黃河寧夏灌區探秘

2019-09-16 07:54來(lái)源：新華網(wǎng)

寧夏引黃古灌區唐正閘。2017年10月寧夏引黃古灌區入選世界灌溉工程遺產(chǎn)，這也是黃河干流上的首個(gè)世界灌溉工程遺產(chǎn)（9月1日無(wú)人機拍攝）。新華社記者劉詩(shī)平攝

在銀川市賀蘭縣常信鄉潭渠村的一處水閘旁，村民用水協(xié)會(huì )會(huì )長(cháng)孫萬(wàn)銀輕點(diǎn)手機，灌溉支渠上的水閘開(kāi)始緩緩升起。今年以來(lái)，這條支渠上的100多座老式閘門(mén)全部經(jīng)過(guò)改造，換成了現代化的智能閘門(mén)。

“以前的閘門(mén)是手提式的，村民需要引水時(shí)便自行打開(kāi)，這就造成了管理問(wèn)題，不少人引完了水也不關(guān)閥門(mén)，水資源白白浪費?！睂O萬(wàn)銀說(shuō)，現在村民要引水，需先給用水協(xié)會(huì )打電話(huà)，管理人員在手機上遠程操作打開(kāi)閥門(mén)，引水完成后再由管理人員遠程關(guān)閉閘門(mén)，這項措施使這一片區用水節約了20％以上。
