天然林单木生长模型研究综述

摘要

Forest stand age, species composition, site quality, competition are considered as difficulties of developing individual-tree growth model in natural forests. Solutiuons for the difficulties are summarized, but there are no widely accepted theory, and much work on these issues are still needed. Types and research status of individual-tree growth model in natural forests are elaborated. Moreover, the developing trends of individual-tree growth model in natural forests are also put forward from aspects of mechanization model study, forecasting precision improving of models, three-dimensional models, visualization research etc.%建立天然林单木生长模型的难点有林分年龄、树种组成、立地质量和林木竞争效应的表达等问题,介绍针对这些问题的解决办法,但目前仍没有广泛认可的理论体系,仍需进行大量的研究工作.阐述了天然林单木生长模型的种类及研究现状,从机理化模型的研究、模型预估精度的提高、三维模型及可视化研究等方面总结了其发展趋势.
