中文摘要：

利用上海市奉贤大学城内的涡动相关通量观测站点,基于Hsieh和Kljun模型对研究区内的碳通量贡献区进行了分析。结果表明：1）随着大气稳定度的增加,各风向上的碳通量贡献区范围有增加的趋势;2）当大气处于稳定条件下时,非主风向上的碳通量贡献区范围要大于主风向;3）当大气处于不稳定状态时,主风向和非主风向上的碳通量贡献区范围相差不大;4）在各风向和各大气稳定度上Hsieh和Kljun模型所输出的碳通量贡献区范围数值不同,但无显著差异,碳通量贡献区范围形态近似椭圆;5）Hsieh和Kljun模型输出的垂直于主风向和非主风向上的碳通量贡献区的长度无显著差异;6）在迎风向上Hsieh和Kljun模型的碳通量贡献峰值所处的位置有显著差异。

英文摘要：

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.
