摘要
涞源盆地位于保定西部太行山区,干旱缺水一直是困扰当地经济发展和社会和谐的因素之一。通过水文地质调查,查明了涞源盆地构造主控下的南盆地、北盆地和片麻岩3个地貌分区及其由5组断裂构建的地下水网络,发现新构造以导水为主,老构造以阻水为主。对调查的102处泉进行分析后,将其归纳为侵蚀泉、断层泉、溢流泉和接触带泉四大成因类型。根据调查获得的涞源盆地西部缺水现状数据,结合盆地自然地理和水文地质条件,分析认为造成缺水的原因主要包括降雨时空分布不均、地形地貌切割不同、岩性差异和人为水质污染,因此提出了开展找水工程、建设分散型蓄雨池、规划厂矿废水废渣处理工程和控制消除人为污染源等处理措施,以缓解缺水现状。
The Laiyuan basin is located in the western Taihang Mountains of Baoding. Drought and water shortage has been one of the factors affecting the local economic development and social harmony in the Laiyuan basin. Through hydrogeological inves-tigations, the geomorphologic divisions including south basin, north basin, and gneiss and the groundwater network formed by five cracks were identified, which suggested that the new structure is mainly water conducting whereas the old structure is mainly water preventing. A total of 102 springs were also investigated and can be classified into four genetic types： erosion, fault,overflow,and contact zone springs. According to the water shortage status in the western Laiyuan basin and the natural geographic and hydrogeological conditions, the causes of the water shortage include the temporally and spatially uneven distribu- tion of rainfall, difference in topographic cutting, difference in lithology, and water pollution. Consequently, several measures were proposed to alleviate the water shortage status, including conducting groundwater exploration engineering project, building scattered rain storage pool, planning treatments of wastewater, and removing pollution sources caused by human activities.
