| 摘 要： | 黄河三角洲地区地下淡水（微咸水）资源贫乏，咸水广布。南部冲洪积平原受第二次海侵层位的影响形成大面积咸水，后被逐渐淡化。近年来由于开采量加大，又使北部咸水南侵。海积冲积平原随着黄河河道的变迁，仅在黄河现行河道两侧和充水的黄河故道带分布有淡水（微咸水）。近代，现代黄河三角洲古河道带和决口扇淡水体已被咸化。

| Abstract: | Ground fresh water (brackish water) is short in the Yellow River Delta. The second salt water intrusion formed a large area of saline water in the southern alluvial plain, which has gradually become fresh water. However, due to overpumping of groundwater, the northern saline water has moved to the southern area. As a result of the change in Yellow River course, fresh water (brackish water) can only be found on the sides of the river course and along the old river course in the sea alluvial plane. The fresh water has been salted along the Yellow River Delta old course and crevasse splay. |
