Abstract: The authors of this paper choose the base of poplar forest and paper integration of Zhongye Meili Paper Industry Group in Zhongwei City as the research object, use the CBERS/CCD image and synchronous plot data, as well as method of correlation analysis to screen out two variables NDVI and RVI. The correlation coefficient between stem volume and NDVI and RVI is 0.948 and 0.981. Then three regression simulation equations are modeled for gauge stem volume based on NDVI, RVI, NDVI and RVI,respectively. The R2 of simulation equations is 0.899, 0.963 and 0.987, respectively. All the simulation equations pass the correlation examination. The forest timber volume of the target plot is 641804.70m3, 655889.57m3 and 672143.34m3 respectively.

Key words: CBERS/CCD, timber volume, regression model, intensively-managed plantation
