冷湖:从石油小镇到观星胜地
Xin Lang Cai Jing· 2026-01-01 18:45
(来源:光明日报) 转自:光明日报 在青海省海西蒙古族藏族自治州茫崖市冷湖镇的戈壁滩上,有一座"英雄地中四井"纪念碑,碑前矗 立的老式抽油机已静止多年。 1958年,这里原油喷涌,拉开了冷湖油田作为我国当时四大油田之一的序幕。在此后的20年里,数 万石油大军会聚于此,车辆来往不息,热闹非凡。 然而,随着资源逐渐枯竭,这座因石油而兴的城镇迅速衰落。冷湖面临着许多资源型城镇共同的困 境:资源枯竭后,出路何在? "就像一座空城。"2015年,时任海西州住房和城乡建设局副局长的田才让调任冷湖时,这里常住人 口最少时不到300人,大量楼房空置,街道空旷。 当时的田才让只有一个念头:"不能眼看着冷湖消失在我们手里。"他和同事们仔细梳理了当地所有 的资源与条件后,将希望寄托于发展旅游业。 于是,一场冷湖的转型探索,由此开始…… 拯救冷湖于消失边缘 随着冷湖台址获得国际认可,各大科研机构和高校的望远镜项目纷至沓来。如今已有12家单位14个 项目45台望远镜在冷湖天文观测基地落地建设,投资额达30亿元。其中,在已建成的33台望远镜中,墨 子巡天望远镜、太阳磁场精确测量中红外观测系统等5台投入科学观测,多应用巡天望远镜阵等27台 ...
