| 摘 要： | 本文通过分析河北省的水准测量资料，揭示了河北平原的地面沉降情况。整个河北平原都存在着下降的趋势。在大范围的下降背景上，又分布着许多大大小小的沉降中心。这些沉降区多数都是以城市为中心，互相连成一片，下沉速度有逐渐加快的趋势。河北平原地面沉降的原因，除少数有构造运动的因素以外，绝大多数都是集中过量开采地下水造成的。

| Abstract: | In This paper, the ground subsidence situation of Hebei plain was studied by using the leveling data. It was discovered that the whole of Hebei plain show a descending tendency. On the background of a large-scale subsidence, there are many subsidence centers with different size. Most of the descending areas are centered in cities, connecting each other, and the descending rate shows an accelerating tendency.In addition to a tectonic factor in a few subsidence areas, the causes of the ground subsi dence of Hebei plain are mainly related to concentrated over-extraction of ground water. |
