| 摘 要： | 利用西藏自治区2006年森林资源连续清查的天然云杉林实测样地资料,通过构建非线性联合估计模型系统,研究建立了天然云杉林总消耗率、枯损率、采伐率三者一致兼容的估测模型,为西藏天然云杉林的消耗量估测提供了参考依据,也为类似模型的研建提供了经验借鉴.

| Abstract: | By using the ground samp le p lots of 2006 Continuous Forest Inventory in Tibet, two compatible modelsystems for deleted volume rates ( total removals rate, mortality rate, and cut rate) of natural Sp ruce forest ( Picealik iangensis var. hirtella, Picea likiangensis var. balfou riana)were established based on the app roach of non2lineardependent estimation. The model systems can be used for p redicting the stand volume consump tion of natural Sp ruceforest in Tibet, and the method for building compatible model system can be referenced to establish similarmodels. |

| Keywords: | mortality rate cut rate compatible model non-linear dependently estimated model system modeling |
