In this paper, the author treated the forest growing system as a linear system and took the nursery stock growing system as an example. And a least square identification method was presented for a "multi-input-multi-output" linear static system in forestry. The method was further extended to the linear dynamic system and was used to solve the problems in the parameter identification of Picea asperata growing system. It could also be used for the "multi-goal" estimation in dynamic monitoring of forest resources...

In this paper, the author treated the forest growing system as a linear system and took the nursery stock growing system as an example. And a least square identification method was presented for a "multi-input-multi-output" linear static system in forestry. The method was further extended to the linear dynamic system and was used to solve the problems in the parameter identification of Picea asperata growing system. It could also be used for the "multi-goal" estimation in dynamic monitoring of forest resources with remote sensing technique.

本文视林木生长系统为线性系统,以苗木生长系统为例,阐述在林业工作中“多输入—多输出”线性静态系统参数的最小二乘辨识;进而推广到线性动态系统,解决云杉生长系统的参数辨识问题,并可借助遥感技术直接用于森林资源动态监测中的“多目标”估计。

Based on the analysis of influencing forest growth by site factors and by means of Path Analysis method,an influenced model of forest growth is proposed in this paper and is applied in evaluating artificial forest site quality in Changbai Mountain forest region.

本文基于对立地因子影响林木生长的系统分析,采用途径分析等方法建立了林木生长影响模型,并将其应用于我国长白山林区红松人工林林地质量的评价。
