CO2 Concentration Characteristics in Beijing Olympic Forest Park
As one of the gases which cause the greenhouse effect, the carbon dioxide (CO2) has been a matter of concern in recent years. As the typical urban green space, Beijing Olympic Forest Park (BOFP) plays an important role in improving the regional environment quality since huge area, vegetation and biodiversity. In this paper, data of CO2-concentration from April of 2008 to January of 2009 are presented. Eleven sampling points, including nine in the BOFP and two out of the park as control, were chosen and CO2concentration was measured respectively in clear day of April, July, October of 2008 and January of 2009. The results indicated that CO2-concentration in BOFP has apparent characteristics of seasonally and daily. The main factors are attributed to the difference of photosynthesis of vegetation, respiration of vegetation. The spatial characteristics of the CO2 concentration in BOFP was presented as gradient change, This is considered to be mainly influenced by the locations, the way of plant grouping and plant community structures.
