长三角地面沉降损失3150亿元据《长三角地区地下水资源与地质灾害调查评价》显示,长三角地区三分之一的范围内累计沉降已超200毫水,面积近1万平方公里,造成地面损失近3150亿元。据上海市地质调查研究院称,长三角地区地面沉降最主要的原因是过量开采地下水。仅就上海而言,地面沉降的原因有30%来自高层建筑和重大工程项目本身的影响,其余70%则要归结为城市地下水的过分开采。
315 billion yuan of land subsidence in the Yangtze River Delta According to the “Investigation and Evaluation of Groundwater Resources and Geological Hazards in the Yangtze River Delta Region”, the cumulative settlement in the Yangtze River Delta region has exceeded 200 milliliters in water area and has an area of nearly 10,000 square kilometers, Nearly 315 billion yuan loss. According to the Shanghai Institute of Geological Survey, the main reason for the land subsidence in the Yangtze River Delta is the excessive exploitation of groundwater. In Shanghai alone, 30% of the ground subsidence is due to high-rise buildings and major construction projects themselves, with the remaining 70% attributable to over-exploitation of urban groundwater.
