| 摘 要： | 四川红层盆地浅层风化带裂隙水是区内分布最为广泛和目前开采最多的浅层地下水类型,本文通过对大量控制性水样分析结果进行聚类分析,探讨了该地区浅层风化带裂隙水的水化学成分特征及其分布规律,结果表明区内91%以上的浅层风化带裂隙水为HCO3-型淡水,主要分布在中部方山丘陵小区、南部台状低山丘陵小区和东部侵蚀构造平行岭谷低山丘陵小区。该研究可为开发利用浅层地下水提供地学依据。

| Abstract: | Shallow crevice groundwater in Sichuan redbed basin is the most widespread groundwater in this area,and it severs as the main water resource at present.Based on the cluster analysis of massive groundwater samples,this paper summarizes the hydrochemical characteristics of its ingredient and its distribution rule so as to provide geoscience foundation for its development.The research discovers that in the redbed area,over 91% shallow weathering zone crevice water is fresh water and mainly distributes in the hilly and low-hill areas of the middle,southern and eastern parts. |
