  报告人简介(Brief Introduction): 

  唐昊,美国马里兰大学助理教授,主要研究方向是基于Lidar的陆地生态系统三维遥感观测,是NASA新一代全球对地生态系统观测激光雷达Global Ecosystem Dynamics Investigation (GEDI)的科研团队核心成员。在美国国家科学院院刊(PNAS)、环境遥感(RSE)等权威学术刊物以第一作者或通讯作者发表论文十余篇。

  报告摘要(Lecture Abstract): 

  Forests exhibit dynamic responses to changes of natural environmental conditions and influences of anthropogenic activities. 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.
