Quick answer：Roof greening in China refers to the practice of cultivating greenery on rooftops, which is a popular and innovative approach to urban greening. It involves planting various types of plants on the roof to create green spaces. This method helps to improve air quality, reduce urban heat island effect, and increase biodiversity. Some famous roof greening projects in China include the Green Roof Park in Nanjing and the Shanghai World Financial Center, which has a green roof covering its observation deck.
