▌凌先有 藏在深沟无人识，一朝选入世界册。今年9月10日，吉隆坡传来喜讯，2025年世界灌溉工程遗产名录正式揭晓，我国共有四项灌溉工程遗产荣 登榜单，分别是北京门头沟永定河古渠灌溉工程、云南元阳哈尼梯田、江苏赤山湖灌溉工程以及四川湔江堰。作为京津冀地区首个获此殊荣 的水利灌溉系统，深藏于京西深沟的永定河古渠灌溉工程声名鹊起。 赶在北京今冬第一场雪降临的前一天，我与永定河文化研究会的朋友们相约，从永定河文化博物馆出发，奔赴这场与千年水脉的约会。 登上引水闸的平台，向永定河下游望去，右边是奔腾不息的永定河水，左侧是一条长长的渠道，如青色丝带般沿着山坡边沿向远处延伸。我 们沿着古渠旁的道路步行前行，午后的阳光毫无温度地倾洒下来，在冰冻的古渠上反射出白色的光芒。 王健一边走，一边为我们讲述这条灌渠的往事。他说，付家台灌渠在五大灌渠中，建成时间最晚、建设历时最长、历经磨难也最多。1903 年，村民傅有元、傅有遥为改变守着永定河却"靠天种田收获少，糠菜代替半年粮"的困境，决定集资修建引水渠道。他们尝试了多次，却因 缺乏水利知识而屡屡失败，最后不仅集资款耗尽，有些家庭甚至倾家荡产。村民杨永福看在眼里，急在心里，他从煤矿请来 ...
