土地开发项目区地下水流向研究——以定边县堆子梁镇为例

Research on the Flow Direction of Groundwater in the Land Development Pro-ject Area: A Case Study of Duiziliang Town, Dingbian County

摘要: 本研究调查了定边县堆子梁镇土地开发项目区周边的11个井点的地下水埋深，绘制项目区周边的地下水水位等值线图，调查结果表明：半数以上的监测井地下水埋深在5 m以内，地下水埋深较浅；2020年测得的各井点地下水埋深与2019年相比均有所上升，上升幅度在1 m以内；堆子梁镇周边地下水的是由东北方向流向西南方向，并以八里河泄洪渠为界，以北项目区的地下水向西堆梁村汇集，以南项目区的地下水汇流至东南角的夏坑村。

Abstract: This study investigated the groundwater depth of 11 well points around the land development project area in Duiziliang Town, Dingbian County, and plotted the groundwater level contour map around the project area. The survey results show that more than half of the monitoring wells are buried within 5 m underground, and the buried depth of groundwater is relatively shallow; the groundwater depth of each well measured in 2020 has increased compared with 2019, and the in-crease is within 1 m; the groundwater around Duiziliang Town is from the northeast. The direction flows to the southwest and is bounded by the Bali River flood discharge channel. The groundwater in the north project area converges to Xiduiliang Village, and the groundwater in the south project area converges to Xiakeng Village in the southeast corner.
