黄土高原的黄土成因、自然环境与水土保持

The History Environment of Loess Plateau and Cause of Loess and Soil and Water Conservation

摘要: 我国的黄土高原是在特有的地质、地理、气候等自然环境条件下形成的,在不同的自然地理区域,其自然环境特征各异,并形成了类型各异的黄土。从黄土高原内部第四纪以来阶段性抬升的地质背景分析水土保持的着眼点,一是改变地表的抗蚀能力和对水分的保蓄能力,二是改变地表的坡度,减少水流的能量等。

Abstract: The loess plateau in china forms induced by conditions of the geology,geography and climate.There are discrepancy environment characteristic in diff erent natural area and forming different loess.The geological background of loes s plateau internal from the fourth age in rising makes clear a soil and water co nservation to stress chauying geologic strata against erosion ability and so on.
