摘要
20世纪70年代后期,徐州市进入城市高速发展时期,生产生活用水量逐年增大,地下水常年处于超采状态,地下水环境演化趋势偏离正常轨道,局部呈现恶化的态势,主要表现在地下水动力场演化、地下水化学场演化和地质灾害负环境效应三方面。徐州市地下水环境演化轨迹和城市高速发展的相关分析结果和拟合函数表明,城市高速发展对地下水环境的演化具有明显的线性驱动作用。本文详细分析了这种驱动作用并提出了城市与地下水环境和谐可持续发展的对策。
Since the end of 1970＇s,due to high-speed development of Xuzhou City,more and more groundwater was used and the groundwater had been over-pumped every year.Therefore,the groundwater evolution began to be out of order,including groundwater dynamic force evolution,groundwater chemistry evolution and geological hazards,and some parts had been getting aggraved.Based on correlation analysis and fitting function between the groundwater evolution and hight-speed development of Xuzhou City,it is obvious that there is very strong driving action to groundwater evolution due to city high-speed development.In this paper,this driving action is analyzed in details.Meanwhile,some controlling methods for keeping groundwater resource sustainably developiing are put forward.
