西十高铁对秦岭山区地下水生态环境影响研究
Research on Impact of Xi'an-Shiyan High-speed Railway on Groundwater Ecological Environment in Qinling Mountain Area
摘要
Abstract
The protection of the ecological environment in the Qinling Mountain area has received great attention from the government and society.In order to better protect the groundwater ecological environment in the Qinling Mountain area and support the construction of railway ecological civilization,a typical tunnel project of the Xi'an-Shiyan high-speed railway passing through the Qinling Mountain area was selected as the research object.Methods such as data research and analogical investigation were adopted to establish an impact model of groundwater drainage caused by engineering construction on the ecological environment of surface vegetation,and based on this model,an assessment of the impacts of groundwater drainage on the ecological environment of surface vegetation in the Qinling Mountain area was carried out.Meanwhile,the ecological environmental impacts of groundwater drainage on aspects such as drinking water source protection areas and karst landscapes were analyzed.The ecological environment impacts of groundwater drainage were analyzed from aspects such as the relationship of groundwater recharge,runoff,and discharge,and the formation mechanism of karst.The results showed that high-speed railway construction should avoid karst areas and major fault development areas in the region.Based on the relative positional relationship between the project and hydrological conditions,formation lithology,etc.,appropriate groundwater environment route selection effectively reduced the ecological environment impacts caused by project-induced groundwater drainage.This research is beneficial to the ecological environment protection of groundwater in the Qinling Mountain area and the construction of the Xi'an-Shiyan high-speed railway tunnel project,and it can also provide a reference for groundwater ecological environment problems in similar engineering constructions.关键词
