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.

北京时间4日凌晨，2022年世界游泳锦标赛在布达佩斯落下帷幕。在最后一个比赛日中，中国选手陈艺文携手昌雅妮拿到女子双人3米板冠军，杨健、杨昊分获男子单人10米台金牌、铜牌。至此，以老带新的中国跳水队包揽本届世锦赛跳水项目全部金牌，总奖牌数收获13金2银2铜。

C | 本届赛事过后，中国跳水队斩获的世锦赛金牌总数升至108枚。加上此前结束的花样游泳和游泳等项目，中国队在本届世锦赛共收获18金2银8铜，金牌数量也创下中国队在历届世锦赛的最佳战绩。包揽金牌，海外首次“随着女子双人3米板和男子单人10米台的金牌被中国选手摘得，中国队席卷本届世锦赛所有跳水金牌。”法新社4日如此评论。这并非中国跳水队首次在单届世锦赛上未有一金旁落：2011年上海世锦赛，中国队当时就摘得全部10枚金牌。而达成世界大赛百金，在中国只有乒乓球、举重和跳水三支国家队来到这一高度。本届世锦赛是中国跳水队在巴黎奥运周期参加的首场国际大赛。

D | 登上本届世锦赛最高领奖台的中国跳水选手中，有成名已久的老将曹缘，有东京奥运会冠军全红婵、王宗源、陈芋汐，有世界冠军杨健、杨昊、练俊杰、陈艺文、昌雅妮、任茜、林珊，也有李亚杰、白钰鸣、朱子峰、段宇、郑九源等首次亮相世锦赛赛场的新人。

E | 他们首次亮相世锦赛2002年出生的李亚杰，在本届世锦赛女子1米板决赛中封后。

F | 李亚杰参加过2019年第二届全国青年运动会，斩获男女混合3米板冠军、女子1米板亚军。2021年全国跳水冠军赛上，她又以318.35分的总成绩刷新近年来中国选手在女子1米板上的得分新高。

白钰鸣搭档全红婵获得本届世锦赛混合全能冠军，两名15岁小将为中国跳水队夺得自从1982年参加世锦赛以来的第100枚金牌。白钰鸣在去年全运会上进入公众视野，当时他在青年组和成年组比赛中斩获两金两铜，还在成年组男子单人10米台决赛中获得第5。在本届世锦赛混双3米板决赛中夺冠的林珊/朱子锋也是“00后”。这是林珊自上届世锦赛混合全能项目夺冠后，第二次摘得世锦赛金牌；2002年出生的朱子锋首次参加世锦赛便获得世界冠军，去年全运会他参加了男子10米台单双人和跳水男子团体的比赛，代表广东队赢得跳水男子团体冠军。16岁的段宇同样是首次参加世锦赛就斩获金牌，他与任茜搭档赢得本届世锦赛混双10米台的冠军。在动作难度并不突出的情况下，两人的默契度和动作完成质量高出对手一筹。段宇此前拿过国际泳联跳水大奖赛男子10米台冠军、2018年全国跳水锦标赛混双10米台冠军。18岁的郑九源是此次世锦赛上唯一未获得奖牌的中国跳水选手，他在男子1米板比赛中获得第8。夺冠并非无悬念除了新人，本届世锦赛还有多位中国跳水选手荣膺“多金王”。

G | 王宗源独揽男子单人、双人3米板和男子1米板3枚金牌，陈芋汐赢得女子单人、双人10米台双金，全红婵则是混合全能和女子双人10米台两金在手，陈艺文获得女子单人、双人3米板两项冠军。成绩之外，也有隐患。

H | 男子双人3米板冠军组合曹缘／王宗源在决赛最后一跳出现失误，差点让英国组合拉弗尔/哈丁翻盘。国际泳联官网评论称，中国队的夺冠过程并没有如预期那样毫无悬念。在部分单人项目上，国外一些极具实力的选手也发起冲击。女子3米板和男子10米台两个项目上，银牌均由外国选手获得：加拿大名将瓦莱获得女子3米板亚军，15岁的日本选手玉井陆斗获得男子10米台亚军。国际泳联官网4日称，中国赢得全部13枚跳水金牌，但最后一枚男单10米台的金牌差点溜走，获得亚军的日本新秀玉井陆斗给中国选手杨健、杨昊制造了很大的麻烦。
