摘　　要：岩溶山区生态环境脆弱,在岩溶山区城市发展进程中,城市生活污水对岩溶地下水系统影响较大,生活污水往往成为岩溶山区城市地下水污染的主要来源。尤其在老旧小区,污水管网破损常见,生活污水渗漏现象点多面广,污染扩散速度快,治理难度大。本文以贵阳市某岩溶泉域为研究对象,通过溯源调查、地下水示踪试验、污染监测等方法对地下水污染开展溯源排查。查明地下水污染通道,揭示地下水污染污染成因模式,并提出源头控制的治理模式,治理成效显著,为岩溶山区城市地下水污染溯源及治理提供了经验和借鉴模式。The ecological environment in karst mountainous areas is fragile.During urban development in these regions,domestic sewage significantly impacts karst groundwater systems,often becoming the primary source of groundwater contamination.In older residential communities,damaged sewage pipelines are common,leading to widespread leakage of domestic wastewater.This results in rapid pollution diffusion and substantial governance challenges.This study focuses on a karst spring catchment area in Guiyang City.Through source tracing investigations,groundwater tracer tests,and pollution monitoring,the research identifies groundwater contamination pathways,reveals the mechanisms of pollution formation,and proposes a source-control governance model.The implemented measures have achieved significant governance outcomes,providing valuable experience and reference models for tracing and managing urban groundwater pollution in karst mountainous regions.
