CCTV News:The reporter learned from National Forestry and Grassland Administration that the comprehensive monitoring results of forest and grass ecology in China show that the forest area and accumulation in China have increased steadily, and the total amount of forest and grass resources has increased steadily, and the ecological management of forest and grass has achieved remarkable results.
National comprehensive monitoring of forest and grass ecology is a survey and monitoring work of forest and grassland wetlands jointly organized by National Forestry and Grassland Administration, Ministry of Natural Resources, and implemented by National Forestry and Grassland Administration as a whole. The main monitoring contents include forests, grasslands, wetlands, deserts, forest and grass carbon sinks, etc. It is a comprehensive monitoring of various forest and grass resources and ecological conditions.
In 2022, more than 20,000 investigators were invested nationwide, and 459,000 sample plots were monitored by remote sensing, 57,000 sample plots were surveyed on the ground, and 520 million map spots were monitored. The monitoring results show that China’s forest area and stock have increased steadily, the total amount of forest and grass resources has increased steadily, the quality has been continuously improved, the ecological function has been continuously enhanced, the carbon sink capacity of forest and grass has continued to increase, and the ecological management of forest and grass has achieved remarkable results.
Through the comprehensive monitoring of forest and grass ecology in China, the protection and development of forest and grass resources can be achieved, which provides an important foundation for China to promote large-scale land greening, comprehensive desertification control and key ecological projects such as "Three North", forest length system supervision and assessment, integrated protection and systematic management of mountains, rivers, forests, lakes, grass and sand, and the implementation of peak carbon dioxide emissions and carbon neutrality strategies.
Various technical means to improve the accuracy of monitoring
The comprehensive monitoring of forest and grass ecology in China has comprehensively applied various technical means such as remote sensing to continuously improve the accuracy of monitoring.
The national comprehensive monitoring of forest and grass ecology is based on the "three-tone" data of the national territory, docking with the "one map" of national forest resources management, and integrating the thematic information of forests, grasslands, wetlands and deserts, and establishing a national forest and grass resources database covering spatial location, management attributes, natural elements and resource characteristics information.
In 2022, a total of 459,000 plots were monitored by remote sensing, 57,000 plots were surveyed on the ground and 520 million patches were monitored.
Through the analysis of the map spots, it is found that in the past ten years, the forest coverage rate of Beijing has increased from 35.84% ten years ago to 43.31% now, that of Guizhou has increased from 37.09% ten years ago to 43.81% now, and that of Hunan has increased from 47.77% ten years ago to 53.03% now. Compared with ten years ago, the scope of green spots in these provinces is getting wider and wider. Behind this, it reflects the fruitful achievements made by China in vigorously promoting land greening and afforestation.
