关于贵州地下水类型和含水岩组划分及其与地下水资源量计算关系的思考

正确划分地下水含水岩组和地下水类型,对较为准确的计算地下水资源量具有重要意义。但在目前实际工作中,地下水含水岩组和地下水类型的划分存在一定误区,导致地下水资源量计算成果较为粗放,以至于还可能给地下水的开发利用带来障碍。笔者认为,间互状不纯碳酸盐岩类归属于基岩裂隙水含水岩组较恰当,其所含地下水类型归属于基岩裂隙水更合适。在计算间互状不纯碳酸盐岩类地下水资源量时,宜扣除泥岩、粉砂岩和页岩的分布面积。

Consideration of Groundwater Type and Water Bearing Formation Division and Its Relation with Groundwater Resource Estimate

Correct division of water bearing formation and type of groundwater is very important for estimate the groundwater resource. But there are some misunderstanding in actual work, it causes the estimate result of groundwater resource is imprecise and makes barrier for exploration and development of groundwater. It＇s thought that the interstratified impure carbonate rock should belong to bedrock fracture groundwater bearing formation, its groundwater should belong to bedrock fracture groundwater. It＇s better to deduct the distribution area of mudstone, siltstone and shale when estimate the interstratified impure carbonate rock groundwater re- source.
