摘　　要：本文以辽宁清原县为研究区,以2018年资源档案数据和采伐作业设计为基础,结合少量地面调查和同时期资源三号卫星遥感影像,提取与森林蓄积量有关的自变量因子,利用多元线性回归方法构建森林蓄积估算模型,最后利用构建好的模型对无森林蓄积量小班进行估算。The paper takes Qingyuan County,Liaoning Province as the research area.Based on 2018 resource archive data and logging operation design,combined with a small amount of ground surveys and simultaneous resource satellite remote sensing images,independent variable factors related to forest volume were extracted and a forest volume estimation model was established using multiple linear regression method.Finally,the constructed model was used to estimate the forest stock volume of small plots without recorded forest stock data.

关 键 词：森林蓄积量 多元线性回归 模型估算 遥感影像
