| 摘 要： | 研究了向海湿地贴地气层中CO2浓度8月份的日平均值在水平方向及垂直方向上的空间分异特征.结果表明,向海湿地贴地气层CO2日平均浓度在246~266mol/mol之间,低于三江平原湿地贴地气层乃至全球CO2浓度值,4个高度(0.1,0.6,1.2,2m)水平方向纬度分异显著,变异显著区基本一致;垂直分异差异显著,芦苇和香蒲湿地变异最大,岸边坡地变异最小.

| Abstract: | We have studied the spatial variance character of ambient CO2 daily average concentration of august above Xianghai natural reserve wetland in horizontal and vertical directions. The results show that the concentration ranges from 246 to 266mol/mol, lower than that above Sanjiang Plain wetland as well as that above the globe; the latitude variance in four levels of height (0.1, 0.6, 1.2 and 2m) in the horizontal direction is distinct, and the areas with distinct variance are consistent basically; the vertical variance is evidently different with the reed and the cattail wetlands the greatest and the land on the shapes near bank the smallest. |
