中文摘要	以开都河下游绿洲为研究区,选取1958年土壤类型图、1973年MSS、1990年TM和2010年ETM+遥感影像为数据源,采用光谱角分类法提取盐渍地信息,利用盐渍化动态度模型SSDI和土地转移矩阵进行盐渍化动态分析。研究结果表明:①1958年~2010年研究区盐渍地呈减少趋势,其面积减小866. 81km~2;盐渍化动态度SSDI为1.09;其中,中度盐渍化土地面积减小速度最快,盐渍化动态度SSDI为2.18。②3种不同类型盐渍化土地之间相互转化,中重度盐渍化土地转化程度最高,占其转移量的43.47%;3类盐渍化土地向非盐渍化土地和裸地转移,轻度盐渍化土地转移程度最高,占其转移量的80.59%。③研究区的年均温度、年蒸发量、年降水量、人口总数和农业生产总值与盐渍化土地面积均呈负相关,其中年均温度与盐渍化土地的相关系数值最大,其值为0.98;年蒸发量与盐渍化土地的相关系数值最小,其值为-0.28。
英文摘要	Taking the Oasis of the lower reaches of Kaidu River as an example,using the map of soil-type of Xinjiang uygur autonomous region in 1958,MSS image in 1973,TM image in 1990 and ETM+image in 2010 as data sources,the classification information of soil salinization was extracted with the spectral angle method,and the spatial and temporal changes in saltaffected soil in the study area were analyzed with the land utilization transfer matrix and salinization dynamic model SSDI. The results showed that: 1) the area of the salt-affected soil decreased 866. 81km~2 from 1958 to 2010,and SSDI was 1. 09,where,the area of the moderate salinized decreased most quickly,and SSDI was 2. 18. 2) the salt-affected soil types converted each other, the conversion degree of severe salinization was the highest, accounted for 43. 47 % ; the types of salt-affected soil converted to non-salt-affected soil and bare land,the conversion degree of slightly salinized soil was the highest, accounted for 80. 59%. 3) method of correlation analysis was applied using annual average temperature, annual evaporation, annual rainfall,population and total agricultural output as independent variables, and the area of salt-affected soil as the dependent variable. The individual variable and salinization land were negatively correlated,the correlation index between the annual average temperature and the area of salt-affected soil was the largest of all,and the value was 0. 98. The correlation index about the annual evaporation was the least, and the value was 0. 28.
