安徽省地貌分区和分类

安徽地貌单元可分为区、亚区、形态成因类型和微地貌４级。全省有：１）淮北平原、２）江淮波状平原、３）皖西山地、４）沿江丘陵平原和５）皖南山地５个地貌区，包括１５个地貌亚区。根据４ｋｍ２内的最大高差划分了地貌形态类型。安徽省内平原、丘陵、山地均有，以平原为主。平原占全省总面积的６２％。考虑外营力种类ｈ作用方向，以及地貌发育历史，在安徽境内划出：１）堆积、２）堆积－剥蚀、３）堆积－侵蚀剥蚀、４）剥蚀－堆积、５）剥蚀侵蚀、６）侵蚀溶蚀和７）侵蚀７种地貌成因类型。

GEOMORPHOLOGIC DIVISION AND CLASSFICATION OF ANHUI PROVINCE

Geomorphological units of Anhui province may be divided into four classes :geomorphic regions ,subregions ,land form-genetic types and dimmutive relief. There are 5 geomorphic regions which contain 15 subregions in Anhui province : 1)plain on the north bank of the Huaihe River, 2)undulational plain between the Changjiang (Yangtze)River and Huaihe River,3)mountains in the western Anhui , 4) hill and plain along the Changjiang River ,and 5)mountain in the southern Anhui. Geomorphologic types are divided by the maximum relief volume within 4km2. There are mountains, hills and plains in Anhui province ,and the dominant one is plain which covers 62% of the whole area of Anhui. Considering the kinds of exogenic forces,thier directions and history of geomorphic development, seven geomorphologic genetic types are concluded as 1) accumulational, 2)accumulation-denudational,3)accumulation - erosional and denudational, 4) denudation - accumulational ,5) denudational and erosional , 6)erosional and karst and 7)erosional.
