摘要

为探明人类农业生产活动对岩溶区地下河水质的影响

于2008年5月期间在重庆市青木关地下河上游入口、下游出口以及地下河上游入口附近水田共采集102个水样进行分析。根据监测期间上、下游岩溶地下河与监测水田的阴阳离子变化以及地下河中钠离子、硫酸根离子和硝酸根离子对氯离子的离子摩尔比率关系研究结果

监测期间青木关地下河水质变化与地下河上游的人类农业生产活动密切相关

地下河水中的硫酸根、硝酸根和氯离子对地下河上游的农业施肥活动表现出良好的响应关系。该时期的水质变化研究对以青木关地下河下游泉水为主要生活、生产用水来源的居民用水安全有一定的指导作用。

Abstract

In order to investigate the effects of farming and anthropogenic activities on underground river during fertilization period in karst area

we collected 102 water samples in the upriver

downriver

and paddy fields of Qingmuguan underground river in Chongqing in May

2008.According to the ions change in the upriver

downriver

and paddy fields of the underground river in the monitoring period and the molar ratios of Na+

SO2-4

NO-3 to Cl-

the water quality in the upper and lower reaches of the underground river is closely related to agricultural and industrial activities and SO2-4

NO-3 and Cl-in the underground river respond well to the fertilization activity.The springs in the downriver are the main water resource of living and production for local residents

study of the water quality in the period may have a certain role and significance in the guidance of water security.
