摘要
同一含水系统中在至少两个排泄区(点)之间有足够的地下水补给源情况下,两个排泄区(点)之间才能形成地下水分水岭。白于山中段和西段的洛河组含水层深埋于白垩系下部,在地层结构和地质构造控制下,基本上没有补给,在泾河最低排泄区控制下,洛河组地下水穿过白于山由北向南径流。因此,白于山中段和西段只是浅层地下水分水岭,对下层洛河组地下水流无控制作用,不是完全的地下水分水岭。
There will be a possible groundwater divide, if it can get enough groundwater to recharge between two discharging areas in a aquifer system. Luohe aquifer is below cretaceous aquifer system, and can＇t be recharged by stratum structure and geological conformation influence, which is located in the Midwest of Baiyu Mountain. Groundwater is flowing through Midwest of Baiyu Mountain from north to south, so Baiyu Mountain isn＇t an absolute groundwater divide, which just is a shallow groundwater divide in the Midwest of Baiyu Mountain.
