producing of soil erosion of cave dwelling were analysed. Results show that sands come from building and collapsing of cave dwelling, and sand space mainly located front slope and entrance of collapsing of cave dwelling in the courtyard , soil erosion coefficients of building and collapsing of cave dwelling are considered to be obvious different, their soil erosion coefficients also have been calculated respectively in the paper.
