查询词典 canopy

Also,we found that the daily average value of WUEe always higher than that of leaf level WUE,one reason maybe lie in that they can not be compared directly for using two kinds of different measurement methods,the other reason may be associated with the energy fluxes underestimate by EC technology.4.Simulation of winter wheat canopy CO_2 fluxes by a multiplayer two-leaf model.

将生态系统水平与叶片水平的水分利用效率日均值进行比较，前者较后者高，原因可能与研究时对不同尺度采用了不能直接可比的不同的测定方法有关，也可能与涡度相关技术对能量通量的低估有关。4。

We analyzed and discussed the characteristics of cycle of carbon and water,and after having obtained important physiological parameters based on field experiment,a process-based, multilayer two-leaf model which calculates energy and material cycle separately for sunlit and shaded leaves was developed,then characteristic of CO_2 fluxes above the canopy was simulated.The main results are as follows:1.Characteristics of carbon and water cycle in the relationship of leaf photosynthesis -stomatal conductance-transpiration.

本研究以冬小麦为研究对象，利用LI-6400R光合—蒸腾测量系统、LI-6400-09土壤呼吸室和禹城生态试验站涡度相关系统等高精度仪器设备，对2007年和2008年小麦拔节至乳熟期间涉及碳、水循环过程的叶片光合—蒸腾作用、土壤呼吸作用及相关农田气象要素和植被特征进行了野外试验测定和分析，在试验观测基础上提取了重要生理参数，建立了基于过程的农田与大气间物质输送和能量交换的多层—双叶模型，并对2008年试验期间冠层上方碳通量特征进行了模拟，试验分析和模拟的主要结论如下：1。
