摘要:从林分直径结构模拟预测模型的选择以及模型参数的求解方法2个方面,对林分直径结构模拟与预测模型的国内外研究现状进行了较为详细的论述,总结指出林分直径结构模型的研究正围绕参数法和非参数法2种方法展开,重点归纳总结了理论方程法、最相似回归法等几种主要模拟预测方法以及百分位法、回归法等常用的模型参数求解和预测方法,分别指出了各种模型及参数求解方法的优劣,并对当前研究工作存在的问题及今后研究的重点进行了讨论。本项研究着眼于实际应用的层面,旨在为今后的研究提供阶梯,以有助于该项研究工作的展开。
This paper,from two aspects,discussed the internal and external study situation about the model of modeling and prediction of stand diameter structure,summarily indicated that the study of stand diameter structure model was unfolded around two methods of parametric approach and nonparametric approach,mainly introduced a few main modeling and prediction methods like theoretical equation method,k-nearest neighbor estimation method,and a few common evaluation and prediction methods like percentile method and regression method,indicated respectively the advantages and shortages of models and calculation methods of parameters,and discussed present problems and following emphases in studies. This paper,in the view of practical application,aimed to provide a study platform for following studies.
