The significance of light climate zoning in China is briefly described.

The significance of light climate zoning in China lies in:

China has a vast territory, complex terrain and diverse climate, which can be roughly divided into five light climate zones. This division is of great significance to the architectural lighting project in China:

1. Northeast light climate area: Due to the long and cold winter and short and warm summer, the photoelectric utilization in this area has obvious seasonality.

2. Northwest Photoclimatic Zone: Because most areas in this zone live inland, the climate is dry, there are many sunny days, the air is dry and the atmospheric transmittance is high, so the photoelectric utilization has obvious regional characteristics.

3. Photoclimatic zone in North China: Because this area belongs to monsoon climate zone, it is cloudy and rainy in summer, sunny in winter, high atmospheric transparency and rich in light energy resources.

4. Photoclimatic zones in East and South China: Because this area is a monsoon climate zone, it is rich in light energy resources.

5. Southwest light climate zone: Due to the high altitude, thin atmosphere, clear sky and strong solar radiation in most parts of this area, photoelectric utilization has obvious regional characteristics.
