| 摘 要： | 本文基于ChinaFLUX的定位观测数据,研究了二种典型森林生态系统、二种典型草地生态系统和一种典型农田生态系统碳固定价值年内流量和累积过程。研究结果揭示了不同类型生态系统碳固定价值总量的差异,以及价值流量过程和累积曲线的不同变化趋势。5种生态系统按碳固定年价值由大到小的排序为：禹城〉千烟洲〉长白山〉海北〉当雄。千烟洲碳固定日价值和月价值年内变异最小,其次为长白山,禹城再次之,年内变异最大的为当雄和海北。5种生态系统碳固定日价值的累积过程都能很好地拟合为三次方曲线。

| Abstract: | Based on data from ChinaFLUX this study analyzed the daily value flow processes of carbon fixation, monthly value distribution, and daily accumulative processes in a year of two kinds of typical forest, two kinds of grasses and a farmland. The results showed that the annual value of carbon fixation of these ecosystems was different, and flow processes and cumulative processes followed different trends over a year. The sequence of the five kinds of ecosystems based on the annual value of carbon fixation from... |
