为揭示洞穴滴水与地理环境的耦合状况，通过对金华双龙溶洞群中双龙洞、桃源洞、二仙洞的10个滴水点进行5个月连续观测，得到滴水点水样的Ca2+、Mg2+、Mg2+/Ca 2+、pH、电导率等数据，结果表明：降水量是影响滴水滴率的重要因素，但是滴水对降水的响应存在滞后效应；Ca2+与Mg2+含量不仅与外界气温降水条件有关，且受石灰岩纯度影响；Mg/Ca比值同时受降水、温度与岩溶水滞留时间的影响，洞穴沉积物中的Mg/Ca值可以直接反应滴水中Mg/Ca值的变化，从而指示洞穴外界降水条件的改变。此外，洞穴滴水水文水化学特性存在空间差异。

To reveal the coupling between drip water and geographical environment, analyzing the temporal and spatial variation of Ca2+ 、Mg2+ 、Mg2+/Ca2+、pH and conductivity of drip water sample in Double Dragon Cave , Taoyuan Cave and Two Fairy Cave for three consecutive months, the results showed that: the rate of drip water was closely related to the precipitation while there existed lag effect;the concentrations of Ca2+, Mg2+was not only effected by temperature and precipitation, but also related to the purity of limestone; Mg/Ca was influenced by temperature, precipitation and the detained time of cave water, Mg/Ca in sediment was a mirror to Mg/Ca in drip water. Therefore, it had a certain response to climate and environment change. In addition, there existed spatial difference.
