喜马拉雅山烟花秀引争议，记者探访：三天后现场仍有痕迹

Core Viewpoint - The outdoor brand's "Shenglong" art fireworks event in Tibet has sparked public concern regarding its potential environmental impact on the fragile ecosystem of the Tibetan Plateau [1][10]. Environmental Impact - The fireworks display lasted 52 seconds and involved the ignition of 1,050 fireworks, with the event taking place at an altitude of 4,500 meters where the primary vegetation is alpine meadow [3][10]. - Although the event was not held in a protected area, it was located approximately 30 meters from the nearest water body and 6 kilometers from the nearest glacier, raising concerns about its proximity to sensitive ecological zones [3][10]. - Local officials stated that the fireworks used biodegradable materials, which were previously verified to meet environmental standards in various international locations [11]. Ecological Concerns - Experts highlighted that the alpine meadow is a fragile ecosystem, with a soil layer only 10 to 20 centimeters thick, making it susceptible to erosion and difficult to restore after disturbance [12]. - The noise generated by the fireworks could disrupt local wildlife, particularly small animals like the plateau pika, which may struggle to survive the winter due to stress from the event [14]. - The local ecological environment requires a scientific and effective long-term monitoring and assessment mechanism to evaluate the lasting impacts of the fireworks on vegetation, wildlife, and water bodies [14]. Regulatory Response - The local government has formed an investigation team to assess the situation and ensure compliance with environmental laws, including the Grassland Law and the Wildlife Protection Law [9]. - The event had received prior approval from the ecological environment bureau, which deemed an environmental assessment unnecessary due to the use of eco-friendly materials [7].
