一个非比寻常的信号。 为了"强省会"战略，四川省开建了一个投资额高达575亿元的超级引水工程，叫做"引大济岷"，该工程的主要目的就是给成都平原引水。 575亿元是什么概念，比深中通道还高了100多亿，将其视为四川版的"深中通道"毫不为过。 分析认为，引水成功之后，成都继续做大做强，就没有后顾之忧了。 图片来自"智谷趋势" 四川为什么要新建这个引水工程？ 这里涉及到一个冷知识，那就是：成都缺水。 岷江是成都主要的水源地，但同时经常给成都带来水患。战国时期，秦国派蜀郡太守李冰父子修建都江堰，用"鱼嘴分流"的方式将喜怒无常的岷江分成两 条河，一条河走灌溉用水（内江），一条河用来泄洪（外江）。 后来的事情大家都知道了，都江堰建成之后，成都平原变身一个"水旱从人、不知饥馑"的风水宝地。 然而，经过两千多年的发展，成都平原的人口和经济规模，远超战国时期，仅都江堰一个水源地是不够的。 01. 四川要花575亿，为成都引水 11月7日，一个叫做"引大济岷"的工程建设动员大会在四川雅安天全县举行。该工程工期8年，投资额超过575亿元，是四川有史以来投资最大、线路最长 的引水工程，堪称新时代的"都江堰"。 "引大济岷"是什么意思 ...
