内蒙古东部黄土低山丘陵水蚀规律的研究

Study on the Law of water and soil Erosion in Loess HiLL in the-East of Inner Mongolia

本文通过482个水蚀图斑资料,运用线性模型理论,对内蒙古东部黄土低山丘陵区的水蚀规律进行了研究,获得了下垫面各因素与水蚀量的数学关系模型。通过对其分析得出各因素对水蚀的影响程度及各土地利用类型在水土保持效益方面的作用大小。

In this paper,by using the information of 482 water erosion picture patches and adopting Linear model theory,the water and soil erosion processes in Loess hill and semiarid pastureland area in the east of Inner Mon golia were studied.The mathematical realtionship models between ground cover factors and water erosion amount were made Through analyses we got the influence value of every factor related to wa- ter and soil erosion and the water and soil conservation effects of various Land utilization methods.
