What is the scene of forest and city?

The construction of forest cities and low-carbon cities also calls for urban forests, because urban forests can directly absorb the carbon released by cities. At the same time, urban forests can reduce the frequency of air conditioning by slowing down the heat island effect and adjusting the urban climate, thus indirectly reducing carbon emissions. Urban forests not only beautify cities, but also are full of dust and automobile exhaust everywhere in many cities, which makes people gradually forget the fresh air with the smell of earth and grass. However, walking on the green street in Ganzhou and looking up at the sky, the sky is high and the clouds are light; Looking at the distance, everything is green; Breathing with your mouth open is refreshing. It seems that people live in a "forest city" in a "natural oxygen bar".
