黄河冲积扇对中原城市群的地质控制作用

The geological control of the Yellow River Alluvial Fan on Central Plain cities

黄河冲积扇是中国中东部山前地区最大的冲积扇,其主体位于河南省。黄河冲积扇的形成发育的地质环境条件,冲积扇的地层岩性结构、水文地质特征,以及与其相邻地貌单元的地质和资源条件共同决定了中原城市群各城市的分布、发展规模、发展方向、产业结构等要素。通过黄河冲积扇的形成演化和本身地质、水文地质条件研究,从地质角度分析和探讨了中原城市群城市可持续发展的有利条件和影响因素,旨在为中原城市群的规划、建设提供地质科学依据。

Yellow River alluvial fan is the largest alluvial fan in the piedmont region of east-central China,and its major part is located in Henan Province.The distribution of the Central Plain cities,their development scales and directions,and their industrial structures are jointly determined by the formation,the geological environment,the stratigraphic and lithologic structure and the hydrogeologic characteristics of the Yellow River alluvial fan,as well as the geologic conditions and resources in adjacent geomorphic units.By studying the formation and evolution of the Yellow River alluvial fan,and its geologic and hydrogeologic conditions,we discussed the advantages and influencing factors concerning the sustainable development of Central Plain cities,in order to provide scientific evidence for the urban planning and the reconstruction of the Central Plain cities.
