2012年2月20日,我国首部地面沉降防治规划获得国务院批复,此举意味着在全国范围内防治地面沉降已被提上日程。《2011年—2020年全国地面沉降防治规划》指出,目前全国遭受地面沉降灾害的城市超过50个,全国累计地面沉降量超过200毫米的地区达到7.9万平方公里,并有进一步扩大趋势。据了解,目前地面沉降主要有三大重点片区,分别为长江三角洲地区、华北平原、汾渭盆地。由于地面沉降,有城市甚至被预言会在几十年后消失。
On February 20, 2012, China’s first land subsidence prevention and control plan was approved by the State Council, a move that means to prevent land subsidence across the country has been put on the agenda. The National Land Subsidence Prevention and Control Plan for 2011-2020 points out that at present there are over 50 cities in China suffering from land subsidence and the cumulative land subsidence over 200 mm in China reaches 79,000 km 2 and further expands. It is understood that there are currently three major subsidence land subsidence areas, namely the Yangtze River Delta region, the North China Plain, Fenwei basin. Because of land subsidence, some cities are even predicted to disappear after decades.
