Abstract

Taking moderate desertification of alpine meadow as a study object, considering the impact of different types of fertilization on grassland community species composition, diversity patterns, community structure and productivity, the paper aims to seek the best fertilization levels of different types of fertilizers. The results showed that: 1) in different fertilization treatments (except for three levels of potash handling), the main advantage of the important species differ significantly between the values. 2) J, D, Ma, C and H' species diversity index of the three levels in the manure handling treatment and three levels of nitrogen fertilizer process increased with fertilizer increases, and three levels of phosphate fertilizer and three levels of N-P-K fertilizer treatment, the trends were convex. 3) Average height of vegetation and four functional groups of organic fertilizer in aboveground biomass of three levels of processing and handling are three levels of nitrogen fertilizer with the increase of the three levels of fertilizer treatment and the three levels of N-P-K fertilizer treatment significantly increased the amount of fertilizer which are convex with the trends, the differences between both reached a significant level. 4) Three levels of potash fertilizer treatment on the species composition, diversity change, vegetation height and aboveground biomass have no significant impact. Taking into account the reasonality and the stability of grassland productivity and community structure, O3, P2, N3, and N-P-K2 are the best fertilization level for the desertified alpine meadow.

Key words： fertilizer application level; Maqu; desertification of alpine meadow; plant characteristics; productivity
