Abstract: Correlation analysis of aboveground biomass, community diversity and soil nutrient characteristics on Alpine meadow in Henan County under different reseed year were studied. The results showed that reseeding Gramineous plants on Alpine meadow can effectively increase the grassland biomass on the grassland, improve the community species and richness index. While soil moisture becomes the leading factor to limit plant growth in this region, soil total nitrogen, total phosphorus content is also limit factor. The research results can provide reference for improving degraded alpine meadow grassland and rational utilization.
Key words: Aboveground biomass; Community diversity; Soil nutrients; Correlation analysis
