The China International Garden Expo, hosted by the Ministry of Housing and Urban-Rural Development and the Beijing municipal government, will run from May until November and feature 46 exhibitions from 60 cities, spread over an area of 140,000 square meters.
According to the planning office, most of the construction and installation of water, electricity and telecommunication equipment will be finished by January.
The site will be linked to Beijing Subway's new Line 14, which is expected to begin operating in March.
One of the expo's focuses will be energy conservation, and a host of environmentally friendly features have been included in the park's design.
Its hot water supplies, and the heating systems in its buildings, for instance, are all based on a ground-source pump system, which will save some 1,520 metric tons of coal and reduce carbon dioxide emissions by more than 2,840 tons a year, project leaders said.
Lighting on roads and lawns, as well as monitoring systems and auxiliary backup power supplies, will be powered by solar panels.
In addition, rainfall on pavement and squares will be collected and used for irrigation, which "will greatly achieve economic, social and ecological benefits", Hua added.
An intelligent automatic control system will be used to maintain the landscape.
"The system can adjust the amounts of water used according to meteorological data and the amount of water different plants need in different seasons," Hua said.
