Effects Analysis of Human Activities on Surface Water Resources Evolving Regime of Shandong Province

摘要

Surface water resources evolving regime refers to the temporal and spatial variation of surface water resources caused by changes of the underlying surface conditions due to human activities. This article analyzes the effects of human activities on surface water resources evolving regime in five concerned aspects, including the effect of multi-storage system, the effects of over-utilization of surface water and decline of groundwater table caused by over-extraction, the effects of water-soil conservation and urbanization, etc. It also analyzes the quantitative variation of surface water resources produced by the same amount of precipitation between present and natural underlying surface conditions by four sub-basins, and gives a preliminary prediction on its evolving regime in the future.
