生态公益林是构筑国土生态安全的重要基础,是实现“两山”理念的重要保障。以湖南省不同植被类型(针叶林、阔叶林、针阔混交林、竹林和灌木)公益林为对象,利用2021年湖南省公益林固定样地监测数据、Landsat 8遥感数据,构...展开更多 生态公益林是构筑国土生态安全的重要基础,是实现“两山”理念的重要保障。以湖南省不同植被类型(针叶林、阔叶林、针阔混交林、竹林和灌木)公益林为对象,利用2021年湖南省公益林固定样地监测数据、Landsat 8遥感数据,构建不同植被类型公益林生物量支持向量机模型、决策树模型和随机森林模型3种反演模型。结果表明,3种模型中,随机森林模型估算精度最高,其中竹林的拟...
