旅游活动对岩溶地下水水质动态变化的影响——以重庆金佛山水房泉为例

Study on the effect of tourism activities on dynamic variation of karst groundwater quality:a case study of Shuifang Spring,Jinfo Mountain,Chongqing

为了更好地揭示岩溶地下水的影响因素,采用野外现场实测、自动观测、实验室分析相结合的方法,在"十一"旅游旺季对重庆金佛山水房泉流域各项理化指标进行连续监测。监测结果表明,岩溶地下水对外界条件反应敏感,其岩溶水理化性质容易受外界条件的影响,自然因素和人为因素的改变,可直接快速地改变地下水水质。旅游季节地下水水质发生明显变化,旅游因素对地下水质的变化有较好的响应关系。表现为旅游高峰前期的正常水平;旅游高峰期的骤然恶化,出现污染状况;旅游高峰后期,叠加降雨因素的影响从而使各个水质指标出现好转。

The physicochemical characteristic of the Shuifang Spring,Jinfo Mountain,Chongqing during National Day holiday were continuously monitored by the combination method of field measurement,automated monitoring and laboratory analysis.Base on the obtained data,dynamic characteristics of karst groundwater quality and its influencing factors were investigated.Results showed that the karst groundwater quality was highly sensitive to external environment,and it could be influenced by both natural factors and human activity factors.The groundwater quality had a better response to tourism activities,the water quality index were in the normal level before the peak of tourism activities,they presented a sudden increase during the peak of tourism activities,and then water pollution appeared.In end of the tourism activities,combining the factor of rainfall,the water quality index finally dropped back to the normal level.
