英文摘要	Global climate change has led to the nonlinear response of the radial growth of trees to climate change at high altitudes and high latitudes in the northern hemisphere, and the responses of different tree species on climate change due to differences in physiological and ecological adaptations are also significantly different. Therefore, we analyzed the response stability and growth trends and the sustainability of two dominant tree species Qinghai spruce (Picea crassifolia) and Chinese pine (Chinese pine) to climate change on the southern edge of the Tengger Desert. The main conclusions were as follows: 1) water stress was the main controlling factor of the two tree species by analyzing the correlations between the radial growth of two tree species and climate factors. 2) Qinghai spruce had a stable response to Standardized Precipitation Evapotranspiration Index (SPEI) in September of the previous year, and the unstable responses to the minimum temperatures in September, December of the previous year and May of the current year, as well as SPEI in June and July of the previous year and June of the current year; Chinese pine had the stable responses to SPEI in September and May of the previous year, and the unstable responses to the minimum temperatures in September, and December of the previous year and May and September of the current year, as well as SPEI in June of the previous year and March of the current year based on the comparing the response variations before and after the abrupt temperature changes and moving correlation function. 3) The basal area increment (BAI) of Qinghai spruce showed a significant downward trend, and that of Chinese pine showed a significant upward trend, which indicated the Qinghai spruce with shade tolerant and shallow-roots was more severely restricted by climate warming and water stress. Therefore, we must pay more attention to the shade-tolerant and shallow-roots forest ecosystem and strengthen management and protection. (C) 2020 The Author(s). Published by Elsevier B.V.
