为揭示洞穴滴水元素的季节变化特征及其影响因素,从2011年12月至2013年5月对广东英德宝晶宫洞穴内的3个滴水点滴水中的Ba、Sr、Ca、Mg元素进行为期一年半的监测,结果发现:13个滴水点滴水中的元素浓度基本上都表现出明显的季节变化特征,但不同的元素之间和不同的滴水点之间的季节变化趋势存在差异,表明不同的滴水点其不同的元素浓度变化的影响机制各有不同.2强降水对洞穴滴水的元素浓度具有稀释作用,Drip1和Drip2各元素浓度在有强降雨的5、6月都呈现低值.33个滴水点的Mg/Ca和Sr/Ca比值都具有较强的正相关关系,且都表现出旱季高,雨季低的特点.表明宝晶宫3个滴水点的Mg/Ca、Sr/Ca很可能受到降水量、岩溶水来源、上覆土壤的淋滤作用以及碳酸盐先期沉积作用等因素共同影响,并能较好地反映该地区的干湿变化.
In order to reveal the seasonal variation characteristics of drip irrigation elements and their influencing factors, the Ba, Sr, Ca and Mg elements in three drip irrigation water samples from the cave of Yingde, Jingdeng, Guangdong Province, from December 2011 to May 2013, After a year and a half of monitoring, the results showed that the elemental concentrations of 13 drip drip water basically showed obvious seasonal variation, but the seasonal variation trend between different elements and different drip points showed different Of the drip point of the different elements of the concentration of the impact of different mechanisms vary .2 strong precipitation on the element concentration of cave drip dilution, Drip1 and Drip2 each element concentration in June and June have a low rainfall showed a low value .33 There was a strong positive correlation between the Mg / Ca and Sr / Ca ratio in each drip point, and all showed the characteristics of high dry season and low rainy season.The results showed that Mg / Ca and Sr / Ca in the three drip points May be affected by factors such as precipitation, source of karst water, overlying leaching of soil and pre-sedimentation of carbonate, and can better reflect the change of wet and dry conditions in this area.
