中文摘要	新疆位于我国西部内陆干旱区,生态环境脆弱,土壤退化及盐碱化现象严重。研究综合运用3S技术与相关辅助数据相结合的方法,通过目视解译遥感影像,开展新疆绿洲耕地盐渍化现状调查。结果显示,2005年,新疆绿洲盐渍化耕地为162.02*10~4hm~2,总体上轻度盐渍化比例最大,中度次之,而重度较少,分别占耕地总面积的24.33%、6.28%和1.46%。可见,耕地盐渍化问题依然严峻,威胁着新疆绿洲的生态安全和社会经济发展。针对目前耕地盐渍化现状,最后提出了治理耕地盐渍化的若干对策。
英文摘要	Xinjiang is located in inland arid area in the west of China.Its ecological environment is so fragile that soil tends to degradation and salinization.This research applied remote Sensing(RS),Geographic Information System(GIS) and Global Positioning System(GPS)to investigate salinization of cultivated land by interpreting the remote sensing image with combination of the field survey and other data.Some results are concluded as follows: in 2005,there were 162.02*10~4 hm~2 salinization cultivated land,the light-degree of salinization cultivated land took largest proportion,followed by moderate-degree salinization cultivated land,the heavy-degree salinization of cultivated land occupy Minimum proportion which occupied 24.33 %,6.28%,1.46% of total area of cultivated land,respectively.The salinization of cultivated land has constituted a serious hazard to oases ecosystem environment and economic development of Xinjiang.Thus,more concern should be given to it.So,in the end of paper,some countermeasures were suggested to deal with this problem.
