关岭纳朵洞滴水的电导和pH值对气候的响应

Response of EC and pH Value of the Dripping Water to Weather in Naduo Cave in Guanling

通过2014年对纳朵洞滴水的电导、pH值1年的观测,分析洞穴滴水的电导和pH值对大气温度和降水的响应,得出结论如下：纳朵洞滴水pH值冬季高于夏季,PH值变化的范围在7.8~8.7之间,平均值为8.31,其值偏碱性,而降水pH均值为7.08,接近中性;b）纳朵洞滴水的电导夏季偏高,冬季偏低,与夏季高温多雨相关。

This paper analyzed the response of EC and pH value of the dripping water to atmospheric temperature and precipitation in Naduo cave in Guanling County , by one hydrological year monitoring in 2014. The conclusion is as follows： the pH value is higher in winter than the summer , its change.d range between 7.8 to 8.7, with a mean of 8.31, is an alkaline; and the average pH value of precipitation is 7.08, close to neutral; B）the EC of cave dropping water is high in summer, low in winter in Naduo cave,associated with high temperature and rainy in summer.
