| 摘 要： | 通过对廊坊市地下水漏斗演化过程与逐年降水的相关分析，揭示了地下水位下降漏斗的气象干旱响应模式，即气象干旱促使人类过度开采地下水资源，从而进一步加剧水文干旱、地下水位下降漏斗及地面沉降灾害。在时间序列上，气象干旱呈波浪起伏状特征，而地下水位下降漏斗及地面沉降则表现为缓变性、积累性和不可逆性，气象干旱的阶段性终止并不能阻止地下水位下降漏斗及地面沉降的继续发展与蔓延。同时提出了合理开采地下水、大力开展水循环利用、发展节水农业等对策。

| Abstract: | The correlation between groundwater funnel and annual precipitation in Langfang,Hebei Province was analyzed in this article.Results show that overexploitation of groundwater triggered by meteorological drought further aggravated hydrological drought,the groundwater funnel and land subsidence disasters.In the time series,the meteorological drought presents the wavelike characteristic,while the groundwater funnel and the surface subsidence display the slow developing,cumulative and irreversibility characteristics,thus temporal termination of meteorological drought cannot prevent the groundwater funnel and the surface subsidence development and spread.At the same time,some countermeasures such as reasonable exploitation of groundwater,re-use of water resource, development of water-saving agriculture are proposed. |
