The photo—·physiological characteristics of Achnatherum splendens both in the enclosure an d the grazing pasture were moni-toted in Anxi.Th e results showed that the diference was significant between them.Th e air temperature and leaf temperature were rela.tively lower and the relative humidity Was higher in the enclosure compared with those in the grazing grassland.These indicated that the environment of grass growth Was greatly improved by enclosure means.At the same time,there Was higher photosynthetic rate of Ach-hat.rum splendens in the enclosured grassland.This Was beneficial to growth of grass and accumulation of dry matter.
