河西走廊水利遗产调查记②|搜渠记
Xin Lang Cai Jing· 2025-06-09 04:44
一、开启搜渠模式 一般印象中,用地图描绘一片年均降水量不足50毫米的内陆干旱区域,代表荒漠的焦黄似应是其理所当然的主色调。2009年1月笔者在清华大学水 利系观看《甘肃省疏勒河流域灌区图》的经历颠覆了这样的刻板认识:两米多长、一米多宽的巨大图幅中,密如蛛网的渠系、星罗棋布的水库塘 坝以巨大的压迫感扑面而来,蓝色的线条与色块牢牢占据画面中心,这片河西走廊西端的广袤大地在此完全变成陌生的样子。图中贯穿左右的最 醒目连续线条不再是标记兰新铁路、连霍高速公路或312国道等交通线,疏勒河水系渠线构成的坐标体系定义了一种前所未见的空间关系。文献 中"华戎所交一都会"的敦煌在此具象为由党河灌区大小渠网编织成的绿洲,诗篇中被反复吟唱的阳关则是库姆塔格沙漠边缘一块被渠道与水塘簇 拥的高地。甚至图中的等级秩序也自成一体,依据区划中心级别而被赋予不同符号字号的大小城镇显然居于次要地位,位于总干渠与河流的交汇 处而被醒目标记的水利枢纽、以逐渐细微的字体依次标注出的各级分水闸门才是绝对主角,它们以陌生的名字与远离聚落的姿态与熟悉的河西走 廊保持着距离。 自此而后,历代"以渠为纲"的灌区地图引发了笔者的浓厚兴趣。凝视代表各种天然或人工水 ...

今年的高考人数,8年来首次下降了
3 6 Ke· 2025-06-09 00:55
6月,又是一年一度的高考季。 前几天,教育部公布了,2025年全国高考报名人数——1335万人。 相较于去年的1342万人,减少了7万人。 这是2017年以来,高考报名人数首次减少。 高考填志愿,未来哪几个专业增速最快呢? 下面我们一起聊一聊吧! 高考人数8年来首降主要有这四个原因 1、适龄人口自然减少 今年的高考生,对应的是出生于2006-2007年的人口,而这两年的出生人口分别为1581万和1591万,均低于之前(2000-2005年)1599万 - 1771万的出生规 模。 人口基数的减少,就直接导致了今年考生人数的下降。 相信很多朋友比较好奇,为什么一直上涨的高考人数,突然就下降了。 这中间到底发生了什么? 未来几年,高考人数还会下降吗? 2、统计口径发生调整变化 之前统计高考报名人数里,包含了中职单招和专升本等考生。 比如: 2021年河南省统计的高考人数中,中职与专升本的考生,就占比超过了 30%。 而今年,部分省份对统计高考人数的口径做了调整,这也导致2025年高考人数有所下降。 3、复读生规模有下降趋势 去年高考人数1342万人中,复读生就有小几百万人。 可见,复读生也是高考大军中的一大派。 ...

为什么国内航班上网特别难?
Hu Xiu· 2025-06-08 01:38
01 前两天,我坐国航,从北京飞上海。 刚系好安全带,空姐走过来提醒:"女士,我们这架航班配有机上Wi-Fi服务。" 我愣了一下。 不是因为她态度好,而是因为这在中国境内航线上堪比刮中了彩票。 起飞后,我激动地连上Wi-Fi,打开小红书,想起飞前刷几条段子助眠。 结果,转圈圈,黑屏,缓冲。几分钟过去,视频还没加载出来。 我一边傻等,一边看空乘已经推完一轮饮料服务。旁边大哥水都续了第二杯了,我第一条笔记还没打开。 我甚至怀疑,飞机都快飞到上海了,网还卡在首都机场T3航站楼。 但你别笑。能上网,已经是国内航班的稀有特权了。 根据民航系统数据,中国目前只有大约6%的飞机支持Wi-Fi服务。 能连上是幸运,能连上还能用,那就算开了挂。 这趟"慢网"飞行让我从期待到郁闷,直到下飞机刷新闻时,看见一条让我差点坐回登机口的消息: 到底谁更懂现代旅客的心?还真就挺难评的。 美联航已经启用了首批星链Starlink航班,用马斯克的星链技术,提供高速、低延迟、全程覆盖的空中互联网。 最离谱的是,美联航前程万里会员免费用。不加钱!不加钱!不加钱! 公开信息显示,美联航这次不玩虚的,直接把星链装进了自家300多架支线飞机,年底前装完 ...
