摘要
中梁山位于重庆市的近郊区,是净化城区污染空气,调节主城区气候环境的重要地带。渝合高速公路隧道横穿中梁山,破坏了地下水的循环过程,引起泉水和地表水的枯竭。水源枯竭面积7.2 km2。隧洞每年渗漏水量283.9万m3,有21个泉(井)受到影响,其中17个泉(井)完全干枯,有5口堰塘全年都无水可蓄。造成4个自然村、748户居民、2 247人失去了饮用水,143 hm2耕地失去灌溉用水。
The Zhongliang Mountains, located in the suburb region of Chongqing, play a very important role in regulating climate, improving environment and cleaning polluted air of the city proper. However, the excavation of a tunnel through the mountain on the Yu-He Highway has changed the circulation of the local underground water resources and resulted in the losses of water. An investigation has revealed that an area of 7.2 km^2 has been affected, where water sources are exhausted in 17 spring wells and reduced in 21 spring wells, and 5 ponds are dry the year round due to the lack of feeding water. The total loss of water due to the tunnel amounts to 2 839 000m^3 per year. As a resuh, 748 households with a population of 2247 in 4 natural villages have no drinking water and 143.3hm^2 of farmland have no water for irrigation.
