中國空氣品質警報

中國空氣品質好嗎？

截至2026年11月4日，中國部分地區空氣品質較差，主要城市空氣品質處於 不健康 範圍和高 PM2.5 嚴重危害居民尤其是兒童和老人的健康。

到下午 4:00（中國標準時間，GMT+8），一些城市中心記錄的 AQI 讀數在 100 到 200 之間，引發了健康警告。建議居民限制戶外活動，關閉窗戶，外出時戴口罩，在室內使用空氣清淨機。

雖然條件仍較差， 2025年中國PM2.5平均濃度為29.6微克/立方公尺，相當於AQI為87，屬於「中」。這一水準比世界衛生組織年度指引值 5 µg/m3 高出近 5.92 倍，使 中國躋身 2025 年全球污染最嚴重的 20 個國家之列.

When will the air quality improve in China?

China’s PM2.5 concentrations follow a well-documented U-shaped seasonal pattern, peaking in winter from December through February and reaching their lowest point in summer. This seasonal deterioration typically begins in October, as autumn cooling and increasing stagnation begin to raise air pollution across China ahead of the official coal-fired heating season starting November (1).

Short-term improvement depends on wind, rain, and stronger atmospheric mixing. Lasting progress depends on continued enforcement of China’s clean energy transition and emission controls (2).

What is causing poor air quality in China?

The root causes of air pollution in China include dependence on fossil fuels, coal combustion, biomass burning, traffic and waste incineration emissions, industrial pollution, and soil dust, with coal and other fossil fuels exploited despite renewable investments (3).

As temperatures drop, residential coal combustion becomes the dominant driver of PM2.5 across China, contributing approximately 46% of concentrations in the Beijing-Tianjin-Hebei region. Temperature inversions and air stagnation further trap emissions from coal-fired power plants, industrial zones, and vehicle exhaust near the surface, amplifying pollution across major cities (4).
