选用天津地区89个观测井1990-2010年的月地下水埋深，基于Mann-Kendall法研究地下水埋深的变化趋势、埋深变幅年代际变化特性及其年内分配变化特性，并探讨影响地下水埋深的相关因素。结果表明：观测期内天津平原区不同含水组地下水埋深的时空变化和影响因素差距较大，尤其在2000年后，由于受开采量的影响，地下水年际和年内变化更为剧烈。研究结果可为天津地区地下水资源的可持续利用和保护决策提供重要参考。

We selected monthly groundwater buried depth series of 89 observation wells from 1990 to 2010 in Tianjin, in order to study the change trend , inter-annual change , and intra-annual distribution change of the groundwater buried depth using the Mann-Kendall method , and to explore the factors that influence the groundwater buried depth.The results show that, during the observation period, the temporal and spatial variation and influencing factors of the groundwater buried depth differed largely in different aquifers in the plain area of Tianjin , especially after the year 2000 , when significant inter-annual and intra-annual changes of groundwater occurred due to mining.These research results can provide important references for sustainable utilization and protection of groundwater resources by the water resources administrations in Tianjin .
