Title: Biomass production of different managed meadows in Tibetan Region of Northwest Yunnan Province.
Abstract: In this paper,the plant species diversity and biomass production of different managed meadows in the Tibetan Region of Northwest Yunnan Province were investigated by plot methods.The results showed that in cultivated grassland,forage grassland and grazing pasture,the number of plant species was 49,24 and 12,aboveground biomass was 169.2±69.5,228.0±48.3 and 100.2±35.6 g·m~(-2),underground biomass was 767.7±264.2,1593.5±553.0 and 2593.6±894.3 g·m~(-2),and the ratio of aboveground biomass to belowground biomass was 1∶4.5,1∶7.0,and 1∶25.9,respectively,suggesting that grazing pasture was characterized by less plant species and more underground biomass production,while forage grassland was beneficial to the maintain of high species diversity and high and stable biomass production,being worthy for promoting the grassland restoration in the studied area.
