Abstract:
This report reviews the current natural resource survey and monitoring system in terms of its support for carbon source and sink assessment. Based on land-use change survey data, and integrating data from forest, grassland, and wetland surveys, remote sensing, meteorological stations, as well as socioeconomic, energy, and population statistics, a land-use-based carbon source/sink accounting framework is constructed. Spatial mapping of carbon sources and sinks across national territory is carried out, and a multi-source data fusion-based carbon budget accounting workflow is established to support the optimization of regional land-use spatial patterns.
In addition, the report explores methods for estimating carbon stocks in forest ecosystems at fine spatial scales. Carbon stock estimation models are developed for different tree species by integrating high-density point cloud data and multispectral remote sensing imagery, enabling large-scale mapping of forest carbon stocks. These efforts contribute to the development of an operational system for the survey, monitoring, and assessment of ecosystem carbon sinks.
Biography:
Wei Hou, Research Fellow, currently serves as the Deputy Director of the Research Center for Natural Resources Survey and Monitoring at the Chinese Academy of Surveying and Mapping (CASM). He obtained his Ph.D. in Geographic Information Science from Technische Universität Dresden, Germany, in 2014, and joined CASM in 2015. In 2021, he was selected for the “High-Level Science and Technology Innovation Talent Program” by the Ministry of Natural Resources (MNR) as a Young Science and Technology Talent, and was recognized as a Young Academic Leader of CASM. His research focuses on natural resource survey and monitoring, ecological security pattern simulation and optimization, and spatial accounting of carbon balance in land use. Dr. Hou has published over 40 academic papers, including 20 SCI-indexed articles as first or corresponding author. He is the author of two monographs and co-author of two additional books. He has received multiple Science and Technology Progress Awards from the China Association for Geographic Information Society, including First Prize (2018, ranked 4th; 2023, ranked 2nd) and Second Prize (2019, ranked 5th). He holds 13 authorized patents and 4 software copyrights, and has participated in the formulation of one national and one industry standard.
