| Abstract: | The paper studies the vegetation biomass of the Yellow River wetland in Zhengzhou by using RS and GIS technology based on the CCD spectrum remote sensing image of CBERS 2B satellite acquired on May 7,2009.The field measurement data of the vegetation biomass helps build the inversion model by multi-linear regression method and obtain the optimal calculation model by comparing and analysis.The results show that the inversion model calculation accuracy reaches 86.32%,and it is proved that use of the CCD spectrum remote sensing image of CBERS 2 B satellite can meet the need of the vegetation biomass inversion. |
