易罗池岩溶水系统水化学及径流过程

应用水化学常、微量元素、同位素分析,结合区域水均衡分析等综合手段,对云南省保山市隆阳区易罗池岩溶水系统的形成机理、径流特征进行了研究。水化学分析结果显示,易罗池泉水和沙河地表水相关性较好;水均衡分析显示,易罗池岩溶水系统中每年通过岩箐组（O_1y）灰岩接受大气降水的最大补给量约为100×10^4 m^3,占易罗池岩溶大泉出口总水量1 387×10^4 m^3/a中的很小比重。本文得出易罗池泉水为沿大宝盖向斜灰岩夹层发育的岩溶管道裂隙水,与上层非可溶岩基岩裂隙水无水力联系;岩溶泉水主要在大宝盖向斜O_1y地层灰岩夹层发育,于易罗池排泄,主要补给源为大宝盖向斜北西翼沙河上游朝阳寨一带的地表水。...

The Yiluochi karst water system lies in Longyang district, Baoshan City, Yunnan Province. It is on the western margin of the Baoshan basin. The primary aquifer of this system is composed of the sediment of Oly, which is bounded by the clastic rock and the fault. Geological structures with northwest and north- south trends dominate this region. The karst water system has a large karst spring with a flow rate of 440 L/ s, as the main source of drinking water in Longyang district of Baoshan City. The proposed Baoshan tunnel of the Darui railway will cross the Yiluochi karst water area. This work has studied the formation of the karst water system and the characteristics of the groundwater flow, in order to provide a scientific basis for the
