China Completes Five-Domain Ecological Monitoring Network
China has announced the completion of a comprehensive five-domain (五基) space-air-ground integrated ecological monitoring network, marking a significant milestone in the country’s environmental surveillance capabilities. The system, reported by state broadcaster CCTV News on June 10, 2026, integrates satellite, aerial, drone, mobile patrol, and ground-based monitoring platforms into a unified ecological surveillance network.
The Five-Domain System
The network, developed by the Ministry of Ecology and Environment’s Satellite Application Center (卫星中心), combines five distinct monitoring domains:
- Space-based (天基): Satellite remote sensing — China currently operates seven ecological environment satellites in orbit, with plans to launch five more during the 15th Five-Year Plan period (2026–2030)
- Aerial-based (空基): High-tower observation platforms equipped with remote sensing equipment for continuous monitoring of specific areas
- Low-altitude drone (低空无人机): Unmanned aerial vehicles offering flexible, high-resolution monitoring that bridges the gap between satellite and ground observation
- Mobile patrol (走航巡护): Vehicle-mounted monitoring systems, including the multifunctional ecological mobile patrol vehicle equipped with AI-powered animal recognition
- Ground-based (地基): Fixed ground stations featuring audio-video sensors, infrared cameras, and four-legged robots for close-range observation
As People’s Daily Overseas Edition detailed in a May 2024 feature, the system represents an evolution from earlier “space-air-ground” monitoring frameworks. Chief Scientist Gao Jixi of the Satellite Application Center explained that the five-domain approach is not merely a collection of platforms but “a multi-dimensional, multi-node, non-linear complex monitoring network” built through equipment, data, and application coordination.
Regulatory Backing and Policy Framework
The announcement follows the implementation of the Ecological Environment Monitoring Regulations (生态环境监测条例), which took effect on January 1, 2026. According to a State Council/Xinhua News Agency report, the regulations formally mandate the construction of a “land-sea coordinated, space-ground integrated, top-bottom collaborative, information sharing” ecological monitoring network.
Satellite Application Center Director Wu Jiyou noted that the system has been under development for years, with the five-domain concept first publicly detailed in 2024. The completion milestone arrives as China positions itself as a leader in environmental surveillance technology.
AI-Powered Species Identification
A key feature of the network is its integration of artificial intelligence for species identification. Researchers have developed AI models capable of recognizing 70 species of Inner Mongolia grassland plants across 22 families and 54 genera, achieving an overall identification accuracy rate of 88.6%, according to the Xinhua report.
In Inner Mongolia, automated drone airports enable researchers to remotely control data collection from Beijing. “Staff only need to click a mouse, and the drone stationed in Inner Mongolia will take off,” Gao Jixi said, describing how the system follows preset flight paths and altitudes for automated data acquisition.
During a 2025 animal diversity survey in Xilingol, the system captured images of 34 animal species over three months, including rare species such as the steppe polecat and Eurasian eagle-owl that had not been detected through ground surveys.
Satellite Capabilities and Future Expansion
China’s satellite program forms the backbone of the monitoring network. The seven ecological environment satellites currently in orbit create a “multi-satellite coordinated” monitoring system capable of detecting habitat destruction, tracking human activities in protected areas, and monitoring major construction projects.
Wan Huawei, Director of the Biodiversity Remote Sensing Monitoring and Assessment Center at the Satellite Application Center, told Xinhua that high-frequency satellite data has proven instrumental in identifying habitat degradation. In one example from the Sanjiangyuan region, high-resolution satellite data reduced the estimated area of suitable snow leopard habitat by 28,000 square kilometers, providing more precise spatial data for conservation planning.
Implications and Outlook
The completion of the five-domain network represents a significant technological achievement aligned with China’s “Beautiful China” (美丽中国) initiative and its commitments under the Kunming-Montreal Global Biodiversity Framework. China claims this is the world’s largest ecological monitoring network.
However, the announcement comes with caveats. The primary source is China’s state broadcaster, and independent verification of the system’s full capabilities remains limited. Additionally, the integrated space-air-ground surveillance network has potential dual-use applications beyond environmental monitoring.
Looking ahead, five additional ecological environment satellites are planned for launch during the current five-year plan period, suggesting continued expansion of the network. Experts cited by Xinhua indicated that future development will focus on integrating artificial intelligence large models to further enhance monitoring capabilities, making the “heavenly eye” for ecological protection “clearer and smarter.”
As the system matures, it promises to provide unprecedented data for biodiversity conservation, ecosystem assessment, and environmental enforcement across China’s vast and ecologically diverse territory.
