| 摘 要： | 以3期遥感图像为数据源,经图像处理,并结合野外考察,建立解译标志进行遥感解译。结果表明,开都河下游绿洲区的盐渍化土地面积呈先增加后减少趋势,盐渍化程度呈先加重后减轻趋势;盐渍化土壤主要分布在开都河沿岸低洼地和博斯腾湖湖滨地区及其北岸清水沟、曲惠渠、乌什塔拉渠两岸附近;盐渍化的形成与研究区地形地貌、地下水以及干旱的气候条件密切相关,人类农业活动对盐渍化土壤形成具有重要作用。

| Abstract: | Three temporal remote sensing images were used as the main sources of information.The images were processed in combination with field investigation.The results show that soil salinization of the land area had increased from 1973 to 1990,and then declined from 1990 to 2005;the extent of land salinization had increased from 1973 to 1990,and then decreased from 1990 to 2005.Land salinization is distributed around the low-lying areas of the Kaidu River,lakesides and Qingshui Drainage,Quhui Drainage and Wushital... |
