[Objective] Studying on the classification of geomorphologic types in Huaihe River Source to provide reference for land use

tourism

urban planning and biodiversity conservation in this area.[Methods] Taking Huaihe River source as an object of study

adopting the representative landform classification scheme in the Chai Zongxin scheme

Xu Hanming scheme and Gao Xuanyu scheme

using neighborhood analysis

reclassification

map algebra

and conversion tools in spatial analysis

the geomorphologic types of Huaihe River source were classified under each scheme and compared with the actual survey terrain based on the DEM data with a resolution of 30 meters so as to find the most suitable scheme for the basic morphologic classification of the Huaihe River source landforms.[Results] The Chai Zongxin scheme is single factor and can not reflect the basic features of the geomorphology. Gao Xuanyu scheme did not proved its advantages fully in the two grade classification for the study area

as it is more suitable for the area with high elevation and complex landform. The Xu Hanming scheme is based on 2 conditions

both relative height and altitude

that is to say

objective effect and subjective feeling of height were considered for basic morphologic classification of the geomorphology. Therefore

the Xu Hanming scheme is more suitable for the division of geomorphology in Huaihe River Source.[Conclusion] According to the Xu Hanming scheme

the geomorphic form of Huaihe River Source region was divided into 4 types:plain

hilly

low mountain and middle and low mountain

it is mainly covered by plain and hill

is low in the east and the north part and high in the west and the south part.
