National Forest Resource Management "One Map" with Multiple Methods to Improve Data Precision Database Monitoring Ecology | Forest and Grassland | Data
CCTV News: The reporter learned from the National Forestry and Grassland Administration that the comprehensive monitoring results of forest and grass ecology in China show a steady increase in forest area and volume, a steady increase in the total amount of forest and grass resources, and significant achievements in forest and grass ecological governance.
The national comprehensive monitoring of forest and grassland ecology is a forest, grassland, and wetland investigation and monitoring work jointly organized by the Ministry of Natural Resources and the National Forestry and Grassland Administration. It is coordinated and implemented by the National Forestry and Grassland Administration, and the main monitoring content includes forests, grasslands, wetlands, deserts, forest and grassland carbon sinks, etc. It is a comprehensive monitoring of various forest and grassland resources and ecological conditions.

In 2022, more than 20000 investigators were deployed nationwide to complete remote sensing monitoring of 459000 plots, ground surveys of 57000 plots, and monitoring of 520 million patches. The monitoring results show that the forest area and volume in China are steadily increasing, the total amount of forest and grass resources is steadily increasing, the quality is continuously improving, and the ecological function is constantly enhancing. The carbon sequestration capacity of forest and grass continues to strengthen, and the effectiveness of forest and grass ecological governance is significant.
Through the comprehensive monitoring of national forest and grass ecology, the effectiveness of forest and grass resource protection and development can be presented, providing important basic support for promoting large-scale land greening, comprehensive desertification prevention and control, key ecological engineering construction such as the "Three North", forest chief system supervision and assessment, integrated protection and systematic governance of mountains, rivers, forests, fields, lakes, grasses and sands, as well as implementing carbon peak and carbon neutrality strategies in China.

Multiple technological means to improve monitoring accuracy
The comprehensive monitoring of national forest and grass ecology has comprehensively applied various technological means such as remote sensing, continuously improving the accuracy of monitoring.

The national comprehensive monitoring of forest and grassland ecology is based on the national land "three surveys" data, connected with the national forest resource management "one map", integrating thematic information on forest, grassland, wetland, desert and other map areas, and establishing a national forest and grassland resource database covering spatial location, management attributes, natural elements, and resource characteristics information.
In 2022, a total of 459000 remote sensing monitoring sites, 57000 ground surveys, and 520 million patch monitoring sites were completed nationwide.

Through analyzing the patterns, it was found that in the past decade, Beijing, Guizhou, and Hunan have seen a significant increase in forest coverage. Beijing's forest coverage has increased from 35.84% ten years ago to 43.31% today, Guizhou's forest coverage has increased from 37.09% ten years ago to 43.81% today, and Hunan's forest coverage has increased from 47.77% ten years ago to 53.03% today. Compared to ten years ago, the scope of green patches in these provinces is becoming wider and wider. Behind this, it reflects the fruitful achievements of China's vigorous promotion of national greening and afforestation.
