| 摘 要： | 内蒙古东乌珠穆沁旗的额吉淖尔盐湖四周为丘陵所环绕,在构造上属于中生代燕山早期强烈升降运动所形成的额和宝力格菱形断陷盆地的一部分。古地貌属于吉林郭勒——额吉淖古河道中下游转弯处的牛轭湖。处于典型草原地带,优势植被克氏针茅草原正处于严重退化过程中,给盐湖资源造成不利的影响。 近年来盐湖退化迅速,水位下降,产盐面积缩小,质量变劣。退化的原因:一是气候趋于旱化,二是风沙侵袭山洪淤积,三是植被破坏、地表侵蚀加剧,四是不合理的开采的影响。防止退化是当务之急,必须逐步采用新工艺进行采盐生产,合理用水,划定缮湖地,植树种草,改善环境,加强管理,使盐湖资源实现永续利用。

STUDIES ON THE ENVIRONMENTAL CONDITIONS AND DEGRADATION SITUATION OF THE EJINOOR SALT LAKE IN DONGWU BANNER OF INNER MONGOLIA |
| |
| Abstract: | The Ejincor Salt Lake in Dongwu Banner of Inner Mongolia is encir-cled by low hills around, and it is belonging to Bone part of the Ehebaoligesinking basin formed by the strong tectonic movement in the early stage ofMesozoic Yanshan Movement.In palaeogeomorphology it is an elbow lake for-med at the turning point of the ancient Jilingele-Ejinoor river channel.Now the lake is situated in the typical grassland zone, with its dominantvegetation of Stipa kirylovii being deteriorated causing harmful effects to theSalt Lake resources. In recent years the Salt Lake is degrading rapidly, with the lowering ofwater level and the reduction of salt-producing areas and salt quality wor-sening.The paper points out that the degradation are mainly caused by thefollowing effects: the climate becoming arid, eolian sand intruding and floodsilting, destruction of vegetation and serious erosion of surface soil, and theunrational exploitaion actions etc. To prevent the above-mentioned deterior-ations, the author suggests some new measures to be taken to realize the goalof utilizing the salt lake resources forever. |
