In this paper, the tree-ring-width chronologies of Picea schrenkiana and Juniperus jarkendensis in western Kunlun Mountains are developed based on their core samples. Radial growth-climate response and its stability were discussed by analyzing the radial growth characteristics of two coniferous species and their correlation with climate factors. The results show that there was a significant positive correlation between P. schrenkiana and J. jarkendensis chronologies in the study area The interannual change of the chronologies index of two tree-ring-width and basal area increments (BAI) shows a rising trend before the year of abrupt temperature change in 1994, while they show a declining trend after the year of abrupt temperature change. The tree radial growth rate of the J. jarkendensis is higher than that of P. schrenkiana. The results of the correlation between radial growth and climate change showed that the radial growth of P. schrenkiana was significantly negatively correlate with the temperature in the growing season of previous year (May-June and August-October) and the growing season of current year (March-June and October), while the radial growth of J. jarkendensis was significantly negatively correlate with the temperature in October of previous year and the early growing season of current year (April-June). Both of them are significantly positively correlated with the spring precipitation of current year. The results of sliding correlation analysis show that the limiting effect of temperature on the radial growth of the two tree species is enhanced in the growing season of previous year and current year, especially in the early growth season of current year. In addition, the promoting effect of precipitation on tree radial growth in the early growing season is also enhanced. After the possible year of abrupt climate change (1994), the response sensitivity of the two conifer tree species to temperature and precipitation was enhanced, and the response sensitivity of P. schrenkiana to temperature was stronger than that of J. jarkendensis, the sensitivity to precipitation was weaker than that of J. jarkendensis.
