歷史上的慶陽湖

中生代(dai)侏羅紀，甘肅大(da)部分(fen)河流向東流淌，在隴東形成大(da)湖和(he)沉積。當時最大(da)的湖盆(pen)，地(di)質學家稱為慶陽(yang)湖。

注入湖(hu)區最(zui)大河流是(shi)從安西、敦煌發源的古阿(a)拉善河，其次是(shi)古黃河、蒙(meng)古河、古納水(shui)河，湖(hu)區范圍涉及陜(shan)、甘(gan)、寧、蒙(meng)，浩瀚(han)遼闊。

侏羅(luo)紀后(hou)期，發生了(le)被稱為燕山運動(dong)的(de)造山運動(dong)，甘肅陸(lu)地再次抬升(sheng)，陜(shan)甘寧盆(pen)地湖(hu)泊曾一(yi)度干涸(he)，在湖(hu)區西部出現南北(bei)走向的(de)賀蘭山和六盤山。

大約在第四(si)紀晚期，今(jin)慶陽市(shi)東部(bu)的子午嶺從湖(hu)盆中(zhong)上升(sheng)為南(nan)北(bei)走向(xiang)的長梁。殘積湖(hu)水(shui)沖破(po)南(nan)部(bu)峽谷(gu)，向(xiang)南(nan)流入涇水(shui)，形成馬蓮河、蒲河水(shui)系。

1978年5月，環江翼(yi)龍在慶城縣卅鋪的發現，證明了慶陽湖的存(cun)在，演示出慶陽地(di)區古地(di)理氣候狀況。因為它只能滑翔不能遠(yuan)飛，主要靠捕食小(xiao)魚為生(sheng)。
