摘要
内蒙古吉兰泰盐湖是荒漠区内很有经济价值的盐矿产地。本文针对近年来盐湖面临流沙覆埋危害的严峻现实,在分析盐湖区自然条件变化、沙侵危害规模、程度和原因的基础上,指出吉兰泰盐湖沙害导致盐湖自干盐中期阶段直接进入沙下盐湖阶段的过程,干旱化气候日益加剧是其自然控制因素,人类在盐湖区无节制地采樵和过度放牧,造成生态环境破坏是其触发因素,并提出了以保护生态环境为核心的综合治理对策。
Jilantai salt-lake is a base of salt mine which has great economic value in desert area,inner Monglai. Having countered the grim reality of the salt-lake that is confronted with the running sands'harmful intrud- ing in recent years;and based on analysis changs of natural conditions;scope,extent and reason of sands' intruding into the lake,this paper points out the process that the sand disaster results in the salt-lake direatly transformed from middle dry salt-lake phase into undersand salt-lake stage.Dry climate by degrees intensif- ing is the process' natural control factor,and it is its trigger factor that were overcutting woods and excen- tire hearding of animals around the lake area by human are to destroy the ecological environment.It also puts forward countermeasures in a comprehensive way which kernal is protecting the ecological environment.
