BEIJING, Aug. 2 (Xinhua) -- Chinese research teams have carried out multi-scale remote sensing joint experiments in north China's Luanhe River basin to achieve three-dimensional quantitative inversion of key ecological parameters such as soil and vegetation, according to the National Space Science Center (NSSC) under the Chinese Academy of Sciences.
Lei Yang, head of the joint experiments and a researcher at the NSSC, explained that soil and vegetation are essential components of terrestrial ecosystems, and that the physical and chemical properties of soil vary significantly with depths while the three-dimensional structure of vegetation is particularly intricate.
"The three-dimensional distribution features of soil and vegetation are crucial for ecological processes such as water and carbon cycles," Lei added.
Shi Jiancheng, a researcher at the NSSC, said the goal of the joint experiments is to overcome the limitations of traditional remote sensing, which typically operates in two dimensions.
Shi added that the experiments will offer new methods and data support for observing and understanding the material and energy cycling processes in complex ecosystems.
"These joint experiments will provide essential research data for three-dimensional remote sensing modeling of layered soils and complex vegetation, precise inversion of soil physical and chemical properties, and coordinated inversion of soil temperature and moisture," said Lei.
Lei also noted that it will offer practical examples for developing advanced three-dimensional ecological sensing satellite monitoring products. ■
