AI Summary & Key Points
Summary
The article reports an unfounded video circulating online claiming that Jiuzhaigou's lake water appears blue only due to pigment dyeing. The Jiuzhaigou Administration issued a solemn statement clarifying that the video was not filmed within the scenic area and that the dyeing claim is pure rumor. The article cites expert science popularization by Researcher Sun Geng from the Chengdu Institute of Biology, Chinese Academy of Sciences, explaining from physical, chemical, and biological perspectives the causes of the blue-green color of Jiuzhaigou's Five-Color Lakes: high water transparency, calcium carbonate particles scattering blue-green light, and secondary reflection by algae jointly producing the color. At the end, the article calls on netizens to discern the authenticity of online short videos, not to believe or spread rumors, and to jointly safeguard the reputation of the world natural heritage and a clean online environment.
Main Points
* 1. The blue-green color of Jiuzhaigou's lake water is determined jointly by natural physical, chemical, and biological factors.
High water transparency, efficient scattering of blue-green light by calcium carbonate particles, and secondary reflection by algae jointly produce the lake's blue-green color, with no artificial pigment intervention throughout.
* 2. The online dyeing video is false information; its filming location is not within Jiuzhaigou.
The Jiuzhaigou Administration's statement clarified that the video was not filmed inside the scenic area, the dyeing claim is pure rumor, and it has debunked the online misinformation.
* 3. Officials urge the public not to believe or spread rumors, to maintain the online environment.
Reminding netizens to discern the authenticity of short videos, to avoid damaging the reputation of the world natural heritage, and to jointly safeguard Jiuzhaigou's natural heritage reputation and a clean online environment.
* 4. The article cites a researcher from the Chinese Academy of Sciences to provide scientific basis, enhancing credibility.
Researcher Sun Geng explains the lake's color formation from physical, chemical, and biological perspectives, providing authoritative science popularization support for the debunking.

据四川观察7月15日报道，近日，网络流传“九寨沟湖水依靠颜料染色才呈现蓝色”的不实视频，误导不少游客，损害景区形象。
为此，九寨沟管理局就此发布严正辟谣声明，澄清视频拍摄地点并非九寨沟，网传染色说法纯属虚假谣言。
作为世界自然遗产、世界生物圈保护区，九寨沟五彩湖水是天然地质光学奇观，有完整科学依据支撑，全程不存在任何人工颜料干预。
中国科学院成都生物研究所研究员孙庚对此作出专业科普，九寨沟湖水独有的蓝绿色，由物理、化学、生物三重因素共同造就。
从物理层面看，九寨沟高山湖泊水质洁净，水中悬浮物、浮游生物含量极低，水体透明度极高。太阳光包含红、橙、黄、绿、蓝、靛等光线。红、橙、黄等长波长光易被水体吸收，蓝、紫等短波长光线更容易被散射，湖水因此呈现出鲜明蓝调。
从化学层面看，流域水体富含钙、镁、碳酸氢根等离子，相互结合形成0.1至0.45微米的钙华微小颗粒，这类颗粒能够高效散射蓝绿光，进一步强化湖水艳丽色彩。
同时，湖内藻类等水生生物会对光线进行二次反射，丰富水体色彩层次。
除此之外，湖泊水深、四季更迭、阴晴天气、观赏视角不同，都会让湖水呈现出深浅不一的渐变色彩，造就九寨沟变幻灵动的水景特色。
九寨沟管理局提醒广大网友，不要随意编造、转发虚假谣言，恶意诋毁世界自然遗产声誉，面对网络短视频信息注意辨别真伪，不信谣、不传谣，共同守护九寨沟自然遗产口碑与网络清朗环境。如需了解景区自然景观相关知识，可关注景区官方发布的权威科普内容。

Key Quotes
> Jiuzhaigou's Five-Color Lakes are a natural geological optical wonder, supported by complete scientific evidence, with no artificial pigment intervention throughout.
> The unique blue-green color of Jiuzhaigou's lake water is jointly created by physical, chemical, and biological factors.
> Do not casually fabricate or forward false rumors, maliciously slander the reputation of world natural heritage; when facing online short video information, discern truth from falsehood, do not believe or spread rumors, and jointly safeguard Jiuzhaigou's natural heritage reputation and a clean online environment.
> From a physical perspective, Jiuzhaigou's high-mountain lake water is clean, with extremely low levels of suspended matter and plankton, resulting in extremely high water transparency.
> From a chemical perspective, the basin's water is rich in calcium, magnesium, bicarbonate ions, etc., which combine to form calcium carbonate particles measuring 0.1 to 0.45 micrometers; these particles efficiently scatter blue-green light, further enhancing the lake's vivid color.
