摘要
根据2013-2014年对贵州关岭纳朵洞洞内4个滴水点(D4、D6、D7、D10)进行2两年的动态监测,分析物理化学特征的季节变化对地表气候的响应情况,得出以下结论:(1)洞穴滴水的水温,主要受当地气温的影响,运移路径不同与滴水点通风情况是导致各滴水点水温存在差异的原因;(2)洞穴滴水pH值显示都为碱性,冬季pH值高于夏季,由于2013年干旱而2014年夏季暴雨,导致2014年pH值整体高于2013年,反映了当地降雨的年际变化;(3)纳朵洞滴水的EC和Ca^(2+)在2013-2014年既有同样的变化趋势,又有所区别,EC是雨季高,旱季低,而Ca^(2+)浓度表现出冬春下降,夏秋升高的特点。
According to 4 drip water sites（D4,D6,D7,D10）for dynamic monitoring of 2 years in Naduo Cave of Guizhou in 2013-2014,the response analysis of seasonal variations of physical and chemical characteristics of surface climate,draw the following conclusions：（1）the temperature of drip water is mainly affected by the local temperature,the different migration path and dripping water sites wind is the cause of each drop point temperature difference;（2）cave drip water pH value will be showed alkaline,pH value is higher than the winter summer drought in 2013 and 2014,due to heavy rainfall in summer,in 2014,the value of pH is higher than in 2013,reflecting the interannual variation of local rainfall;（3）the EC and Ca^（2＋） of cave drip water in 2013-2014 has the same change trend,EC is high in the rainy season and low in dry season,while the Ca^（2＋） concentration showed a decline in winter and spring,increased in summer and autumn.
