An environmentally-friendly flower terrace design featuring the 2008 Olympics logo opened in Tian'anmen Square on August 2.

The central flower terrace with the Beijing Olympic logo in Tian'anmen Square was completed on Aug. 2.

In the spirit of a''green Olympics," the sprinkler and drip irrigation system used to irrigate the flowers recycles 30 percent of the water it uses.

A staff member said 430,000 pots of flower have been used so far and this number would increase to a million by National Day on October 1. In addition to some daily replacement, the flower terrace design will be overhauled twice before then, he added.

The flower terrace design will change to match the different themes of upcoming events. As flowers in the design of the Olympics logo presently decorate the square, the Paralympics logo replace it for the Paralympics and then a large palace and lantern design will replace that in honor of the National Day.

Staff must deal with pest control and watering after midnight each day when the Square closes. According to staff members, all pesticides are environmentally safe.
