上海市陆域承压含水层水位动态演化影响因素探究

摘要:
地下水水位动态演化具有明显的地方性特征.分析了2005~2013年各影响因素对上海市外环线内侧陆域各承压含水层最高水位和水位最大变幅的影响,发现全年降水量、地表水年径流总量、长江干流年过境水资源总量、第Ⅲ承压层地下水实际人工回灌量等对其都没有显著影响;太湖流域年过境水资源总量与其存在显著的中度正相关关系;地下水实际人工回灌量对其影响非常显著,属于强相关关系.

Abstract:
The dynamic evolution of groundwater level shows remarkable local characteristics.We analyze the data of factors that may influence of the highest groundwater level and the maximum amplitude of groundwater level in each confined aquifer in the land area within the Outer Ring Road of Shanghai City during 2005~2013.We find that the total volume of yearly rainfall,yearly surface runoff,yearly passing-by water in the mainstream of the Yangtze River,and the actual groundwater artificial recharge in the third confined aquifer,have no significant impact.There is a positive correlation between the highest groundwater level of each confined aquifer and the total volume of the passing-by water in the Taihu Lake basin.The volume of actual recharge of groundwater has a strong correlation with the highest groundwater level and the maximum amplitude of groundwater level in the confined aquifers.
Key words:  land area within the outer ring road of Shanghai city  highest groundwater level of confined aquifer  maximum amplitude of confined aquifer groundwater level  influential factors
