摘　　要：根据项目区2006年的森林资源二类调查资料,以及2005年、2013年、2014年的3期TM遥感影像,典型选取29个小班开展了外业验证调查,对比分析了典型验证调查结果和二类调查结果。根据U检验结果,29个小班验证调查的蓄积平均值和二类调查蓄积平均值基本是一致的,没有显著性差异,说明俄方提供的森林资源二类调查数据的总体蓄积是可信的;根据F检验结果,单个验证调查小班公顷蓄积与二类调查公顷蓄积差值波动较大,可信度较低。According to data of forest resources inventory for planning of Russia, 29 forest resource sub - compartments were selected to carry out the field verification survey, The data of forest resources inventory for planning and the data of validation are compared and analyzed. According to U test results, There was no significant difference between mean volume of the survey and the mean volume of the validation sur-vey , indicating that the data of forest resources inventory for planning is credible. According to F test re-sults , the difference of single mean volume is large between survey and validation, and the reliability is low.
