摘　　要：GreenLab模型是目前研究最为深入的植物功能--结构模型,但传统的测树学方法难以满足GreenLab模型构建所需要的外观形态参数和生物量参数。因此,该文提出了一套能够满足GreenLab模型构建需求的测树方法。首先分析了GreenLab模型的参数需求,然后以欧美杨107为测量实例,详细探讨了树木的参数测量步骤以及测量过程中的关键问题,形成了一套科学而系统的参数测量方案。结果表明:该测量方案可以快捷有效地实现参数的测量,其测量结果可以满足GreenLab模型构建的需求。GreenLab model is a functional-structural plant growth model that is studied the most in recent years.Traditional forest measurement cannot achieve detailed structural parameters and biomass parameters which are essential for constructing GreenLab model.To solve the problem,this paper put forward a tree measurement that can meet the demand of GreenLab model.The authors first analyzed the parameter requirement of GreenLab model,discussed the measuring steps and some key problems in measuring process by using Populus euramericana 'Neva' as measuring sample,and brought forward a scientific and systematic measurement.Results show that the measurement can get parameters effectively and the measured parameters satisfy the requirement of GreenLab model.
