Abstract

Abstract:

Aims It is not clear if plants respond phenologically to global warming in desert area, and if they do, what is the pattern of the change? We analyzed phenological data observed from 18 tree species for up to 34 years in the Minqin Desert Botanical Garden. Our objectives were to determine the relationships between plant phenology and air temperature change in the Minqin Desert area.

Methods The trend lines for change in temperature and phonology were linear, the correlation between temperature and phenology was expressed by a relationship coefficient and the significance of the relationship coefficient was examined by the t-test.

Important findings The effect of the prior month’s temperature on phenology was less than that of the current month’s temperature, but more than that of the annual mean temperature. The temperature increase in spring was more obvious in the study area than other parts of the region, which was likely the reason that the local spring phenology had a relatively large advance. The change in plant phenology, particularly in the desert, was not only a response to climate change, but also an adaptation to climate change.

Key words: typical desertification area, plant phenology, air temperature, Minqin
