| Since the advantages of easily by mining and filling, well adjust ability, good water-quality and dynamic stability, groundwater becomes the important source of industrial and agricultural production, urban construction and drinking water. Shandong large-scale development of groundwater began in the late 1970s, along with the development of economy and the improvement of people's living standard, the demand for water resources are increasing. Long-term over-exploited groundwater rusults in a series of environmental problems such as regional groundwater continued to decline, ground subsidence, sea salt-water intrusion, soil salinization, desertification, and so on.According to the lithology, groundwater occurrence condition, water hydraulic characteristics and properties, groundwater aquifer is divided into four water rock groups that water rock group of loose pore water pressure, water rock group of deep pore water pressrue, water rock group of the karst water and water rock group of the bedrock fissure. Among them, the practical supply significance of groundwater are the shallow pore water, the deep pore water and the karst water. Hydrogeological condition evolution includes the changes of groundwater dynamic field and groundwater physicochemical field, the study of Shandong hydrogeological conditions'evolution should be done under the influence of human engineering activities. In the early of 1970s, groundwater flow was in a natural state because of the smaller mining, so we select the data of 1978 as the background value, divide the groundwater system into shallow pore water cycle system, deep pore water cycle system and karst water cycle system and analyze the evolution regularity of groundwater dynamic field and physicochemical field. In order to ensure the sustainable development and utilization of groundwater resources in Shandong, we proposed the countermeasures in the units of LuXiBei plains, LuZhongNan hills and Shandong peninsula. |
