Abstract
The research project on the environmental factors of alpine pastures and its utilization in the Ghunsa Valley located in the Kanchenjunga Area was conducted in 2000-01. The research items related to the environmental factors are: condition of landform and vegetation; biomass of herbaceous plants; and air temperature in the pastures. The following facts are clarified. At first, the herbaceous vegetation is composed by about 40 different dominant species. Secondary, biomass of herbaceous plants in main pastures was 2272g/m2 at flat ground and 380g/m2 at slope(weight in raw) as of the end of August. These values were utilized for evaluation of the productivity of pastures in the whole study area. At the same time, effects of grazing against the biomass were examined by comparison between pre- and post-grazing.
