- 摘要:
- SiB2 （simple biosphere model Version 2）是用来模拟生态系统通量较为理想的国外模型，为了探讨其在我国黄河灌区的适用性及利用遥感数据驱动模型的可行性，并用其来研究该地区农田能量收支情况，以位山灌区为研究试点，利用位山实验站1 a左右的观测数据对模型进行了验证分析，模拟结果表明：SiB2模型能够较好地模拟位山试验站农田的能量通量、CO2通量及地表温度，净辐射、潜热通量、感热通量、CO2通量与地表温度的模拟值与观测值吻合较好，线性相关系数R分别为0.988，0.714，0.607，0.677与0.933，其中净辐射模拟效果最好，感热通量偏差较大。另外，利用遥感MODIS LAI数据驱动SiB2模型表明，除净辐射外，模拟效果很差，因此在站点尺度遥感LAI（叶面积指数，leaf area index） 产品不适合驱动SiB2模型。
- Abstract:
- SiB2 (simple biosphere model Version 2) can be used to simulate the dynamic change of the flux of water, heat and carbon. In order to discuss its applicability in plain for our country, this paper simply introduced the structure and control equations of SiB2 at first, and then used it to simulate the surface energy budget in Weishan irrigation area based on the data of Weishan observation station. The results showed that the simulated net radiation, latent heat flux, sensible heat flux and CO2 flux were shown to be basically in agreement with observations with their linear correlation coefficient being 0.988, 0.714, 0.607, 0.677 and 0.933 respectively. In addition, the simulated value of sensible heat flux and CO2 flux were higher than the observed value and the simulated net radiation and latent heat flux were lower than the observed ones. In addition, MODIS LAI products were used to drive the model and found that the simulation results were not satisfactory except net radiation. Therefore, at the observing site scale, the remote sensing MODIS LAI products are not suitable for driving SiB2 model.
