歷史上的慶陽湖
中生代侏(zhu)羅紀,甘(gan)肅大(da)部分河流向東(dong)流淌,在隴東(dong)形(xing)成大(da)湖和沉積。當時(shi)最(zui)大(da)的湖盆,地(di)質學家(jia)稱為(wei)慶(qing)陽湖。
注入(ru)湖區(qu)最(zui)大河流是從安西、敦(dun)煌(huang)發源的古(gu)(gu)阿拉善河,其(qi)次(ci)是古(gu)(gu)黃(huang)河、蒙古(gu)(gu)河、古(gu)(gu)納水河,湖區(qu)范圍涉及(ji)陜(shan)、甘、寧、蒙,浩(hao)瀚(han)遼闊。
侏羅紀(ji)后期,發生(sheng)了(le)被稱為燕山運動(dong)的造山運動(dong),甘(gan)肅陸地再次抬升,陜甘(gan)寧盆地湖(hu)泊曾(ceng)一度干涸(he),在湖(hu)區西(xi)部出現南北走(zou)向(xiang)的賀蘭山和六盤山。
大約在第四紀晚期(qi),今慶陽市東部(bu)的(de)子午(wu)嶺從湖盆中上升(sheng)為南北(bei)走向(xiang)(xiang)的(de)長梁。殘積湖水(shui)沖破南部(bu)峽谷,向(xiang)(xiang)南流入(ru)涇水(shui),形成(cheng)馬蓮河、蒲河水(shui)系。
1978年5月,環江翼龍(long)在(zai)慶(qing)城縣(xian)卅鋪的發現,證明了慶(qing)陽(yang)湖的存在(zai),演示(shi)出(chu)慶(qing)陽(yang)地區古(gu)地理氣候狀況。因為它只(zhi)能滑(hua)翔不能遠(yuan)飛,主要靠(kao)捕食小魚為生。
