Abstract

Abstract:

From 2019 to 2020,China participated in the 2020 Global Forest Resources Assessment Remote Sensing Survey (FRA2020 RSS) organized by the United Nations Food and Agriculture Organization(FAO),and completed the tasks within China. This article described the development process of the global forest resources assessment,introduced the system framework and technical methods of FRA2020 RSS,and analyzed the reflection and enlightenment of FRA2020 RSS on the construction of an integrated forest resources monitoring system in China.

Key words: forest resource assessment, remote sensing survey, unmanned aerial vehicle, monitoring system
