Direct and accurate measurements of vegetation structure and its dynamics across large geographical extent yet are largely missing, preventing a more comprehensive evaluation of their roles in ecosystem services such as environmental protection and biodiversity conservation. Spaceborne light detection and ranging (lidar) technology can potentially fill this observational gap and advance our understanding of tropical forest ecology, such as the success of NASA's Ice, Cloud, and land Elevation Satellite (ICESat) mission deployed between 2003 and 2009. To continue the global observation of vegetation structure, two following spaceborne lidar missions, ICESat-2 and Global Ecosystem Dynamics Investigation (GEDI), are scheduled for launch in 2018. Similarities of these lidar missions form the basis for complementary observations that can explore vegetation structure dynamics at time scales ranging from seasonal to decadal. As a demonstration, we unveil the seasonal dynamics of vertical vegetation structure and suggest possible interactions between canopy layer and understory across the Amazon forests using lidar data from the ICESat. 欢迎各位老师和同学参加! 高寒生态学与生物多样性重点实验室 |
