陆面生态过程的一维数值模拟

One dimensional Numerical Simulation of the Land Surface Ecological Processes

建立了一个研究大气、植被、土壤相互作用的传播模式。模式是由多层大气模式、多层土壤模式和植被模式通过界面上能量、水汽传输平衡方程耦合而成。对植被和土壤的不同性质，进行了一系列的数值试验。结果表明，不同的植被覆盖以及降水等因子会对大气、植被、地表界面上能量、水汽传输以及热状态产生显著的影响。此模式还可以耦合进中尺度模式用以研究非均匀区域陆面过程和大气的相互作用。

A transfer model is established, which can be used to study the interaction between atmosphere, vegetation and soil. The model is composed of multilayer atmosphere, multilayer soil model and vegetation model which are coupled by balance equation describing the energy and moisture transfer at the interface. A series of tests are preformed to assess the sensitivity of the scheme to the inclusion of variable soil and vegetation characteristics. The results show different vegetation cover, different soil and vegetation types and precipitation exert great influence on energy, water transfer between soil, vegetation and atmosphere. The model developed can be coupled in mesoscale models to study the interaction between land surface processes and the atmosphere in inhomogeneous regions.
