标题 中国天胡荽属植物的订正

Based on the real observation data, forecast equitation or forecast model, the dynamics method such as divergence and vorticity calculation, real data correction, ascending and subsidence calculation was used to simulate the 4D field of divergence, vorticity and vertical velocity at different time, different range and different levels. The field was connected to 3D fields of insect trajectories, yielding the flying speed, direction, ascending area and subsidence. Thus the peak of immigratory insect could be timely monitored. A system of the peak of immigratory insect forecast was set up.

根据实际观测资料、数值预报方程或数值预报模式等输出的风场网格化处理结果,利用运动学方法、散度推算法、涡度推算法、实际资料订正法、升降法等对不同时间、不同范围、不同层次的四维散度、涡度和垂直运动速度场进行计算或模拟,将计算或模拟得到的散度场、涡度场、垂直运动速度场与昆虫迁飞的三维气流场联系起来,得到该类昆虫所具有的迁飞速度、方向、上升区和下降区,从而对昆虫的迁入峰进行实时预警。

In this study, based on the Rnl, extinction coefficient k, transition coefficient of canopy layer stomatic resistance K', aerodynamics resistance ra and rc calculated with the data of Rn, LAI, rsi, the daily transpiration variation of Picea purpurea, Larix principisrupprechtii, Hippophae rhamnoides ,Betula platyphylla and Populus cathayana were studied in Datong County, Qinghai Province. Comparing with the practical transpiration variation measured by Li1600 Steady Porometer, the relative error of this model was less than ±15%, and the results were stabilized and tested by precision analysis.

本研究通过对Rn、LAI、rsi的实地观测,确定了林冠截流净辐射、消光系数、冠层阻力转换系数、空气动力学阻力和冠层整体气孔阻力,对青海大通地区紫果云杉、华北落叶松、沙棘、白桦和青杨的日蒸腾过程进行了模拟,与用快速称重法订正的Li1600稳态气孔仪实测蒸腾结果对比,模拟的相对误差在±15%以内;模型敏感性分析发现,温度、LAI以及rsi是决定模拟结果的主要参数,模型对各参数变化反应不敏感。
