BEIJING, Sept. 9 (Xinhua) -- Beijing imposed strict control over land use this year, with supply of no more than 6,300 hectares, compared with last year's 6,500 hectares, according to a plan released by Beijing Municipal Bureau of State Land and Resources.

Land supply for new constructions will be limited to 3,500 hectares, including 1,600 hectares for housing projects.

Two hundred and twenty hectares must be used for building houses for low-income families this year.

Land supply in downtown Beijing is supposed to be no more than 30 percent of the total, while the suburban areas will take the other 70 percent.

The plan gives priority to land use for the upcoming Olympic Games and urban infrastructure construction.
