| 摘 要： | 以山西省忻州市忻府区为例,研究了ETM+影像TN值与土壤有机质含量的相关性,确定与土壤有机质含量有相关性的波段,运用回归分析方法建立基于ETM+影像的光谱定量反演模型。结果表明,忻府区土壤有机质含量自北向南逐渐增加,自西向东逐渐减少,且中部地区小于四周。

| Abstract: | Taking Xinfu District in Xinzhou City,Shanxi Province as an example,through analyzing correlation between ETM+ image TN value and soil organic matter(SOM),the related wavelength were obtained.The regression analysis method was adopted to establish spectral quantitatively regression model based on ETM+ image.The results showed that SOM in Xinfu District are increasing gradually from the north to the south while reducing gradually from the west to the east,and the central region is less than the surroundings. |
