Abstract

Abstract: Nitrogen deposition and changes in precipitation patterns are profoundly affecting the structure, function and key processes of grassland ecosystems. Based on the global change experimental platform of the Urat Desert-grassland Station, this paper studied the effects of nitrogen addition (N) and increasing or decreasing rain (+50%, -50%) and their interaction on photosynthetic rate and vegetation characteristics of desert steppe plant communities. The relationship between photosynthetic rate and vegetation characteristics of plant communities in desert grassland was analyzed. The results showed that:(1) Short term nitrogen addition had no significant effect on photosynthetic rate and vegetation characteristics of desert grassland plant communities (P > 0.05); (2) Precipitation pattern change significantly affected photosynthetic rate of desert plant community (P < 0.05), rain reduction 50% significantly reduced the photosynthetic rate and dominant plant height of desert steppe plant community (P < 0.05), while 50% precipitation increase did not change the photosynthetic rate and characteristics of the community, the photosynthetic rate of the community could be well explained by the soil water under the change of precipitation; (3) The interaction effect of nitrogen addition and precipitation increase was significantly improved. The photosynthetic rate of the community and the height of the dominant plant (P < 0.05), while reducing the precipitation and nitrogen addition had no significant effect; (4) The coverage of the plant community in the desert steppe, the coverage of the dominant species, and the average height of the dominant species showed an exponential increase relationship with the photosynthetic rate of the community, with an explanatory rate of 40%-58%. The occurrence of drought can greatly inhibit the photosynthetic rate of plant communities in desert steppe, while nitrogen deposition relies on the increase of precipitation to significantly increase the photosynthetic rate of the community. The photosynthetic rate of plant communities in desert steppe is closely related to the plant growth characteristics under water and fertilizer treatment.

Key words: desert grassland, plant community, community photosynthetic rate, nitrogen deposition, precipitation pattern change
