摘要:
通过对Aster遥感影像前9个波段的相关系数、标准差和诊断指数的分析，发现Aster遥感影像1，2，3波段的土壤反射率对土壤含盐量最为敏感。利用Aster遥感影像1，2，3波段作为自变量，盐碱土含盐量作为因变量进行逐步回归分析，建立土壤反射率数据与土壤含盐量数据之间的统计模型，利用决策树分类将地物分成5类，反演得到研究区盐碱土含盐量的空间分布图。研究发现，基于统计模型的遥感反演效果较好，具有一定的参考和应用价值。
Abstract:
Through analyzing the correlation coefficient, standard deviation and diagnosis index of the former nine bands in Aster remote sensing image, it finds that the soil reflectivity of b1, b2, b3 in Aster remote sensing image is more sensitive to salt content in the soil. Stepwise regression analysis is made by using the b1, b2, b3 in Aster remote sensing image as independent variable and salinity in soil as dependent variable, and the statistical model of the soil reflectivity data and the soil salt content data is established. The surface object is divided into five kinds by using decision tree sort, in order to obtain the spatial distribution map of salinity in saline-alkali soil. The research indicates that the effect of remote sensing reversion based on statistical model is better and the research result has a certain value of reference and application.
