摘要

通过对重庆芙蓉洞上覆表层岩溶泉水、土壤渗透水和洞穴滴水水化学特征的系统监测

发现3种水(泉水、土壤渗透水和滴水)元素的变化幅度在年内都有各自的变化范围

Ca2+、Mg2+、Sr2+和SO24-在土壤渗透水中年平均浓度分别为25.55

11.04

0.026

15.39mg/L

在表层岩溶泉水中分别为65.76

33.16

0.035

21.18mg/L

而在洞穴滴水中分别为64.37

37.87

0.044

11.38mg/L。3种水之间存在大致协调同步的季节变化规律:Ca2+、Mg2+、Sr2+浓度的变化呈枯水期变幅大、雨季变幅小的特征

SO24-浓度则因不同的点而存在一定差异。受土壤水热条件以及生物过程的季节性变化影响

土壤渗透水中各元素变化表现出一定的季节性。6个洞穴滴水中Ca2+、Mg2+和Sr2+浓度在冬季枯水期出现低值

MP2点的SO42-浓度随降雨的增加而逐渐增大。因此

不同滴水点运移的路径、时间和环境条件不同

导致对降水的季节响应也存在一定差异。

Abstract

Through system monitoring to the hydrochemical characteristics about springs

infiltration waters and drips

it was found that there are different variation ranges among the three types of water in a year.The average concentration of Ca2+

Mg2+

Sr2+ and SO2-4 were 25.55

11.04

0.026

15.39 mg/L in the soil infiltration of water;and 65.76

33.16

0.035

21.18 mg/L in spring water;while 64.37
