The ozone layer that shields life from cancer-causing solar rays is recovering at a rate of 1-3% per decade, reversing years of dangerous depletion caused by the release of harmful chemicals, a UN study said on Monday.

联合国本周一公布的一项研究称,为生物阻挡可致癌的太阳辐射的臭氧层正以每101%-3%的速度恢复,扭转多年来因排放有害化学物导致的臭氧层危险损耗的局面。

The four-yearly review of the Montreal Protocol found long-term decreases in the atmospheric abundance of controlled ozone-depleting substances and the ongoing recovery of stratospheric ozone.

每四年进行一次的《蒙特利尔议定书》评议发现,大气中受控臭氧损耗物质的总量呈长期下降趋势,平流层臭氧持续恢复。

The Antarctic ozone hole was expected to gradually close, returning to 1980 levels in the 2060s, the report said.

评议报告指出,南极臭氧破洞有望逐步闭合,到本世纪60年代恢复至1980年的程度。


"The Antarctic ozone hole is recovering, while continuing to occur every year. As a result of the Montreal Protocol much more severe ozone depletion in the polar regions has been avoided," the report said.

该报告称:南极臭氧洞正在恢复,而且每年的恢复都在进行中。正是由于《蒙特利尔议定书》,极地地区更严重的臭氧消耗已被避免。

"Evidence presented by the authors shows that the ozone layer in parts of the stratosphere has recovered at a rate of 1-3% per decade since 2000," UN Environment and the World Meteorological Organization said in a statement.

联合国环境规划署和世界气象组织发表一则声明称:报告编辑提出的证据显示,自2000年以来,部分平流层中的臭氧层以每101%-3%的速度恢复。

"At projected rates, Northern Hemisphere and mid-latitude ozone is scheduled to heal completely by the 2030s followed by the Southern Hemisphere in the 2050s and polar regions by 2060."

“按预估的速度计算,北半球和中纬度地区的臭氧预计将在本世纪30年代完全修复,随后是南半球在50年代修复,极地地区在2060年前修复。
