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.
。         　　会上，国家数据局党组成员、副局长陈荣辉介绍，围绕落实公共数据资源开发利用“1+3”政策体系，充分释放公共数据价值，国家数据局开展了公共数据“跑起来”示范场景建设，累计发布了四批次共100个示范场景，今天将发布第五批次50个示范场景。         　　陈荣辉从三个方面作介绍：          　　申报数量创新高，申报方式丰富多元。

B | 今年2月，国家数据局启动了第五批场景申报工作，共收到申报方案731份，经严格评审，最终遴选出50个场景。这批场景申报延续了前四批的良好态势，申报数量创下历史新高，申报方式也更加多元，催生出部省协同、跨区域联合申报的创新模式。从申报方向看，交通运输、社会管理、医疗健康、应急管理等重点领域占比较高达到32%，充分说明深化公共数据资源开发利用，已成为各部门、各地方的广泛共识和迫切需求。值得关注的是中宣部、民政部、住建部等12个部委，以及新疆生产建设兵团等单位均为首次参与申报，标志着公共数据资源开发利用的模式机制正不断深化拓展，示范场景的影响力也在逐步扩大。

C |                         　　多源数据加速融合，数据资源供给日益丰富。第五批场景较前四批较好呈现出公共数据与社会数据、企业数据等多源数据深度融合的显著特征，特别在农业、气象、经济等领域数据融合应用需求突出，数据供给多样性持续提升。

D | 比如，在农业领域，整合农作物生长、农产品供销、冷链物流等多源数据，助力农业经营主体科学决策，促进地方特色农业精准发展和提升抗风险能力。在气象领域，将基础观测、雷达、卫星遥感等多源数据深度融合，有力支撑低空经济、防灾减灾等应用需求，大幅提升了灾害预警和风险防控能力。在经济领域，通过构建“公共数据+产业数据+金融数据”多源数据融合赋能体系，有效缓解中小微企业融资“材料多、核验繁、效率低”的痛点，让企业获得金融支持更加便捷，有效优化营商环境。         　　因地制宜特色鲜明，数据流通利用创新突破。本批次场景充分立足部门、地方资源禀赋与产业基础，以数据驱动为核心，打造了一批具有鲜明行业属性和地域特色的示范场景。东中部地区聚焦民营经济发展、低空经济、海洋经济等前沿领域先行先试，西部地区立足特色农业、沿边贸易、矿产勘探等资源优势探索差异化路径。

E | 数据开发利用模式在推动数据共享、开放和授权运营协同并进的基础上，积极探索部省协同、跨区域联动等数据流通利用方式创新。比如，在交通运输领域，通过整合京津冀三地交通数据，打造“两客一危一重”跨区域联合监管、国省干线事件协同处理等应用场景，有效提升了交通治理响应效率和执法精准度。初步探索出一条以数据跨层级、跨区域流通利用，推动区域协调发展的新路径。         　　陈荣辉表示，下一步，将深入贯彻落实国家关于加大应用场景建设和开放力度的部署要求，持续深化推进公共数据“跑起来”示范场景建设，以场景为牵引拓展公共数据资源高水平应用，让数据要素的价值更好地惠及民生福祉、社会治理、赋能产业，为数字中国建设和经济高质量发展注入强劲动力。【编辑:于晓】。
