#摄影# 你所不知的坎儿井地下水利工程,是与中国横亘东西的万里长城、纵贯南北的大运河齐名的中国古代三大工程之一,是伟大的地下水利灌溉工程。坎儿井是一种特殊的水源,古称“井渠”,至今已有2000多年的历史。如今吐鲁番坎儿井已得到了很好的保护,人们基本看不到过去那种家家相通的水源了。

#热词#“十三五”期间我国生态环境质量总体改善 8项指标已提前完成——生态环境部副部长赵英民在发布会上表示,“十三五”时期是迄今为止生态环境质量改善成效最大的五年,我国将如期完成“十三五”规划纲要确定的9项污染防治指标。China will be able to meet all of its nine pollution control targets during the 13th Five-Year Plan (2016-20) period as scheduled. "The environmental improvements in the country after 2015 have been bigger than those in each of the other five-year plan periods," said Zhao Yingmin, vice-minister of ecology and environment, at the news conference.
9项指标分别是:
全国地表水质量达到或好于Ⅲ类水体比例(the proportion of surface water with a water quality rating of Grade III or higher)
地表水质量劣Ⅴ类水体比例(the proportion of water with quality below Grade V)
细颗粒物(PM2.5)未达标地级及以上城市浓度(density of PM 2.5 in prefecture-level cities with low air quality standards)
全国337个地级及以上城市空气质量优良天数比率(the proportion of days with good air quality in 337 prefecture-level cities)
化学需氧量、氨氮、二氧化硫、氮氧化物排放总量(discharge of chemical oxygen demand, ammonia nitrogen, sulfur dioxide, and oxynitride)
单位GDP二氧化碳排放(carbon dioxide emissions per unit of GDP)
