近日，网络上流传一则关于‘广西大明山溪水变色被污染’的视频和图文信息，引发公众关注。经广西生态环境部门及当地林业、水利等相关部门联合调查核实，该事件系误传，所谓‘溪水变色’并非由工业或人为污染造成。据调查，大明山国家级自然保护区内的溪流水体颜色变化，主要受自然因素影响。例如，雨季期间山体冲刷导致泥沙、腐殖质进入溪流，使水体呈现黄褐色；而在某些特定光照和地质条件下，溪水也可能因矿物质反射而显现出不同色泽。此外，部分网络传播内容存在断章取义、旧图新用甚至AI生成图像的情况，进一步加剧了误解。广西生态环境厅强调，大明山作为重要生态屏障和水源涵养地，长期受到严格保护，水质监测数据显示其各项指标均符合国家地表水Ⅰ类或Ⅱ类标准，未发现异常污染情况。相关部门呼吁公众理性对待网络信息，不传谣、不信谣，并鼓励通过官方渠道了解真实环境状况。目前，有关方面已对不实信息源头展开追踪，并将依法处理恶意造谣行为，以维护良好的网络生态和公众信任。
Recently, online videos and images claiming that ‘streams in Guangxi’s Damingshan Mountain have changed color due to pollution’ sparked public concern. However, a joint investigation by Guangxi’s environmental authorities, along with local forestry and water resources departments, has confirmed that this is a false rumor—the discoloration was not caused by industrial or human-made pollution.According to the investigation, natural factors are responsible for the temporary color changes in streams within the Damingshan National Nature Reserve. For instance, during the rainy season, runoff carries sediment and organic matter into the streams, giving the water a yellowish-brown tint. Under specific lighting and geological conditions, mineral reflections can also cause the water to appear differently colored. Moreover, some online posts used misleading excerpts, recycled old images, or even AI-generated visuals, further fueling misinformation.The Guangxi Department of Ecology and Environment emphasized that Damingshan, a critical ecological barrier and water conservation area, has long been under strict protection. Water quality monitoring data consistently show that the streams meet China’s Class I or II surface water standards, with no signs of abnormal contamination. Authorities urge the public to approach online information rationally, avoid spreading unverified claims, and rely on official channels for accurate environmental updates.Authorities are now tracing the origin of the false information and will take legal action against those deliberately spreading rumors to safeguard public trust and a healthy digital environment.
