地下水和我们人类生活以及生产建设有着密切的关系,而在自然生态平衡中,它又是一个重要的环境因素。合理开发利用地下水是一个很重要的问题。 (一) 黄淮海平原由黄河、淮河、海河及其支流的泥沙共同冲积而成。其中黄河对于大平原的塑造起了主导作用。地貌特征自西向东差异较大:山前平原分布着大小不等的扇形地,如黄河冲积扇、漳河冲积扇、滹沱河冲积扇等;中部为宽阔的冲积平原;东部为滨海平原及河流三角
Groundwater and our human life and production and construction are closely related, and in the natural ecological balance, it is an important environmental factor. Rational development and utilization of groundwater is a very important issue. (A) The Huang-Huai-Hai Plain is formed by alluvial sedimentation of the Yellow River, Huaihe River, Haihe River and its tributaries. The Yellow River played a leading role in shaping the Great Plains. Geomorphological features vary greatly from west to east: the piedmont plain distributes fan sectors of different sizes, such as the Yellow River alluvial fan, the Zhanghe alluvial fan and the Hutuohe alluvial fan; the middle is a broad alluvial plain; the east is the coastal plain and the river Triangle
