Larix gmelinii var. principis-rupprechtii, widely distributed across Northern China, possesses substantial ecological value for soil and water conservation, water source preservation, carbon sequestration and oxygen release. In this study, we collected tree cores of Larix gmelinii var. principis-rupprechtii plantations from 11 sites in 7 provinces. Chronologies of earlywood, latewood, and total ring were established to assess the responsiveness of radial growth to climatic factors, and discuss the differences between the responsiveness in different regions under the background of climate warming. The results showed that the expressed population signal (EPS) of the tree-ring samples of Larix gmelinii var. principis-rupprechtii at all 11 sites was greater than 0.85, and the mean sensitivity (MS) was above 0.15, indicating that the radial growth at each site were greatly influenced by climate change and contained a considerable amount of climate information. Temperature and precipitation from December of the previous year to March of the current year promoted the growth of Larix gmelinii var. principis-rupprechtii, while high temperatures and droughts in summer typically restricted growth at most sites. Research sites across various geographical locations exhibited varying outcomes. Water condition was the predominant limiting factor affecting the growth of Larix gmelinii var. principis-rupprechtii at sites in the central and northern regions. In the northwestern sites, the promoting effect of temperature increase on the radial growth was more obvious than that of precipitation. BY was simultaneously restricted by both temperature and precipitation. After the warming abrupt change, the correlation between temperature and the radial growth changed from a positive correlation to a negative correlation, and the promoting effect of precipitation on the growth of Larix gmelinii var. principis-rupprechtii was gradually manifested. The growth differences under different levels of climatic factors fluctuate slightly. When the maximum temperature was under 10 ℃, the increase in average temperature and maximum temperature had a promoting effect on the growth of Larix gmelinii var. principis-rupprechtii. Sufficient water conditions can lead to a small increase in the radial growth. When 0.5Larix gmelinii var. principis-rupprechtii. When average temperature was under 4 ℃, the response of earlywood to the increase in average temperature was more obvious than that of latewood; at other levels, the responses of both to each climatic factor were basically the same.
