杨树人工林生长与收获系统模型构建
Construction of growth and yield models for poplar plantations
摘要
Abstract
Based on the data collected from fixed sample plots and investigated from typical sample plots over the years, growth and yield models of poplar plantations in southern area of China were established. The established model system included stand average diameter and basal area model, stand diameter distribution model, diameter-height curve model and stem taper model. Using site quality, stand age and stand density as model�s control variables, stand volume and stand merchantable volume model were developed according to different management intensity. Moreover, the system software with independent intellectual property rights was also developed for poplar plantations in southern area of China. The sample test showed that the stand volume and merchantable volume estimated by the growth and yield models estab-lished in this paper were reliable, and the average relative error was <10%.关键词
