Based on the general survey results of urban garden of Beijing City in 2000, the VOC emission condition of urban garden greenland plants in Beijing City was studied, the natural emission inventory of VOCs in the garden greenland in Beijing City was established. The 2000 annual total emission amount was about 3.85 ?? 104C, in which isoprene was 3.09 ?? 104 C, monoterpenes was 0.59 ?? 104 C and other VOCs (OVOC) was 0.16 ?? 104 C. The emissions possessed distinct seasonal dependence in which the emission amount in summer was the largest, being 2.49 ?? 104 C, occupying 64.7% of annual emission; in winter was the lowest, being 0.0086 ?? 104 C, occupying 0.2% of annual emission. The total emission amount in urban areas were higher than that in sub-urban areas, the highest was in Chaoyang district, being 1.37 ?? 104 C, occupying 36.0% of the entire city, followed by the emissions in Haidian, Fengtai and Shijingshan districts, occupying 16.2%, 13.8%, 4.7% respectively.
