Xizang ramps up plateau ecosystem preservation
LHASA (July 31): Yu Wenhao, project manager of an intelligent monitoring platform of the Tangbei area of Sanjiangyuan National Park, can still vividly recall the hurdles he faced while building a monitoring station right at the headwaters of the Yangtze River.
Last October, Yu and his 20-member team trekked to the remote glaciers of Mount Geladaindong in the city of Nagqu, southwest China's Xizang Autonomous Region, to erect a 15-meter-high monitoring tower at an altitude exceeding 5,300 meters.
'The journey was only about 120 km, however, it took us two days to reach the site. There were no roads!' Yu recalled.
'With approval from local authorities, we braved the freezing cold, following experienced local guides to minimise our impact on the fragile plateau ecosystem.'
The monitoring station is one of the 14 across the vast region, scattered in the Tangbei (areas under the administration of Xizang north of the Tanggula Range) area of the Sanjiangyuan National Park, as well as the Serling Co and Changtang national nature reserves.
Established in 2021 as part of China's first batch of national parks, the 190,700-square-km Sanjiangyuan National Park sits on the Qinghai-Tibet Plateau at an average elevation of over 4,700 meters.
The Sanjiangyuan region, a typical representative of the alpine ecosystem, serves as an alpine biological germplasm bank, making it a crucial ecological security barrier in China.
The Tangbei area spans 48,700 square km, accounting for roughly 25.54 per cent of the park's total area.
Since 2023, Nagqu has been developing a high-tech monitoring platform integrating satellites, drones, and ground sensors for real-time ecological tracking, according to Wang Mingqing, Party Secretary of the forestry and grassland bureau of Nagqu City.
So far, 14 stations, including the latest one that Yu's team established in October 2024, have enabled long-term, automated monitoring of wildlife, glaciers, rivers, wetlands, and ecological restoration efforts across Xizang.
'Nowadays, we continuously upgrade the platform with AI algorithms to improve wildlife identification accuracy,' Yu said.
Beyond technology, Yu highlighted growing local conservation awareness. He was deeply moved by affluent young herders volunteering to assist construction in challenging conditions, reflecting a shared commitment to conservation.
Today, over 6,000 former park residents serve as ecological rangers, transitioning from resource users to protectors.
'Thanks to advanced technology, local residents' engagement, as well as the intensive support from the country, wildlife populations in Tangbei are steadily rising,' Wang said.

Namdrol, 48, a herder from Maqu Township, Nagqu, joined an environmental protection team of the headwaters of Yangtze River in 2016.
Over the years, Namdrol and his team have voluntarily organised river cleanups, rescued trapped wildlife, and intervened to prevent environmentally harmful activities.
'We conduct five to six inspection tours every month, covering over 40 km each time. Given the extreme fragility of this ecosystem, where any damage could be irreversible, strengthening ecological protection is absolutely critical,' he said.
Xizang has always prioritised eco-environmental conservation and attached great importance to the conservation of the ecology of the Qinghai-Tibet Plateau.
It prioritises eco-environmental conservation and green development, and strives to continuously improve eco-environmental governance and protect biodiversity on the Qinghai-Tibet Plateau. Xizang has emerged as one of the regions with the healthiest ecosystems in the world.
Official statistics show that Xizang has established 47 nature reserves of all kinds, covering 412,200 square km.
The region has also rolled out an eco-compensation system to increase the income of farmers and herders and strengthen their awareness of conservation.
From 2016 to 2024, an average of 516,000 jobs for eco-environmental protection were created annually, providing an annual per capita income of 3,500 yuan (about US$489.5). – Xinhua China ecosystem nature preservation Xinhua Xizang

