摘要
贵州省黔南布依族苗族自治州(简称黔南州)岩溶十分发育,生态环境脆弱,这对公路养护提出更高的要求。由于生态脆弱,岩溶山区公路养护不当可能引发环境污染和生态破坏。一是对路域植物生境的破坏,二是对水环境和环境空气的污染,三是对地下水渗流场的改变。本文结合岩溶山区公路养护存在的生态问题,提出环境保护技术措施,这对岩溶山区普通国省干线公路绿色养护具有一定的指导意义。
Qiannan Buyei and Miao Autonomous Prefecture of Guizhou Province(Qiannan Prefecture for short) has a very developed karst and fragile ecological environment, which puts forward higher requirements for road maintenance. Due to the fragile ecology, improper maintenance of roads in karst mountain areas may cause environmental pollution and ecological damage. The first is the destruction of plant habitats in the road area, the second is the pollution of water environment and ambient air, and the third is the change of groundwater seepage field. This paper puts forward technical measures for environmental protection in combination with the ecological problems existing in road maintenance in karst mountain areas,which has certain guiding significance for the green maintenance of ordinary national and provincial trunk roads in karst mountain areas.
