In today's ecological protection red line, illegal development and construction in nature reserves, lake encirclement, deforestation and construction, mining and other ecological damage behaviors, with the increasing development of digital and intelligent technology for ecological environmental supervision, it is no longer difficult to find the above problems, and initiative, efficiency, accuracy, and intelligence have become the key words.
"When human activities cross the red line, and all kinds of mining and construction plants, digging lakes and landscaping, quarrying and sand mining, encroaching on wetlands and other behaviors damage the natural ecology, you can use the machine in front of you to quickly identify it. Pointing to a "black box" similar to a computer host, Cai Mingyong, director and senior engineer of the Land Red Line Supervision Office of the Satellite Environmental Application Center of the Ministry of Ecology and Environment (hereinafter referred to as the Satellite Center), told reporters that the machine in his mouth is an integrated terminal equipment for intelligent monitoring of human activities in important ecological spaces (hereinafter referred to as "intelligent terminals").

Ecological damage supervision takes the initiative to find clues to problems in a timely, efficient and accurate manner
Entering the working interface of the intelligent terminal, you can see four modules: refined sample production and sample library, AI model autonomous training and model library, human interference activity recognition, and intelligent interactive interpretation.

"It is only necessary to input the remote sensing images of the two phases before and after the monitoring areas such as ecological protection redlines and nature reserves into the intelligent terminal, and the built-in intelligent model algorithm can automatically identify the new or expanded human activity information within the monitoring range. Cai Mingyong said that this provides support for the analysis and judgment of regional ecological damage.
"Prior to this, the ecological protection redline ecological damage problem remote sensing initiative discovery by the state initiated, our satellite center relying on the national ecological protection redline supervision platform, regularly identify suspected ecological damage clues issued to the local, these clues after local verification and feedback, the Ministry of Ecology and Environment Department of Nature and Ecology Conservation will take the lead in organizing the subordinate technical support units, local ecological environment departments and relevant units, experts to synthesize various information, data for consultation, research and judgment, confirm the list of ecological damage problems, enter the follow-up rectification, sales stage. Cai Mingyong gave a detailed introduction to the specific process of ecological protection redline supervision.
"Nowadays, with the help of intelligent terminals, units such as the Academy of Environmental Sciences, monitoring centers or information centers, as well as inspectors, law enforcement and other regulators, can autonomously, timely and quickly monitor and find clues to ecological damage problems in the jurisdiction, and intervene and deal with them as soon as possible, without passively waiting for the list of problems, which greatly improves the initiative and efficiency of ecological environmental supervision. Talking about the original intention and advantages of the design of smart terminals, Cai Mingyong said.
Gao Jixi, chief scientist of the satellite center, said in an interview with the media that in 2023, the ecological protection redline ecological damage problem will enter the first year of "high-frequency, normalized, and full-coverage" supervision. The Satellite Center continued to promote the operational application of the national ecological protection redline supervision platform, and carried out and completed the country's first remote sensing monitoring of clues on suspected ecological damage to ecological protection redlines and three rounds of "bi-monthly" normalized monitoring.
The construction and use of the national ecological protection redline supervision platform has put the remote sensing monitoring capacity of the ecological environment into the "fast lane".
"Since the end of 2022, we have integrated the core algorithms of smart terminals into the national ecological protection redline supervision platform, and optimized the remote sensing monitoring and supervision technology system of ecological protection redlines. By the end of 2023, nearly 2,000 suspected ecological damage problems have been found in the ecological protection redline, and 225 problems have been verified and identified on the spot. Cai Mingyong told reporters.
It can be said that with the algorithm support of intelligent terminals, the remote sensing monitoring capability of the ecological environment of the national ecological protection redline supervision platform has achieved "corner overtaking". "The new technology can more effectively support the key business work of the Ministry of Ecology and Environment, such as the central ecological and environmental protection supervision and ecological protection and restoration supervision. Cai Mingyong continued.
At present, in order to achieve precise pollution control, scientific pollution control, and pollution control in accordance with the law, ecological environment science and technology have become an indispensable and important "weapon" in law enforcement. "The smart terminal is flexible and easy to use, and inspectors or law enforcement officers can use the smart terminal to conveniently and efficiently identify whether there is a suspected ecological damage problem in the target area, and the identification results can be further pushed to the on-site handheld display terminal to browse and view. ”
"Smart terminals" are more universal
At present, the national ecological protection red line has been delineated and released. Among them, the terrestrial ecological protection red line shall not be less than 3 million square kilometers, and the marine ecological protection red line shall not be less than 150,000 square kilometers.
"To achieve a redline to control important ecological spaces, it is necessary to formulate rules for the management and control of ecological protection redlines and strictly supervise ecological protection redlines. The Measures for the Supervision of the Ecological Environment of the Ecological Protection Redline (Trial) proposes that human activities are prohibited in principle within the ecological protection redline and in the core protected areas of nature reserves, and development and productive construction activities are strictly prohibited in other areas.
Cai Mingyong introduced that in order to solve the bottlenecks of low efficiency of pure manual operation, large amount of platform development, complex system deployment and operation, high hardware requirements of computer room, and poor flexibility of use in the traditional ecological environment supervision work, in order to solve the bottlenecks of low efficiency of pure manual operation, large amount of platform development, complex system deployment and operation, high hardware requirements of computer room, and poor flexibility of use in the traditional ecological environment supervision work, the National Ecological Protection Red Line Supervision Platform Project and the National Key R&D Program project "Research on Intelligent Identification Technology and Application of Human Interference Activities in Important Ecological Spaces" On the basis of other researches, combined with the experience of the construction of local redline supervision platforms, smart terminals came into being.
High-precision, all-round, and short-period are the goals of remote sensing monitoring of the ecological environment in the new era. "The design and development of intelligent terminals meet the requirements of new quality productivity, and greatly improve the application of satellite remote sensing data and the ability to detect ecological damage problems in the ecological environment department. ”
"The intelligent terminal has functions such as automatic detection of surface changes and intelligent recognition of typical ground objects, which realizes the organic integration of high-precision automatic change detection and target recognition algorithms, intelligent interactive editing tools and core business logic of human activity monitoring, and supports users to continuously carry out model optimization and upgrading according to the needs of different business scenarios to improve the accuracy of model detection and recognition. Cai Mingyong added.
It is worth noting that according to different functions and performance requirements, the satellite center has designed and developed three versions: basic, advanced and professional, and supports the deployment of "hyper-convergence + GPU cloud" mode, which "can realize the networking and distributed operation and management of multiple sets of equipment, and further improve the efficiency of monitoring and identification business operation." ”
"At present, we use smart terminals mainly to focus on ecological protection red lines and the supervision of nature reserves. "However, the application potential of smart devices is not limited to this. Cai Mingyong told reporters, "As long as it is the business needs related to the automatic detection of surface changes and the intelligent identification of typical ground objects, theoretically, the intelligent terminal can be adapted through the customization and training of samples and models, so as to support many industries such as natural resources, water conservancy, agriculture, housing and construction, emergency response, and law enforcement." ”
He said, "In the future, the intelligent terminal will continue to be optimized in the process of business application, providing stronger support for improving the ability to actively detect ecological damage, supporting the supervision and monitoring of the ecological environment, and helping to build a modern and beautiful China where man and nature coexist in harmony."
