灰色关联度分析在水文地质中的应用——以山东省济宁长沟水源地为例

山东济宁长沟水源地裂隙喀斯特含水系统受孔隙水和地表水影响,运用灰色关联度,对裂隙喀斯特水和孔隙水、裂隙喀斯特水和地表水之间分别进行水位和水化学组分关联性比较分析,确认孔隙水与喀斯特水的关系比地表水与喀斯特水的关系密切。沿运河一带运河水补给孔隙水,运河以南孔隙水与裂隙喀斯特水互为补排关系,而运河水与裂隙喀斯特水无直接水力联系。

Application of Grey Association Ratio Analysis in Hydrogeology-Set Changgou Water Source as an Example in Jining City

Fissure-karst water-bearing system of Changgou water s ource in Jining city is influenced by pore water and surface water. By Using gre y association ratio,water dynamic state and chemical components between fissrue-karst water and pore water, and between fissure-karst water and surface water a re contrasted and analyzed seperately. It is confirmed that pore water and Canal water has a more close ralation than that between canal water and karst water. Along the Canal, pore water and fissure-karst water have a recharge-discharge re lation, while in south of the Canal, canal water and fissure-karst water have no direct water power relation.
