摘要: 温州市永强平原经济发达,工业化的发展和地下水无计划的开采,使永强平原地面沉降较为严重,永中累计沉降量超过300mm。为了更好地对永强平原地面沉降做出分析预测,本文通过研究区域地质环境、地下水开采量、地下水位的动态变化特征及2005~2010年的地面沉降监测资料,分析地面沉降速率、范围、沉降量,从而进一步探讨地面沉降与地层结构、地下水动态的关系,同时采用年开采量和年平均沉降速率预测2015年的地面沉降量。分析结果对深化永强平原地面沉降研究具有一定意义。Abstract: Wenzhou Yongqiang plain has prosperous economy, the development of industrialization and the planless exploitation of groundwater, bringing the subsidence badly, the accumulative total in Yongzhong area exceeds 300mm. For the analysis and forecast in Yongqiang plain, this paper researches the geology environment, groundwater exploitation, groundwater level dynamic characters, and land subsidence monitor data of 2005 - 2010, to discuss the relationship between the stratum structure and groundwater level, and adopts the annual exploitation and the annual average subsidence speed to forecast accumulative total to 2015. The analysis results will be importance for deeply study in Yongqiang plain.
