依据1981—2009年山东省经济与环境、地下水资源数据,采用城镇化率作为城镇化发展指标,污水排放量及地下水资源为环境指标,建立回归分析数学模型,分析山东省城镇化发展与污水排放及地下水资源之间的关系.结果表明:随着城镇化的快速发展,城镇化率与污水排放量成“U”形关系,与地下水资源量成“N”型关系,拟合成三次曲线方程的相关性较好.研究认为,随着山东省城镇化的不断快速发展,污水排放量呈上升趋势,而地下水资源量总体呈衰减趋势.

According to economic, environmental, and underground water resources data from 1981 to 2009 in Shandong Province, an optimal model was built by equation-fitting and regression to analyze the relationships between urbanization development , sewage discharge, and underground water resources , with the urbanization rate regarded as the development indicator and sewage discharge and underground water resources regarded as the environmental indicators.The results show that, with rapid urbanization, the urbanization rate exhibited a U-type relationship with sewage discharge , and an N-type relationship with groundwater resources , which fitted a cubic curve equation well.It is pointed out that, with the increasingly rapid development of urbanization of Shandong Province, the sewage discharge shows a rising trend and the underground water resources show a decreasing trend .
