Dr. Jin Wu was invited to give a lecture on May 14th, 2018

Tropical forest photosynthetic metabolism helps sustain the ecosystem productivity and biodiversity, and largely regulates large-scale carbon and water cycling, generating various important climate feedbacks at regional and global scales. However, considerable uncertainties remain regarding how best to represent tropical forest photosynthesis in current Earth system models (ESMs), especially its sensitivity to climatic vs. biotic variation. Here, Dr. Wu introduced an integrative approach to predicting tropical […]

Researchers from Institute of Botany make significant progress on investigating the relative vulnerability of giant sequoia groves to a warming climate and multi-year dry periods

Researchers from Institute of Botany make significant progress on investigating the relative vulnerability of giant sequoia groves to a warming climate and multi-year dry periods

Giant sequoia (Sequoiadendron giganteum) trees, the sole living species in the genus Sequoiadendron, are among the largest trees and the oldest living things on Earth. However, with the global climate change, the current natural distribution of giant sequoia trees is restricted to an area of about 150 km2 on the western slopes of California’s Sierra Nevada, USA. During the past three decades, the Sierra Nevada […]

Corrected SRTM DEM

Corrected SRTM DEM

SRTM (shuttle radar topography mission) DEM (digital elevation model) is a near-global terrain product with high accuracy, and has been widely used in many researches, such as hydrological survey, geological hazards assessment, and ecological protection. However, it has been proved that SRTM DEM is systematic higher than the real ground truth in vegetation regions, as the absorption and reflection of radar signal from leaves and […]

Global forest woody residence time

Global forest woody residence time

Woody residence time is an important parameter that expresses the balance between mature forest recruitment/growth and mortality. Using field data collected from the literature, our group explored the global forest τw and investigated its influence on model simulations of aboveground biomass (AGB) at a global scale. We estimated the global 1 km τw using a random forest method by integrating the field based data, precipitation, Gross Primary […]

Global Forest AGB

Global Forest AGB

Global forest ecosystems form a large carbon pool, and are a critical component of the global carbon cycle. Accurate estimations of global forest aboveground biomass (AGB) will improve understanding of global carbon dynamics and help quantify anthropogenic carbon emissions. Light detection and ranging (LiDAR) techniques have been proven to accurately capture both horizontal and vertical forest structures and increase the accuracy of forest AGB estimation. […]

China forest AGB map

China forest AGB map

The global forest ecosystem, which acts as a large carbon sink, plays an important role in modeling the global carbon balance. An accurate estimation of the total forest carbon stock in the above ground biomass (AGB) is therefore necessary to improve our understanding of carbon dynamics, especially against the background of global climate change. In this project, we developed a new method to map wall-to-wall […]
