云台山世界地质公园的水资源特征

为了更好地保护河南省云台山世界地质公园的水资源,从大气降水、地表水、岩溶地下水等方面,分析了云台山世界地质公园的水资源特征。结果表明:云台山世界地质公园降水丰沛,水质由北向南、由东向西逐渐变好;其地表水补给来源主要为大气降水和岩溶泉排泄,地表水化学类型主要为HCO3-Ca.Mg型、HCO3.SO4-Ca.Mg型和HCO3-Na型;而园区内的岩溶地下水是一种低矿化度、低硬度的淡水,其化学成分以Ca2+和HCO3-含量为主,其他离子次之,水化学类型以HCO3-Ca(Ca.Mg)型和HCO3.SO4-Ca.Mg型为主。

Water resource characteristics and protection in Yuntai Mountain World Geopark

In order to protect the water resources in the Ytmtai Mountain World Geopark of Henan Province, the property of the water resources was studied from the aspects of precipitation characteristics, surface water characteristics and hydro-chemical characteristics of karstie groundwater. The resuhs revealed that, in the Yuntai Mountain World Geopark, the rainfall is plentiful, the water quality becomes better as one moves from north to south and from east to west, the supply sources for surface water are mainly rainfall and spring drainage, the chemical types of the surface water are mainly the HCO3-Ca· Mg type, HCO3- SO4-Ca· Mg type and HCO3-Na type, karstic groundwater is the fresh water with the lowest mineral degree and lowest hardness, the main chemical components are Ca^2＋ and HCO3^-, and the main chemical types are the HCO3-Ca（Ca·Mg） type and HCO3·SO4-Ca·Mg type.
