摘要: 为研究红树林生物量的遥感估算方法,提取了广西和海南红树林TM遥感影像的光谱及纹理特征,结合地面调查所得126个样地生物量数据,进行多元逐步回归分析。结果表明,建立的生物量估算模型通过相关检验,可以高效、快速地进行红树林生物量的估测。

关键词: 生物量估算, 纹理特征, 稳健诊断, 多重共线性

Abstract: In order to research the biomass of mangrove based on remote sensing, the multiple regression analysis was used to estimate the biomass of mangrove, by extracting spectral information and textural features from TM images and combining the field survey biomass data of 126 samples. The result showed that all the biomass estimation models got through relevant test and could be efficiently and rapidly applied to the biomass estimation of mangrove.

Key words: biomass estimation, texture feature, steady diagnose, multicollinearity
