| 摘 要： | 本文选择生态环境脆弱的艾比湖地区为研究对象,以2007年Landsat TM 影像资料为基础,采用SVM分类方法,进行土地利用类型分类和土壤盐渍化分类.在ArcGIS下计算不同土地利用类型的土壤盐渍化敏感性指数,通过盐渍化敏感性指数与各土地利用类型面积的比重建立了区域土壤盐渍化敏感度模型,利用克里格插值法得出区域土壤盐...

| Abstract: | This paper chose the Ebinur lake region as the study area,and used the Landsat TM remote sensing data in 2007 and support vector machine(SVM) to classify land use types and saline soils.Then,we used the ArcGIS to calculate sensitivity index of soil salinization and built the sensitivity model of regional soil saliniza-tion by using sensitivity index of soil salinization and proportion of different land use types.We also used the Or-dinary Kriging to get a spatial distribution map of sensitivity degree of re... |
