摘要
50年代至80年代初,新疆平原沙漠区湖泊普遍处于退缩状态,一些湖泊干涸或基本干涸,这是湖泊所在流域上、中游地区灌溉事业发展的必然结果。到目前为止,湖泊干缩所引起生态环境的变化,其范围主要限于湖周有限区域;变化的幅度尚未达到对人类生活和生湖泊及湖周有限区域生态环境的恶化中,人类不正确的活动方式占了很大比重。
Lakes in the plain and desert area in Xinjiang autonomous region have been shrinking greatly due to irrigation since the 1950s, and some lakes have even dried up, resulting in such environmental effects as land desertization, fauna-flora degradation, fish-yield reduction and the local climate changes. Since these effects were overestimated and the main causes to arise effects mentioned above were confused, further discussion is made on these effects comprehensively.
