土壤侵蚀垂直分带是黄土高原土壤侵蚀分布的重要规律。本文通过野外细沟、浅沟侵蚀实测,航片判读和量算,小区域调查与制图等方法,对黄土高原土壤侵蚀垂直分带作了系统研究和划分,并提出两个水土保持重点带。通过系统的测量发现了以往被忽视但很重要的一个侵蚀带:细沟、浅沟侵蚀过渡带。提出浅沟、切沟侵蚀混交带的新概念。本文对塬区与丘陵区分别进行研究与划分,补充了塬区分带研究这一薄弱环节,对黄土高原土壤侵蚀制图和水土保持措施布设具有指导意义.
Vertical zonation of soil erosion is an important rule of soil erosion distribution in the Loess Plateau. In this paper, the vertical zonation of soil erosion in the Loess Plateau was systematically studied and divided by field measurement of thin furrows, shallow trench erosion, aerial interpretation and measurement, small area investigation and cartography. Two key water and soil conservation zones were proposed. A systematically measured and previously discovered, but important, erosion zone has been found: thin rift, shallow trench erosion transition zone. Proposed a new concept of shallow ditch, ditch erosion erosion belt. In this paper, the study on the Loess Plateau and the hilly area were separately made, which supplemented the weak link in the study of zoning on the Loess Plateau and provided guidance for the mapping of soil erosion and the arrangement of soil and water conservation measures on the Loess Plateau.
