Water environment problems received extensive attention in recent years, take Jinan karst spring region for example, groundwater evolution characteristics were analyzed by observing changes of spring level, spring runoff, water quality and safety yield, authors thought the main reason of drying-up was inadequate understanding of the safety yield index. According to the characteristics of Jinan spring...
Eco-water (layer) refers to the water body closely related to the ground vegetation layer. It is conserved in leaves, roots, vegetation humus layers and root soil layers, which is capable of precipitation interception and rivers and/or groundwater supplementation. As a challenging issue in the hydrological cycle field, the eco-water and its resource quantity are difficult to be quantified by ordinary...
