近日，在澳大利亚布里斯班音乐节上，一架F/A-18“超级大黄蜂”战斗机开着加力从城市中间呼啸而过。

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.

B | 在长焦镜头的压缩下，这一画面变得尤为紧张刺激。战斗机在城市中间飞行并不少见。
C | 在一些国家的节日庆典上，主办方常常邀请空军进行低空飞行和空中展示，借此将节日气氛推向高潮。这样的表演通常在空旷的场地上空进行，而布里斯班市的这次表演显然更为大胆、刺激。当F/A-18“超级大黄蜂”战斗机庞大的机体从城市楼宇间以极高的速度低空飞过时，巨大的轰鸣声和极快的速度给观看者留下强烈的感官体验。也有人被这样的场景惊吓到。美国一些民众认为这一幕很像“9·11”，隔空喊话澳大利亚民众“不要这么玩了”。显然，“布里斯班的澳大利亚皇家空军空中飞行表演画面吓坏美国观众。”澳大利亚媒体如此报道。美国空军飞行员还向民众“保证”：“这种‘场面’在美国永远不会发生。”有趣的是，邀请战斗机在节日庆典上表演的“始作俑者”，正是美国人。
D | 美国“雷鸟”飞行表演队穿越弗吉尼亚市的地标性建筑金门大桥的画面常常被美国空军对外展示，F-35战斗机的身影也不时出现在城市上空。
E | 事实上，在空旷的水域上空或城市上空进行飞行表演，其技术难度对于现代战机来说几乎为零。F/A-18“超级大黄蜂”战斗机在楼宇间的飞行照引爆人们的眼球，展现出娴熟的飞行技巧和较强的技战术性能。
F | 实际上，该机作为一款舰载机，具备良好的低空、低速性能以及较强的机动性，如此才能在狭窄的水泥丛林中飞行自如。
G | 否则，一不小心将会是机毁人亡的不堪结局。
