As one of the landmarks of Singapore, Binhai Bay Garden has gradually been constructed as a city card. With its convenient transportation in the busy area of Binhai Bay, Binhai Bay Garden is a must choice for tourists to come to Singapore. The most famous of them are Flower Dome and Cloud Forest, which are the essence of the whole garden and are called plant cold rooms. The vault and the fog forest are situated together. They look like two giant hemispheres. The vault covers an area of 1.2 hectares and is 38 meters high. The temperature is maintained at 23 & #176; C to 25 & #176; C. There are seven theme gardens in the vault, which show the characteristics of plants and flowers in different areas. Cloud forest covers a little less than 0.8 hectares, and the climate inside imitates the cool and humid characteristics of tropical mountain areas 1000 to 3000 meters high. The main attraction is Cloud Mountain, which is 42 meters high. The interior is divided into several layers, each with different exhibition contents and elevators for tourists. The waterfall with a drop of 35 meters outside Yunshan provides water vapor for indoor air and increases the sense of humidity. In addition, the Optimus Tree Cluster in Binhai Bay Garden is an important energy source in the park. Photovoltaic cells are installed on the top of the tree to absorb solar energy, collect rainwater and act as ventilation pipes for the park greenhouse. Optimus tree's crown can be shaded during the day. At night, the vertical garden was beautifully decorated with colorful lights and projected multimedia. There is an aerial trail between the two trees, which makes it convenient for visitors to enjoy the beautiful scenery of Binhai Nan Garden from different perspectives. In short, Binhai Bay Garden is a high-tech ecological park showing the future of the city.
