Tourists stroll and cycle around the spot, where limpid waters, lush mountains and blooming flowers combine in weaving a picturesque scene.
The delicate blossom seen floating there is Ottelia acuminata, an aquatic plant endemic to China, which is known to have extremely strict water quality requirements. It demands high water transparency, cleanliness and calcium content, and survives only in unpolluted waters, serving as a reliable natural indicator of aquatic ecological health.
Its large-scale revival vividly testifies to Erhai Lake's remarkable ecological restoration achievements.
China's Ecological and Environmental Code, enacted on Saturday, stipulates nationwide protection and restoration of river and lake ecosystems, providing solid legal support for systematic water ecological governance across the country.
As China advances its Beautiful China initiative, this code is expected to strengthen rule-of-law guarantees for ecological protection and provide fresh impetus for the country's green and low-carbon transition.
In the early 1990s, agricultural pollution worsened Erhai Lake's water quality, causing frequent blue-green algae outbreaks. A severe algae bloom hit the lake in 1996, leaving the water turbid and smelly. As the environment degraded, Ottelia acuminata nearly disappeared from the lake.
Thanks to years of targeted ecological protection and restoration efforts, the lake's water quality has improved steadily, maintaining an excellent Grade II standard from January to June 2026, and creating favorable conditions for the return of Ottelia acuminata.
Official data show that the plant's coverage on Erhai Lake has surged from 90,000 square meters in 2021 to 950,000 square meters in 2026, marking a remarkable ecological recovery.
The improved water environment has also brought tangible economic benefits, turning the lake's ecological advantages into a sustainable industry. From lake ecology to farm cultivation and consumer products, Ottelia acuminata's dual ecological and economic value has been fully realized.
In 2018, environmental worker Zhong Lan noticed the edible plant's great potential for water purification and industrial development. With support from local authorities and Shanghai Jiao Tong University in eastern China, she started a company and built a professional research base in 2024, developing standardized planting techniques that enable high-yield, repeated harvests and offering jobs for local villagers.
Villager Li Xinyuan, who quit Ottelia acuminata cultivation years ago due to low profits, resumed planting in 2023 and earns a stable monthly salary of 4,500 yuan (about 663 U.S. dollars) at the base.
His fellow villager Du Hongquan earned over 100,000 yuan last year from growing the plant and has more than doubled his planting area this year. "The base takes full charge of sales, so we can plant without any worries," Du said.
Eryuan County, the source of Erhai Lake, now has more than 200 hectares of Ottelia acuminata plantation area, creating numerous jobs yearly. The plant has been developed into a diverse range of products like tea, plant-based coffee and cookies.
"I used to think it was exclusive to Yunnan, but I can try it elsewhere too," said a tourist surnamed Ai after tasting the plant at a hotpot restaurant in Hangzhou, east China's Zhejiang Province.
The beautiful lakeside scenery at Erhai has also boosted local tourism. In 2025, Dali received over 120 million tourist visits, attracting visitors to enjoy lake views and experience local Bai ethnic culture, with 407,000 long-term visitors.
Last month, the State Council issued a plan for building a Beautiful China during the 15th Five-Year Plan period (2026-2030), setting out the overall requirements, targets, key tasks and major projects for comprehensively advancing this initiative.
According to the plan, China will achieve overall improvement in ecological and environmental quality and make significant progress toward building a Beautiful China by 2030, with green production and lifestyles largely established and the carbon peaking target reached on schedule.
。从那时起，SpaceX利用无人驾驶的飞船回收了猎鹰9号火箭，成功回收的火箭总数达到33枚。今天的任务，称为铱-8，将把最后一颗卫星轨道为铱下一个项目。SpaceX已与铱公司签订合同，为卫星网络发射所有75颗轨道卫星，卫星网络将提供低地球轨道信号覆盖。卫星网是对铱原有卫星网的更新换代，铱原有卫星网由1997年至2002年发射的卫星组成。

C | SpaceX定期从加利福尼亚州批量发射10颗新卫星，一次只发射5颗。今天的发射将完成铱网络。大约在发射10分钟后，SpaceX努力确保其猎鹰9号火箭降落在海上的一艘无人飞船上。SpaceX去年12月的最后一次任务是为美国空军发射一颗GPS卫星。由于保密，该公司选择在发射后不回收猎鹰9号火箭。在那次飞行之前，SpaceX的猎鹰9号火箭曾试图降落在佛罗里达海岸，但不幸的是坠入了海洋。幸运的是，今天的火箭恢复非常顺利。“猎鹰9号”火箭于2018年9月从佛罗里达发射了“电星18号”华帝号卫星，并降落在大西洋的一艘无人飞船上。火箭的成功回收标志着航天公司第33次成功回收猎鹰9号火箭推进器。
