摘要
以内蒙古陕坝地区为研究对象,选取Radarsat-2影像数据,野外采集土样,室内测定K+、Na+、Ca2+、Mg2+、Cl-、SO42-、HCO3-、CO32-含量,采用灰色关联分析法分析了HH极化和HV极化对微观离子的响应。结果表明,对离子的响应强度HH极化要高于HV极化,同种极化方式对不同期土壤离子的响应情况也不相同,12月份的响应要高于10月份。
Taking Shanba area in Inner Mongolia as the research object, the Radarsat-2 image data were selected, soil samples were collected in the field, 8 ion content was measured indoor to analyze the HH polarization and HV polarization response of micro-ion by the method of gray relational analysis. The results showed that the HH polarization response on the ion intensity is higher than the HV polarization. The same polarization response to the different stages of soil ion is not the same, higher in December than in October.