Smart traffic lights safeguard Tibetan antelope migration
A herd of Tibetan antelopes cross a road while vehicles stop to give way upon staff members' instruction at Hol Xil Nature Reserve, northwest China's Qinghai Province, May 27, 2024. (Xinhua/Zhang Long) XINING (July 29): In the early summer, drivers on a stretch of National Highway 109 in the Yushu Tibetan Autonomous Prefecture of northwest China's Qinghai Province often encounter a unique spectacle: herds of Tibetan antelopes crossing the busy road. In a display of harmony between nature and human activity, vehicles on the highway pull over and wait patiently, creating a temporary pause in traffic flow to allow the animals to pass safely. More recently, a high-tech 'mobile sentry' has joined this harmonious scene. Stationed by the roadside, it is remotely controlled by dedicated staff who adjust its height and angle, zoom in and out, and meticulously record the entire process of the antelopes crossing the road. Every year from May to July, female antelopes from areas such as Sanjiangyuan in Qinghai, Qiangtang in southwest China's Xizang Autonomous Region and the Altun Mountains in northwest China's Xinjiang Uygur Autonomous Region travel hundreds of kilometers to give birth in the heart of the Hoh Xil National Nature Reserve, and many need to cross the iconic National Highway 109. The mobile devices on duty for antelope migration are part of an intelligent management platform for human-wildlife conflict mitigation, which is the result of a key national research and development project. The platform utilizes traffic signals that drivers can understand at a glance, effectively indicating when to proceed or stop, which can minimize the impact of antelope migration on highway traffic and efficiently avoid the risk of collision, said Lian Xinming, head of the project and a researcher at the Chinese Academy of Sciences' Northwest Institute of Plateau Biology. 'So far, our project has collected data on 28 groups of antelopes crossing the road during their migration from wintering grounds to breeding grounds,' Lian said. Using video recordings from the mobile devices, researchers analyze the scale and speed of each antelope herd to determine the correlation between the two, providing data support for rapid traffic light response. When the platform detects antelopes approaching the road, it sends an early warning to staff at a nearby protection station, alerting them to direct traffic. Meanwhile, electronic billboards on both sides of the passage display messages such as 'Tibetan antelopes are crossing ahead, please slow down.' Once the last antelope has passed, the platform prompts vehicles to proceed. Lian noted that in situations where some antelopes do not cross the road, only cross halfway or turn back after crossing, the platform also relies on data analysis and AI recognition to rapidly judge the animals' crossing intentions, and to prevent accidents between vehicles and herds. The idea to develop traffic lights for antelope migration in the Hoh Xil National Nature Reserve had been brewing in the minds of scientists for two decades. This file photo taken on July 28, 2023 shows a herd of Tibetan antelopes crossing a road en route to their habitat in Sanjiangyuan area, northwest China's Qinghai Province. (Xinhua/Zhang Hongxiang) Back in June 2004, thanks to the call of the Green River non-governmental environmental organization and support from all sectors of society, China's first traffic lights for wildlife were installed on the Qinghai-Xizang Highway. Yang Xin, who initiated the project, remembers that whenever personnel at the observation point heard a command on their walkie-talkie, they would turn on the traffic lights on both sides of the highway where the antelopes were about to cross. The traffic police would then signal cars to pull over using standard road traffic gestures. Today, with China's advancements in intelligent machinery and other technological fields, those manual traffic lights have been upgraded to a more intelligent system. The management platform is expected to be put into use in 2027. By then, with the help of the smart traffic lights, this lifeline for antelopes migrating to breed and deliver their young will operate more safely and smoothly, Lian said. Under first-class state protection in China, the once-endangered Tibetan antelope is mostly found in Xizang, Qinghai and Xinjiang. The species' population has increased over the past three decades thanks to a ban on illegal hunting and measures implemented to improve habitats. – Xinhua antelopes China fauna traffic lights

China's R&D-to-market pipeline emerges as global innovation magnet
A staff member (R) of Westwell, a Chinese technology company, introduces a Q-Tractor P40 Plus new energy unmanned vehicle to a visitor during its debut at the 2025 World AI Conference in east China's Shanghai, July 27, 2025. – Xinhua photo BEIJING (July 29): For Liu Qing, director of the National Innovation Center par Excellence (NICE), the first half of 2025 has been an exceptionally busy but rewarding period to expand China's global research footprint. Through efforts like hosting science and innovation forums in countries including Denmark and Australia, the center added 11 new overseas strategic partners during the six months, bringing the total number of its international partners close to 100. 'The market prospects for industrial development in China are indeed attractive to overseas scientists,' said Liu, while speaking on the latest episode of China Economic Roundtable, an all-media talk show hosted by Xinhua News Agency. 'They see it as a place to truly make their results serve humanity.' Behind the center's successful global push lies China's rapidly advancing innovation ecosystem — which puts emphasis not only on research and development (R&D), but also on the commercialization and industrialization of new technologies. Official data showed that China's R&D expenditure exceeded 3.6 trillion yuan (about 503.73 billion U.S. dollars) in 2024, ranking second in the world. Notably, enterprises played a key role in driving such innovation. Data reveals that the corporate sector contributes over 75 percent of national R&D spending and employs more than 75 percent of R&D personnel. These expenditures have turned into tangible breakthroughs. In the fields of quantum technology, life sciences and artificial intelligence, China saw significant recent progress — with many of its industries leading the world. 'Our innovations fuse scientific discovery with industrial capability,' said Gao Qianfeng, co-founder and vice president of GalaxySpace, a Beijing-based commercial space firm. For Gao, the secret behind turning scientific breakthroughs into commercialized products lies in China's robust industrial ecosystem. Noting that the space firm's supply chain spans over 1,000 partners across enterprises, universities and research institutions, Gao said that navigating this extensive ecosystem requires deep collaboration. 'Open collaboration creates catalytic chemistry between labs and factories,' Gao explained. Policy frameworks reinforce this integration. Gan Xiaobin, an official with the Ministry of Industry and Information Technology, said global evidence shows that advanced sci-tech services catalyze deeper industry-academia convergence. Earlier this year, China released an implementation guideline on accelerating the high-quality development of the science and technology services sector — which outlined specific tasks across key areas such as R&D, technology transfer and commercialization, business incubation and technology promotion. The ministry will work with other government departments to accelerate the transformation of research into market-ready products to seed emerging industries, Gan said. Looking forward, Liu of NICE said sustained progress requires increased basic research spending. 'Scientists need to have enough funding to dedicate their time to a single field for three to five years to yield truly groundbreaking discoveries,' he said. This commitment, coupled with robust industrial strength and global outreach, will continue to position China as a central player in global innovation, the experts said. China innovation market RD
