研究：北京每年下沉多达11厘米

研究发现，整个城市都在下沉，而朝阳区下沉最严重。上世纪90年代以来，朝阳区繁荣发展，高楼大厦和环路不断涌现。研究人员说，一些地区下沉不均匀的特性会对建筑物和其他基础设置造成威胁。

Tens of thousands of water wells are thought to exist in and around Beijing, many of them used in farming and landscaping. The state has regulatory power over installation of wells but is inconsistent in applying it, according to one leading Chinese environmentalist.

据称北京及周边地区有数万口水井，其中很多用于农田灌溉和绿化。国家对打井有监管权，但据一位领头的环保人士说，实际执行情况并不理想。

“There are some rules but the enforcement is doubtful,” said Ma Jun, director of the Institute of Public and Environmental Affairs in Beijing. Ma said he wasn’t surprised subsidence was relatively high in the Chaoyang district given its rapid growth of recent decades. He expected it to keep moving east as the city sprawled in that direction.

公众环境研究中心主任马俊说：“有一些监管规则，但执行成效令人怀疑。”马俊说他对朝阳区地表下沉速度更快并不惊讶。因为朝阳区近几十年来发展非常快。他预计随着整个城市向东扩展，地表下沉将会继续向东延伸。

China inaugurated a mega-engineering project aimed at mitigating Beijing’s water crisis. The state completed construction of the South-North Water Diversion.
