滇中地区针叶林碳储量遥感反演及动态变化分析
Remote Sensing Inversion and Dynamic Change Analysis of Carbon Storage in Coniferous Forests in Central Yunnan
摘要
Abstract
This article is based on data from four national forest resource inventories in Yunnan Province from 2002 to 2017,focusing on coniferous forests in four cities in central Yunnan(Chuxiong,Kunming,Qujing,Yuxi).Using the Gee platform to process Landsat satellite images and extract features,by comparing multiple linear regression,random forest,K-nearest neighbor,and gradient boosting regression tree(GBRT)models,GBRT was determined as the optimal estimation model to analyze the dynamic changes in coniferous forest carbon storage in central Yunnan from 2002 to 2017.According to the model calculation results,the coniferous forest area in Chuxiong and Yuxi continues to decrease,Kunming first decreases and then increases,while Qujing shows fluctuating changes.However,overall,the carbon storage and carbon density of coniferous forests in the four cities showed an upward trend from 2002 to 2017.关键词
