江淮分水岭地理内涵辨析

A Geographical Discussion on the Concept of Jianghuai Watershed

江淮分水岭,顾名思义,就是长江与淮河之间的分水岭。但在具体使用中,江淮分水岭具体指代的区域常存在认识上的不一致。针对此问题,本文从地理学视角对江淮分水岭概念进行了剖析。研究认为江淮分水岭概念有自然地理学意义上及人文地理学意义上的双重含义。自然地理学上的江淮分水岭即是指长江与淮河之间的分水岭,西北起始于黄河、长江、黄河三河交界处,经伏牛山、桐柏山、大别山、江淮丘陵,向东以长江北侧岗地为界延伸至东海之滨。人文地理学意义上的江淮分水岭是指在安徽省相关政府文件中提出的"江淮分水岭综合治理区"。二者在实际指代的区域上具有本质区别。针对一些文献中把"江淮分水岭综合治理区"简称为江淮分水岭区的现象,本文认为这具有一定的合理性。但必须要明确的是"江淮分水岭"与"江淮分水岭综合治理区"本质上是不同的概念,在某些场合必须严格区分。

Jianghuai Watershed is the watershed between the Yangtze River and the Huaihe River.But there exist different opinions in the literatures toward the exact area that this concept refers to.This paper addressed this problem.On a physical geography view,Jianghuai Watershed refers to the watershed between the Yangtze River and Huaihe River,which extends from the joint area of the Yellow River,Yangtze River,and the Huaihe River to the East China Sea through the Funiu mountain,Tongbai mountain,Dabie mountain,Jianghuai Hilly Area,north bank of the Yangtze River.On a human geography view,Jianghuai Watershed refers to ' Comprehensive Management area at Jianghuai watershed' in Anhui province.The physical geography term and human geography term on the Jianghuai Watershed are quite different,although there has close link between them.But for the convenience of making use,it is acceptable to replace the ' Comprehensive Management area at Jianghuai Watershed' by a shortened one 'Jianghuai Watershed'.
