A simulation study on CO_2 assimilation and crop growth in agroforest ecosystems in the East China Plain

摘要

The agroforest ecosystems in the East China Plain were classified into two types with 5 different community structures. The CO_2 assimilation capacity of crops in each agroforest system was simulated by the production ecological model SUCROS and that of trees was calculated on the basis of the investigated data of photosynthetic rate of tree leaves, the leaf area index of tree crown, the effective sun shine hours and the correspondent forest coverage in each agroforest ecosystem.
