Huangpu River in the Pudong section of the Expo site for visitors to enjoy a cooler environment in summer - a temperature 5 degrees Celsius lower than other parts of the site.
The organizer yesterday unveiled the design of the two main parks - the 230,000-square-meter Expo Garden and 140,000-square-meter Houtan Park - that will cover the 2-kilometer riverside.
More than 5,000 tall trees will provide shelter from the sun and provide natural air-conditioning by channeling the wind through the site, said Yu Zhiyuan, director of the Expo park project. Purified water from the Huangpu River will be sprayed on the ground to lower temperatures.
