| 中文摘要: |
| 研究区位于沙松乌拉山前托拉海冲洪积扇区,区内沉积了厚度较大的第四系松散沉积物,其岩性主要为卵砾石、砂砾石及砂层。含水层厚度大于50 m,为赋存地下水提供了良好的空间场所。该区因降水稀少,蒸发量大,松散岩类孔隙水主要接受托拉海河水的下渗补给,主要河水补给来源于托拉海东沟、西沟,其中托拉海西沟年平均流量较小。洪积扇中前部地区地下水位埋深一般为20～65 m,水量较丰富,水质较好。 |
| 英文摘要: |
| the study area is located in the tora sea alluvial proluvial sector in front of shasongwula mountain. Quaternary loose sediments with large thickness are deposited in the area, and the lithology is mainly gravel, gravel and sand layer. The aquifer is more than 50m thick, which provides a good space for the occurrence of groundwater (Yang Guilin, 1996; Zhang Jingxian, 1996; Liu Yonghong, 1998). Due to the lack of precipitation and large evaporation, the pore water of loose rocks is mainly supplied by the Torre sea water, which is mainly supplied by the East ditch and the West Ditch of the Torre sea, and the annual average flow of the West Ditch of the Torre sea is relatively small. The buried depth of groundwater level in the middle and front of the alluvial fan is generally between 20-65m, with abundant water and good water quality. |
