“In the key special project of "Global Change and Response", the Ministry of Science and Technology has funded the project of "Stereoscopic Observation of Key Parameters of Global Change in Mountain Ecosystems and Development of High Resolution Products". The project is expected to propose a set of three-dimensional comprehensive observation experimental applicable technologies for key parameters of global changes in mountain ecosystems, produce 14 key parameters and high-resolution reference "true value" products for typical mountainous areas in Wanglang, form a high-resolution product production capacity for 11 key parameters, and develop the world's first high-resolution dataset product covering 7 key parameters of global mountainous areas, 25 years, month by month, and 30 meters. The research results will promote China's comprehensive monitoring capability of global mountain ecosystems, providing scientific data and technical support for the study of global changes and sustainable development in mountains.”
