| 中文摘要: |
| 采用无线传感器网络(WSN)实时监测法,在临安区森林部署多节点环境因子采集系统,收集2024年3月1日—12月27日的数据,以FBEM生态系统模型模拟冠层光合作用与生态系统呼吸的碳循环过程,利用全局莫兰指数评估净生态系统碳交换量(NEE)的空间自相关性。结果表明:监测期间森林整体呈碳汇功能,5月碳吸收能力最强,日均NEE为-266μmol/(m2·s),春、夏、秋季日均NEE分别为-167μmol/(m2·s)、-058μmol/(m2·s)、-023μmol/(m2·s) ,该估算结果与涡度相关法观测数据吻合;研究区东部NEE均值显著高于西部,且呈现一定的空间聚集特征。 |

| This study established a multi node environmental factor collection system in the forest of Linan District to collect the data from March 1st to December 27th 2024, by real time monitoring method with wireless sensor networks(WSN), simulated the carbon cycle process of canopy photosynthesis and ecosystem respiration by FBEN ecosystem model, and evaluated the spatial autocorrelation of net ecosystem exchange capacity(NEE) by Global Morans I. The results demonstrated that the forest served as a carbon sink during the monitoring period, with the strongest carbon uptake in May and a daily average NEE of -266μmol/(m2·s). The daily average NEE in spring, summer and autumn 〖JP2〗were -167μmol/(m2·s), -058 μmol/(m2·s)〖JP〗 and -023 μmol/(m2·s) , respectively. These estimated results were consistent with the observations by eddy covariance method. The average NEE in the eastern part of the study area was significantly higher than that in the western part, exhibiting a certain degree of spatial clustering. |
