Abstract: The carbon flux contribution zones (CFCZs) in the research area were analyzed by using related flux observation sites of eddy turbulence in Shanghai Fengxian University and basing on Hsieh and Kljun model. The result shows that with the increase of atmospheric stability, the scope of CFCZs in all wind directions has an increasing tendency. Under stable conditions, the scope of CFCZs in non-prevailing wind directions is larger than that in the prevailing wind direction, while under unstable state, there is no big difference in the carbon flux contribution scope in the two kinds of wind directions. In all wind directions and atmospheric stability, the CFCZs scope output by Hsieh model is different from that output by Kljun model but with no significant difference, and the CFCZs are like oval. In CFCZ lengths which are vertical to prevailing wind directions and non-prevailing wind direction, the output result by Hsieh model has no significant differences with that by Kljun model. There is a great difference in the locations of Hsieh’ and Kljun’s flux contribution peak numbers in all wind directions.
