| 摘 要： | 选择了宁夏中卫市中冶.美利纸业集团的林纸一体化人工速生杨基地作为研究对象,以CBERS/CCD影像和同步实测样地数据为基础,利用相关分析方法筛选出相关系数分别为0.948和0.981的NDVI和RVI两个变量,分别构建了基于NDVI、RVI及NDVI和R VI的组合3个人工速生林地蓄积量回归估测模型,相关系数R2分别为0.899、0.963和0.987,通过了相关检验。估算出项目区的蓄积量分别为641 804.70m3、655 889.57m3和672 143.34m3。 |

| 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. |
