基于遥感影像的广西壮族自治区林业资源动态监测与评估

Dynamic monitoring and evaluation of forestry resources in Guangxi based on remote sensing images

文章基于遥感影像数据,构建了广西壮族自治区林业资源动态监测与评估的理论分析框架,包括林地覆盖类型提取、林地蓄积量估算、林地变化检测和林业资源状况评价4个步骤。阐释了遥感影像与地面因子建立模型的定量表达机制,遥感数据与地理信息系统及全球定位系统融合使用的信息融合机制,并从时空序列与实践演绎角度探寻林业高质量发展的可能。

This paper constructs a theoretical analysis framework for dynamic monitoring and evaluation of forestry resources in Guangxi based on remote sensing image data,including four steps:extraction of forest cover type,estimation of forest volume,detection of forest change,and evaluation of forestry resource status.This article explains the quantitative expression mechanism for establishing models between remote sensing images and ground factors,as well as the information fusion mechanism for integrating remote sensing data with geographic information systems and global positioning systems.It also explores the possibility of high-quality forestry development from the perspective of spatiotemporal series and practical deduction.
