摘要

The photosynthetic parameters of Pinus tabulaeformis plantation were measured after covering forest land by palm mat for two growing seasons. The result indicates the daily maximum photosynthetic rate and the photosynthetic rate in the photosynthesis saturated point increased by 30% and 10.6%~44.3% respectively compared with the CK, the transpiration rate and stomatal conductance increased to some extent, while the light compensation point and the water use efficiency between the treatment and CK were no significant differences.
