| Abstract: | The reflectivity of four kinds of soil samples in Qinghai alpline area was measured by ASD Hand Hold Spectroradiometer.The statistical analysis was made with organic matter content and ferric oxide content.The results show that the reflectivity of flowing aeolian sandy soil is greater than that of semifixed aeolian sandy soil,light chestnut soil and dark chestnut soil,and the content of organic matter is strongly correlative with absorption features of soil spectrum around 375 nm,575 nm and 775 nm;Ferric ox... |
