摘要
地面沉降是在自然和人为因素作用下,由于地壳表层土体压缩而导致区域性地面标高降低的一种环境地质灾害现象,是一种难以补偿的永久性环境和资源损失。福州市温泉区存在大面积沉降现象,给经济发展、城市建设和人民生活带来极大威胁。本文对温泉区地面沉降影响因素、地面沉降现状及表现形式以及与地下热水的相关关系进行了分析,指出地下热水开采与地面沉降在时间、空间分布上存在极好的相关性,过量开采是导致地面沉降的直接诱因,最后提出防治措施。
Caused by the natural and man-made factors, the ground subsidence is the disaster phenomenon of environmental geology with regionally ground level decreasing, which resulted in the compact of soil. It is hardly compensable and permanent loss of environment and resource. There is the ground subsidence in hot spring area, Fuzhou. It menaces the development of economy, building of city and life of persons. The factor, present situation, manifestation and relation to geothermal water were analyzed in the thesis, which points to ground subsidence and exploitation of geothermal water is better correlative, and which excessive exploitation is directly induced cause to ground subsidence. Its measures of control is put forward.
