皖江城市带经济差异与其自然地理成因分析

The research on Wanjiang city belt economic differences and physical geography characteristics

通过2001～2006年的城市经济统计资料的对比,得出皖江城市带的流域经济特征:一是区段性,皖江段处在长江流域经济的低谷,巢湖"大湖经济"不突出;二是差异性,皖江城市带内部发展不平衡,存在东西差异和南北差异,具有流域空间分异特征;从自然地理要素角度来看,断裂、地形地貌差异、洪灾差异、冲洪积平原面积差异以及区域自然地理特征对现代交通布局和航运的影响等是造成皖江城市带经济差异性的自然原因。

Compared with urban economic statistical datas from 2001-2006, economic characteristics of the Wanjiang city belt are obtained. The first is section. Wanjiang section occupies the Yangtze＇ s basin economic slump,＂ the Lake economy＂ of Chaohu is not prominent. The second is difference. The developments of Wanjiang section＂ s interior city don＂ t balance, exist East-West difference , North-South difference and basin spatial variation features. Judging from physical geography elements, fracture, differences of the terrain, the geomorphology, the flood, the aggraded flood-valley plain area as well as characteristics of the regional physical geography impact on modem transportation and shipping are natural reasons that cause economic differences of Wanjiang city belt.
