中文摘要	玛纳斯河灌区是新疆重要的农业绿洲之一,其发展受土壤盐渍化制约,土壤盐渍化信息获取成为首要问题。以Landsat-OLI卫星影像和野外调查数据为基础,对修改型土壤调整植被指数(MSAVI)和盐分指数(SI)之间的关系进行了综合分析,并提出了MSAVI-SI特征空间概念,进而构建了盐渍化遥感信息提取指数模型(MSI) 。结果表明: ①不同程度盐渍化类型MSI平均值差异特征明显,其差值在0.35 ~ 0.43,因此,MSI指数可以作为盐渍化信息快速提取的指标。② 灌区土壤受盐渍化侵扰严重,尤其从下游农业生产区到古尔班通古特沙漠过渡的生态脆弱区,受地下水影响明显的中段,土壤盐渍化仍是土地退化的重要原因。本研究对土壤盐渍化遥感监测和管理,以及区域环境保护具有重要意义。
英文摘要	The Manasi River Basin is one of the main agricultural oases in Xinjiang, its development is restricted by soil salinization. How to survey soil salinization becomes as a primary problem in the study area. In this paper, the relationship between the Modified Soil-adjusted Vegetation Index (MSAVI) and salinization index (SI) was analyzed based on the Landsat-OLI image and field survey data. MSI model was established based on the concept of MSAVI-SI feature space. The results are as follows: ① There was an obvious difference of MSI values (0.35-0.43) of saline soil with different salinization degrees,which indicated that the MSI model was suitable for surveying soil salinization in the study area; ② Soil salinization was very serious in the irrigated area of the Manas River Basin,especially in the areas with fragile ecology in the lower reaches. Because the groundwater level in the middle reaches was high, soil salinization was still one of the important factors resulting in soil degradation in the irrigated area. This research could provide a reference for the information management of soil salinization and ecological environment protection.
