【摘要】 <正> 陕西省碳酸盐岩主要分布于秦巴山地,其次分布于渭北“旱腰带”(北山一带),以及零星分布于府谷县城(图1)。岩溶区地下水赋存于震旦系至三叠系下统碳酸盐岩裂隙溶洞中,富水性极不均一。其赋存规律主要取决于气候、岩性、构造等的综合作用。陕南米仓山及羊山一带,属亚热带湿润气候,水热条件优越,岩溶发育,富水性极强。而渭北及陕南北部属暖温带半湿润气候,岩溶发育较差。更多还原

【Abstract】 The carstic water in Shaanxi Province exists in the fissure cavern of carbonate rocks and the watery feature does not very uniform in distribution They are controllod by the condition of lithologic character,climate and tectonics etc.Around Micangshan and Yanshan area in the sourthern part of Shaanxi,the sandstone is widespread and is marked by damp and hot and unique feature of carstic geophological landscape.Most of the underground rivers and large carstic springs occur in this,among them the discharge of the largest underground river reachs 10000 L/s in miner Nanhai.The total discharge of large carstic spr ing and underground rivers are 1453 Mm~3/a ia all Shaanxi Province,which is considered to be used as an available rich resource in rolling country.更多还原
