对贵州关岭县花江纳朵洞内4个滴水点（D4、D5、D7、D8）和1个池水点（DC），及洞顶上方的泉点（NDS）和降水（NDR）的水文水化学特征进行1个水文年的观测，其结果表明：（1）纳朵洞内4个滴水点Ca2＋在2012年12月至2013年11月这段时期内，变化的趋势基本一致，在6月开始迅速上升，9月达到高峰，然后缓慢下降，其特点是夏秋高冬春低。（2）4个滴水点 Sr／Ca 主要与降水有关，表现出雨季低，旱季高的特点。%One hydrological year monitoring on the hydrochemistry of 4 dripping waters (D4 ,D5 ,D7 ,D8)and one pool water (DC)of Naduo Cave in Huanjiang ,Guanling County ,Guizhou Province and one spring (NDS) on the top of the cave and the rainfall (NDR)has been carried out .It was found that (1)the Ca2+ of the 4 dripping waters had the same changing direction from December 2012 to November 2013 ,which increased rapidly in June till September and then decreased slowly .Temperature might affect the Ca2+ ,making it high in summer and autumn and low in winter and spring .(2)the Sr/Ca of the 4 dripping are lowest in the rainy season and highest in the dry season ,mainly associated with precipitation .
