Introduction
Standard Background and Significance
QX/T 354-2016 is a mandatory standard for the meteorological industry. It responds to the requirements of the State Council's "Air Pollution Prevention and Control Action Plan" and establishes a quantitative evaluation system for the first time for air pollution and safety accidents caused by fireworks and firecrackers. After the implementation of the standard, the peak concentration of PM2.5 in Beijing and other cities has dropped by 23%-35%.
Analysis of core terms
| Terms | Definition | Calculation basis |
|---|---|---|
| Meteorological Index for Fireworks and Firecrackers Discharge (WILF) | A 0-4 level index for comprehensive evaluation of suitability for discharge | max(safety, diffusion, pollution, precipitation index) |
| Grade of Air Pollution Meteorological Conditions (GPMC) | Grade of Pollutant Diffusion Capacity | QX/T 41-2006 |
| Degree of Membership (MD) | The probability that an indicator belongs to a specific level | Fuzzy mathematics algorithm |
Detailed explanation of level division and algorithm
Safety weather index calculation case
When the wind speed is 3.5m/s and the humidity is 25% in Beijing:
Wind speed membershipX1=1-(3.5/3.3)=0 (exceeding the threshold of 3.3m/s)
Humidity membershipX2=1-(25-30)/30=0.83
Safety indexY1=Level 3 (A=X1×X2=0)
Index correlation
| Index type | Key parameters | Threshold range |
|---|---|---|
| Diffusion meteorological index | GPMC level | Level 1 (excellent)~Level 5 (extremely poor) |
| Pollution meteorological index | AQI value | 0-50 (excellent)~300+ (severe pollution) |
| Precipitation meteorological index | Precipitation (mm) | 0~50+ |
Implementation recommendations
- Local adaptation: Wind speed/humidity thresholds need to be adjusted according to regional climate characteristics
- Multi-source data fusion: Combined with real-time data from air quality monitoring stations
- Warning linkage: When WILF≥Level 3, the emergency response mechanism is activated
