林层分层是热带林生态学最古老的概念之一,但对林层分层的定义和测定方法的不同造成了林层分层是否存在及如何划分的争议。作为森林调查的因子,对林层划分方法的研究具有测树学和群落学双重意义。文中从定性、定量和遥感3个方面综述林层划分的主要方法,介绍剖面图的绘制、应用及特点,描述TSTRAT和LMS划分方法的详细步骤,并通过与FVS和MIDCL等划分方法的对比分析了这4种方法的特点。
Stratum stratification is one of the oldest concepts in tropical forest ecology. However, the definition and determination of stratification of stratum cause disputes over whether stratification exists or not. As a factor of forest investigation, the research on the stratification of forest strata has dual meaning of tree-seeking and community. This paper summarizes the main methods of forest stratification from three aspects of qualitative, quantitative and remote sensing, introduces the drawing, application and characteristics of cross-sections, describes the detailed steps of TSTRAT and LMS classification methods, and compares with FVS and MIDCL The characteristics of these four methods.
