　　昨天，一张“卫星拍摄最新中国夜景图”走红网络，北京、山东、江浙等地在夜里灯光集中，十分耀眼，而江苏、山东也成了网友们调侃的热点，戏称两省大亮全因“学生刚刚开始上晚自习”。但记者经过细心比对发现，这张图和去年8月美国国家海洋和大气管理局发布的一组卫星图像非常相似，而且这组图也是用来研究灯光使用情况的。

江苏亮瞎了 Jiangsu bright blind

　　昨天不少媒体官方微博转发这张“卫星拍摄最新中国夜景图”，还附带一句“江苏的学生刚刚开始上晚自习”，而图中江苏的确比其他地方都要“亮”得多。据网友描述，这个“夜景图”其实是卫星拍摄的“夜间灯光分布图”，虽然黑乎乎一片，但依然能从图上浅灰色的轮廓线轻松看出是中国的地图。里面包括了我国大部分省市，除了人烟稀少的西南地区外，剩余区域都被许多亮点占领，沿海一些城市的光点因为太过密集，连成了大块圆点状，而中部的小光点则连成了网。北京、山东、江苏、四川、广东等人口密集的省市都被大片的光点覆盖，而江浙沪交集处的灯光最为闪亮，其中江苏的“贡献”最大，密集的灯光甚至从苏南绵延到了苏中地区，都是一整片的光带，引来众多网友感叹：“江苏真是亮瞎了！”

Yesterday a lot of media official micro bo forwarding this picture"Satellite pictures latest China night scene graph",Also attached a"Jiangsu students just started at wanzi xi",In the figure and jiangsu indeed than any other place to"bright"than.According to the net friend describe,this"Night scene graph"Is actually the satellite pictures"Night lighting profile",Although the dark, a piece of,But can still from the chart grayish contour line is easily see a map of China.It includes the majority of provinces and cities in our country,In addition to the sparsely populated southwest external,Residual area are many window occupation,Coastal some of the city's spot because it was too dense,Connect the large circle point,Central and small spot, connect to the Internet.Beijing/shandong/jiangsu/sichuan/Guangdong provinces and cities populated by large spot coverage,And with the lights of the jiangsu in the most shining,The jiangsu"contribution"maximum,The lights of the dense even from southern jiangsu stretch to the middle area,Is a whole piece of light band,Draw many users exclamation:"Jiangsu is really bright blind!"

　　“全国教育看江苏”这句话在互联网上经久不衰，再加上各种升学考试中被奉为“神级”的山东学生，这张“夜景图”又被网友们赋予了新含义，众多转发这张图的网友都会跟着附带一句“江苏的学生刚上晚自习”或者“山东的学生还没有下晚自习”，来解释两省的灯特别亮的“真相”。

"The national education see jiangsu"This sentence in the Internet enduring,Add all kinds of entrance tests was made"God level"Shandong students,This piece of"Night scene graph"Was the netizens endowed with new meanings,Many forwarding this picture with a net friend will follow"Jiangsu students just at wanzi xi"or"Shandong students haven't arching over under",To explain the provinces of lamp special bright"truth".

　　虽然调侃江苏学生“挑灯夜读”的网友很多，但也有不少网友猜测，江苏如此之亮，也与其丰富的夜生活以及亮化工程有关。拿南京来说，“南京治安不错，肯定也和晚上路灯比较多有关”，网友“驻山”说。另外网友们也发现，“夜景图”中几处明显很亮的地方都是人口密集的大城市，“人多自然用的灯也多，想像一下每盏灯后面都会有一个玩电脑的，更亮了”。

Although poking fun at jiangsu students"Stay over night"Net friend of many,But there are not a few net friend guess,Jiangsu so bright,Also with rich nightlife and lighting engineering related.Take for nanjing,"Nanjing security good,Must have and evening lamps more relevant",Net friend"In mountain"said.In addition the netizens also found,"Night scene graph"Several significant in very bright place are large city with a dense population,"Many natural light also many,Imagine each lamp behind will have a play computer,More bright".
