贵州省大小井地下河系统之间关系分析

On the Relation between the Two Underground Rivers in the Daxiaojing Region,Guizhou

贵州省大小井地下河系统是贵州境内最大的两条地下河,流域面积1 943.2Km2,出口位于贵州黔南地区罗甸县懂当乡大小井村。两条地下河紧靠在一起,它们之间地下水系统边界以及是否存在水力联系都尚不清楚,为了弄清两条地下河之间的关系,通过连通法对大小井地下河进行了示踪试验进行分析。研究表明,在航龙至马鞍寨区间,两条地下河系有着密切的水力联系;在鞍寨谷之后则互不关联,相互独立。

Underground river system with a basin area of 1 943.2 km2 in the Daxiaojing region is composed of two underground rivers which are the greatest ones in Guizhou. A test on hydraulic connectivity indicates that the two underground rivers are in close relationship between Chuanlong and Maanzhai and bear no relation down the Anzhai Valley.
