一个植物冠层物理传输和生理生长过程的多层模式

通过提出一个多层的植物冠层和土壤的模式，对冠层中辐射、热量、水汽和二氧化碳的传输等过程，光合、呼吸等生理过程以及土壤中水、热传输等过程进行了详细描述，并把物理过程与生理过程联系起来，实现了植被与大气的双向反馈；应用此模式于小麦生长期各主要过程的模拟，给出了与观测值一致的结果

A Multi-Level Canopy Model Including Physical Transfer and Physiological Growth Processes

Based on a feedback mechanism between physiological growth processes of plant and abiotic environment-soil and atmosphere, a multi-level Atmosphere-Vegetation Interaction Model (AVIM) to link physical transfer and physiological growth processes at land surface is proposed Observational data of winter wheat field collected from Yucheng agricultural ecosystem station, North China, March-June 1992, has been used to simulate the wheat growth and surface fluxes with the multi-level AVIM The results show that energy budgets, thermal and moisture states of canopy and soil are well simulated, and the simulated biomass of tissues, leaf area index and CO 2 flux are in agreemeet with the observations
