001 Why keep planting trees every year
（为何仍需年年植树？）
Although China has the world’s largest artificial forest area, contributing about one-fourth of the global new green space, netizens’ question — "Why keep planting trees every year " — reflects the growing awareness of ecological protection. From the "green scarf" around the Taklimakan Desert to the continuous growth of both forest area and wood reserves, China’s efforts in greening are remarkable. However, challenges remain: the national forest coverage rate (25%) is still below the global average (31%), per capita forest area is only 30% of the world’s average, and resources are unevenly（不均匀的） distributed. In the dry northwest, fragile ecosystems make afforestation（植树造林） difficult, while over 50% of timber（木材） relies on imports, highlighting the country’s limited forest "wealth."
China’s forests face structural imbalances. Natural forests, rich in biodiversity, were once over-harvested, damaging their ability to recover. Meanwhile, artificial forests, though fast-growing, mostly consist of single tree species, making them weak against natural disasters. To improve quality, measures like planting native tree species and adjusting forest composition are urgently needed. Just as natural forests require time to recover, artificial forests must shift from expanding size to strengthening resilience（恢复力） through scientific management, avoiding "green bubbles" that lack long-term stability.
Every tree acts as a multi-functional ecological asset. Forests serve as "four reservoirs" — storing water, food, wealth, and carbon. With an annual carbon sink of over 1.2 billion tons (the world’s highest) and four major forestry industries each worth trillions of yuan, China proves that "green mountains are gold mountains." From the Saihanba Forest Farm to Anji’s bamboo economy, eco-friendly development benefits both people and nature. Continued greening not only improves today’s environment but also secures ecological resources for future generations, requiring equal attention to quantity, quality, and sustainable growth.
Afforestation must adapt to local conditions. In the ecologically fragile Three-North regions, expanding green barriers is key. Areas with high forest coverage now focus on improving quality, while cities use "micro-renovations" to add green spaces. Strengthening forest management ensures survival rates. Advanced technologies address challenges like water shortages in the northwest, and native tree species enhance ecological adaptability. These strategies mark a shift from "conquering nature" to "harmonizing with nature" in environmental governance.
Tree-planting is both a legal duty and a cultural practice. Over 40 years, China’s voluntary tree-planting campaign has created 50 innovative methods, from online activities to adopting ancient trees. When 1.4 billion people contribute to greening efforts, they collectively build a "green foundation" for sustainable development. By passing this responsibility across generations, China ensures lasting ecological benefits, turning lush mountains and clear waters into a shared heritage for all.

005 Chinese Researchers Develop "Golden Eye" for Drones to Boost Low-Altitude Economy
中国科研团队为无人机打造"火眼金睛"助力低空经济腾飞
The Chinese Association for Artificial Intelligence recently announced that Tianjin University's joint research project on "Key Technologies and Applications of Low-Altitude Intelligent Perception" has won the 2024 Wu Wenjun Artificial Intelligence Science and Technology Progress Award. This breakthrough addresses three major challenges in drone perception - poor visibility in bad weather, imaging inaccuracy during high-speed flight, and limited observation angles - marking significant progress in China's low-altitude economy development.
Despite drones' growing roles in disaster relief and border patrols, their practical applications have been restricted by environmental factors. Professor Hu Qinghua explained that rain, snow, and fog could reduce image recognition accuracy by up to 60%, while single drones often miss critical spatial information. The research team tackled these issues through three innovative solutions: all-weather sensing technology, self-improving algorithms (算法), and multi-drone cooperation systems.
The team established a "two-way coupling between degradation and restoration" theoretical framework, enabling clearer image recovery in complex conditions. By creating dynamic closed-loop systems and multi-sensor fusion engines, they improved target tracking precision by 6.3% during sandstorms and enhanced low-light detection capability by 13.2%. Their self-evolving perception model, trained using China's largest low-altitude visual database VisDrone and supported by Tianjin's Ascend (昇腾) computing center, addresses data blurring caused by rapid movement through real-time quality optimization.
Practical applications have shown remarkable results. Drone fleets can now locate fire sources through thick smoke during forest fires, while agricultural plant protection drones achieve centimeter-level pesticide spraying accuracy. During flood rescue operations, 30 coordinated drones successfully tracked three speeding vehicles simultaneously in heavy rain, achieving 85.6% tracking success rates.
Commercialized as both single-drone smart systems and swarm coordination solutions, these technologies have generated over 2.8 billion yuan in revenue through 340,000 equipment sales. Experts predict wider applications in smart city management and ecological protection as 5G networks expand. This innovation is expected to reshape airspace resource utilization patterns, potentially creating a trillion-yuan market in China's emerging low-altitude economy.
17. What major limitations did drones face before this technological breakthrough
A. Reduced energy consumption in extreme temperatures
B. Image recognition failures under different weather conditions
C. Limited communication range in mountainous areas
D. Overheating issues during long-duration flights
17. 答案：B 原文对应："rain, snow, and fog could reduce image recognition accuracy by up to 60%"（"雨雪雾霾导致图像识别精度骤降"）分析：选项B将原文的"bad weather"转换为"different weather conditions"，"failures"替代"accuracy reduction"。干扰项A/D涉及能源问题，C讨论通信范围，均未提及。

