摘要:森林生物量是指一个森林群落在一定时间内积累的有机质总量,是森林生态系统重要的特征数据,因此世界各国越来越重视对森林生物量的监测与研究,建立的生物量模型众多。大尺度森林生物量监测,是以省、流域、国家乃至全球为对象,在估算方法一致的前提下,对多个时间点的森林生物量进行估测和评价。开展全国森林生物量监测与评估,建立适合大区域的森林生物量的估算方法是一项重要的基础工作。
Based on national forest inventory data of Guangdong province, and selecting 176 sample plots dominated by Pinus massoniana, the biomass of the sample plots was estimated with different methods, which taking the keep sample stock volume as the independent variable and the sample plot biomass as the dependent variable. By comparing the calculation principle and process characteristics of these methods, the appropriate process was chosen to estimate the sample biomass. The results showed that the effect of continuous function for biomass expansion factor was poor, while that of the other methods was similar. For estimating the biomass of Pinus massoniana, the method of simultaneous equations with intercept was the best.
