Dianjiang Technology Assists Wuchao Mountain National Forest Park with Intelligent Carbon Sink Monitoring
Wuchao Mountain National Forest Park is located in Xianlin Town, Yuhang District, Hangzhou City, and is an ecological gem nestled in the foothills of the Tianmu Mountain Range. The park features undulating mountains and lush vegetation, with a maximum elevation of 494.7 metres, nurturing a rich variety of wild flora and fauna. Over 800 species of vascular plants thrive here, including 377 woody plant species such as the nationally protected tree species Xia La Mei and Xiang Guo Shu, as well as over 20 rare tree species like San Jian Shan; The animal world is equally diverse, with over 150 species of birds fluttering through the air, over 100 species of mammals roaming the area, and over 20 species of snakes slithering along, many of which are nationally protected wildlife species.
Forests, as the largest carbon sink in terrestrial ecosystems, play a crucial role in mitigating global warming through their carbon sequestration function. Forest carbon sequestration refers to the process by which forest plants absorb and store carbon dioxide from the atmosphere, thereby reducing greenhouse gas concentrations. To accurately assess this ecological function, technological support is indispensable.
In the Forest Ecosystem Carbon Sink Intelligent Monitoring Plot Project deployed at Wuchao Mountain National Forest Park, Dianjiang Technology played a pivotal role by providing core monitoring equipment. Within the plots, three-layer air carbon dioxide sensors, temperature-humidity-pressure sensors, NDVI (Normalised Difference Vegetation Index) sensors, and LAI (Leaf Area Index) sensors each perform their specific functions.
The NDVI sensor is based on remote sensing technology principles, capturing differences in reflectance between the red and near-infrared wavelength bands to accurately assess vegetation coverage and health. High values indicate dense vegetation and vigorous photosynthesis, making it suitable for mapping forest distribution, tracking forest degradation or regeneration, capturing seasonal changes, and correlating with biomass, thereby providing data support for carbon storage modelling; The LAI sensor focuses on the total single-sided area of plant leaves per unit of ground surface area. This indicator directly correlates with the forest canopy's ability to intercept light energy, influencing photosynthetic efficiency and primary productivity. Forests with high LAI values possess stronger carbon absorption capacity. When combined with data on carbon dioxide, temperature, humidity, and pressure, these sensors are used to assess the carbon sink capacity of forest ecosystems.