004 China’s Ecological Monitoring Advances Toward Intelligence
我国生态环境监测向智能化跃升
Over the past 50 years, China’s ecological environment monitoring has evolved from manual to automated methods, and now entered an intelligent phase. Jiang Huohua, director of the Ministry of Ecology and Environment’s monitoring department, stated that integrated technologies—including satellites, drones, and mobile monitoring vehicles —are being used to analyze pollutant components, track emission sources, and detect risks like cyanobacteria blooms or ecological redline violations. This "intelligent guardian system" operates around the clock, supporting modern environmental governance with "sharper eyes, keener ears, and smarter brains."
China has built the world’s largest ecological monitoring network, covering air, water, soil, oceans, and other elements. This system collects vast, accurate data to create a dynamic "panoramic view" of the environment. As a foundational project for ecological protection, it guides pollution control and evaluates the effectiveness of environmental policies.
Amid rapid advances in artificial intelligence (AI), the Ministry of Ecology and Environment has launched plans to digitize and modernize monitoring systems. For air and surface water monitoring, state-controlled stations now use "unmanned operations," cutting maintenance time by over 70%. Drones collect samples, while fully automated "dark labs" reduce labor and transport costs by 50%. Biodiversity monitoring employs infrared cameras and sound-recognition devices, achieving 85% accuracy in automated species identification. Technologies like DeepSeek are being adopted nationwide.
To strengthen technical capabilities, multiple government agencies are promoting innovation in environmental equipment. Key projects include developing monitoring robots and remote maintenance tools, while accelerating the use of digital twins and virtual reality. Integrating smart monitoring with advanced manufacturing aims to build a unified system for pollution tracking and ecological assessment.
During the 15th Five-Year Plan period, monitoring will prioritize public concerns. Plans include adding over 170 small rivers and streams near residential areas to the monitoring network, ensuring data serves community needs. By focusing on noise pollution and water quality in neighborhoods, the government aims to make environmental data more accessible and tangible, allowing citizens to directly benefit from ecological progress.

005 Chinese Researchers Develop "Golden Eye" for Drones to Boost Low-Altitude Economy
中国科研团队为无人机打造"火眼金睛"助力低空经济腾飞
The Chinese Association for Artificial Intelligence recently announced that Tianjin University's joint research project on "Key Technologies and Applications of Low-Altitude Intelligent Perception" has won the 2024 Wu Wenjun Artificial Intelligence Science and Technology Progress Award. This breakthrough addresses three major challenges in drone perception - poor visibility in bad weather, imaging inaccuracy during high-speed flight, and limited observation angles - marking significant progress in China's low-altitude economy development.
Despite drones' growing roles in disaster relief and border patrols, their practical applications have been restricted by environmental factors. Professor Hu Qinghua explained that rain, snow, and fog could reduce image recognition accuracy by up to 60%, while single drones often miss critical spatial information. The research team tackled these issues through three innovative solutions: all-weather sensing technology, self-improving algorithms (算法), and multi-drone cooperation systems.
The team established a "two-way coupling between degradation and restoration" theoretical framework, enabling clearer image recovery in complex conditions. By creating dynamic closed-loop systems and multi-sensor fusion engines, they improved target tracking precision by 6.3% during sandstorms and enhanced low-light detection capability by 13.2%. Their self-evolving perception model, trained using China's largest low-altitude visual database VisDrone and supported by Tianjin's Ascend (昇腾) computing center, addresses data blurring caused by rapid movement through real-time quality optimization.
Practical applications have shown remarkable results. Drone fleets can now locate fire sources through thick smoke during forest fires, while agricultural plant protection drones achieve centimeter-level pesticide spraying accuracy. During flood rescue operations, 30 coordinated drones successfully tracked three speeding vehicles simultaneously in heavy rain, achieving 85.6% tracking success rates.
Commercialized as both single-drone smart systems and swarm coordination solutions, these technologies have generated over 2.8 billion yuan in revenue through 340,000 equipment sales. Experts predict wider applications in smart city management and ecological protection as 5G networks expand. This innovation is expected to reshape airspace resource utilization patterns, potentially creating a trillion-yuan market in China's emerging low-altitude economy.
