橡胶林信息提取技术研究综述

摘要

橡胶林种植面积扩张与天然林保护之间的矛盾日益突出,利用遥感技术快速监测橡胶林分布及其动态变化,已成为热带天然林保护和土地利用规划决策的重要技术手段.通过查阅文献,对橡胶林遥感提取技术和龄组识别方法的研究现状进行了分析评价.橡胶林信息提取技术主要有监督分类、SAM-SID混合分类技术、面向对象决策树分类、模糊数学分类和基于训练样本的最近距离法等.介绍了橡胶林的龄组判别方法,包括依据时间节点和基于NDVI阈值的橡胶林龄组判别以及基于Landsat时间序列橡胶林林龄重构模型等方法,为林龄判断研究提供思路.%The contradiction between planting area expansion of rubber forest and natural forest protection is increaseing,the remote sensing technology used for monitoring the rapid distribution and dynamic change of rubber foresting has become a important technical means to protect tropical natural forests and decision-making of land use planning.Through the literature,this paper analyzed the study status of rubber forest extraction technology and age group identification method.The methods of rubber forest information extraction technology included supervised classification,SAM-SID mixed classification technology,object-oriented decision tree classification,fuzzy classification and recent distance method based on the training sample.This study also introduced age group discriminated method of rubber forest,including the time node and age group distinguish based on NDVI,rubber forest age reconstruction model based on Lanasat time series.This study provided a train of thought for the research of forest age judgment.
