| 摘 要： | 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。

| Abstract: | This paper research and divide systematically vertical zone in the loess plateau by measurement rill erosion and shallow gully erosion in field, aerial photo interpretation,and large scale mapping etc..We divide the soil erosion into 3 zones in the hilly regions e.g.Liang-Ta zone,loess filled old valley zone,and present valley zone.In the plateau area,we divide erosion zone into 5 zones:That is plateau top(or flat Liang top or wide Ta top) zone,interim zone of plateau top and plateau slope, plateau slope zone,plateau slope foot erosion and accumulationalternative zone and present valley zone.And some sub-zone we have divided. We find a special zone which was neglected before e.g.rill and shallow gully interim zone.And,we advance a new concept of mixed zone of shallow gully and gully.This is very useful for soil erosion mapping: and arranging conservation measure. |
