摘　　要： 历史时期关中东部泾洛下游沮洳和盐碱地面积较大,人们采取挖渠排水,降低地下水位;引洪淤灌,放淤压碱。同时,采取种植水稻,让土壤脱盐,使关中东部盐碱地面积大为缩小。现今关中东部盐土的形成,与历史时期黄渭洛及支流河道变迁有关,与历史时期引洛洗盐时有间断有关,也与泾水下游引泾灌溉、种稻洗盐,放淤压盐等没有间断有关。 Even though there exited a vast of swamp and saline-alkali soil in the lower reaches of Jingluo River in eastern Guanzhong in the history,etc.,people made saline-alkali soil dwindle by resorting to the way of rice cultivation and desalinization,in addition to drainage ditches,flood diversion for irrigation,lowering water table,reducing alkali by release of mud etc.Nowadays the formation of saline-alkali soil here is closely related with three factors： the changes of river courses of Yellow rive,Weihe river and Luohe river;the intermittent activity of washing salt in the drawn water from Luohe river;the adoption of the various ways mentioned above in the beginning sentence.
