摘　　要：地面沉降严重影响着城市的基础建设并制约着城市的经济发展,目前已普遍证实,过量开采地下水造成的地下水文地质力学平衡的破坏是导致地面沉降的最主要原因。采用肯达尔非参数秩次相关检验法对华北某市地下水水位及地面沉降的历史数据进行分析,并对两者的变化趋势进行了检验。结果表明,1990年—2004年该市沿海地区地下水中第Ⅰ～Ⅲ含水组的水位呈上升趋势,第Ⅳ、Ⅴ含水组的水位呈明显下降趋势,地面则无明显沉降趋势。统计结果与实际情况基本相符,说明该数据检验方法应用于对地下水水位变化及地面沉降趋势的分析是较为合理的。Land subsidence, a common urban geological disaster, senousty restricts city s construction and economical developments. It is now widely proved that the overexploitation which unbalances the underground hydrology geology is the main reason of the land subsidence. The Kendall test method was used for the analysis of historical monitoring data on water table and land subsidence of a city in the North China Area, and the change tendency of the both was examined. The results of data processing collected from 5 aquifers in the city from 1990 to 2004 show that the aquifers Ⅰ - Ⅲ have an ascending tendency while the aquifers Ⅳ and Ⅴhave a dropping tendency, and there is no significant land sub sidence. The statistical results basically conform to the actual situation, showing that the application of the Kendall test method in the analysis of water table change and land subsidence tendency is more reasonable.
