Green transformation

As a member of the sub city-center's management team, Hu has witnessed firsthand the rapid development of the area in recent years.

At the heart of the 155-square-kilometer core area of the center lies the Central Green Forest Park, which is planned to eventually cover a total area of 11.2 sq km.

"The changes in the ecological environment are particularly noticeable," Hu said. "The site of the Central Green Forest Park was previously a chemical plant and three surrounding villages. In the past, there was also some soil contamination."

Environmentally sensitive methods were used during the rehabilitation and enhancement of the site, Hu said.

"Trees and plants in the former villages were relocated for the construction of the park," he said. "All the planting was designed based on keeping existing trees, rather than removing them all and planting new ones."

After the completion of work on the park, the authority invited the former villagers to inspect it. "They could recognize the trees which had been in front of their former homes," Hu said. "The development of the city is a good thing and we also want to keep their memories alive."

In March, the park was recognized at the national level as one of the first 23 cases in China of an energy-efficient, green, and low-carbon transformation project, the National Energy Administration said.

The park not only features photovoltaic panels, geothermal heat pumps, power storage and green energy, but also green buildings, charging piles, ecological restoration work and smart management systems. These diverse low-carbon applications are good examples that can be easily adopted across the country, the administration said.

By 2025, the park's energy terminals are expected to be entirely powered by green energy, achieving the goal of zero carbon emissions, according to the Beijing Investment Group, the operator of the park.

"It is different from traditional parks in the country, it is one without walls," Hu explained. "We hope to integrate the city and the forest park, providing residents with a better experience. During the road planning phase, we carefully designed the routes … to avoid conflicts between motor vehicles and pedestrians.

"Since its opening in September 2020, visitors have highly praised the park, and I often visit it myself," he said.
