STUDY ON THE DYNAMIC CHANGES OF SPRING FLOW, CONDUCTIVITY AND pH VALUE
-
摘要:
岩溶水是指赋存于岩溶孔隙中的地下水，是我国南方生产生活主要用水来源.随着社会对水资源需求的逐步扩大，岩溶水资源的开发利用越发重要.通过定期监测岳麓山泉水流量、电导率、pH值，结合岳麓山岩土层性质和长沙市降雨量，采用统计分析和Spearman秩相关系数法对泉水流量变化和泉水水质定性评价进行研究.研究结果表明，大气降雨对岩溶水进行补给从而使泉水流量增大，泉水流量的改变除与降雨量有关外，还受土壤入渗率和降雨时长的影响.采用Spearman秩相关系数法可定量计算电导率与时间的相关性，间接判断周围环境对泉水水质影响的难易程度，有利于识别电导率代表性位置泉眼，更好地监测和评价岩溶水.土壤酸沉降污染严重或酸雨频繁地区易导致岩溶水pH值呈酸性.对泉水流量和水质的研究有利于科学开发利用岩溶水资源.
Abstract:Karst water, referring to the groundwater that is hosted in karst pores, serves as the major water source for production and life in southern China. With the increasing social demand for water, the development and utilization of karst water resources is becoming more and more important. By regularly monitoring the spring flow, conductivity and pH value of Yuelu Mountain, combined with the rock-soil layer property of Yuelu Mountain and rainfall of Changsha City, the statistical analysis and Spearman rank correlation coefficient method are used to study the spring flow changes and qualitatively evaluate the water quality. The results show that rainfall replenishes karst water and increases spring flow. The spring flow is not only related to rainfall but also affected by soil infiltration rate and rainfall duration. The Spearman rank correlation coefficient method can be used to quantitatively calculate the correlation between conductivity and time, and indirectly judge the influence of surrounding environment on spring water quality, which is conducive to identify the representative location of conductivity, better monitor and evaluate karst water. The pH value of karst water tends to be acidic in areas with serious acid precipitation pollution of soil or frequent acid rain. The study of spring flow and water quality is beneficial to scientific development and utilization of karst water.
