万华岩地区碳酸盐岩中普遍发育的非碳酸盐岩夹层 ,以及“土层 +裂隙层”表层岩溶带双层结构对岩溶动力系统和水循环具有显著影响 :非碳酸盐岩地段的地下水因其矿化度较低 ,CO2 含量较高 ,而具有较强的侵蚀、溶蚀能力 ,导致岩溶动力系统的物质和能量传输非常活跃 ,一个岩溶泉年溶蚀量 (以 Ca CO3计 )达2 795 .4 kg;由于非碳酸盐岩夹层的普遍存在 ,不仅阻碍地下水向深循环 ,而且还有利于土壤、植被的发育。土壤、植被与地表岩溶裂隙网络对区内岩溶地下水还具有较好的调蓄作用 ,以致使区内有众多的小泉点在地表出露。
The widely-developed non-carbonate intercalations in carbonate rocks in Wanhua rock area and the double-layer structure of epikarst zone in “soil + fracture layer” have significant effects on karst dynamic system and water cycle: in non-carbonate rock Due to its low salinity and high CO2 content, groundwater has strong erosion and erosion abilities, resulting in the active transport of matter and energy in the karst dynamic system. A karst spring annual dissolution (calculated as CaCO 3) reaches 2 795. 4 kg. Due to the prevalence of non-carbonate intercalations, it not only hindered the deep circulation of groundwater, but also benefited soil and vegetation development. Soil, vegetation and surface karst fissure network also has good regulation and storage of karst groundwater in the area, resulting in a large number of Koizumi points in the area being exposed on the earth’s surface.
