Abstract:Tree growth-climate relationship is critical for accurately assessing the impact of climate change on forest ecosystems, predicting forest productivity and vegetation dynamics, and revealing tree adaptation strategies to climate change. In the context of global warming, rising temperatures may have an impact on tree growth, thereby changing the productivity or carbon storage in regional forest ecosystems. We investigated the main climatic limiting factors of radial growth of Korean pine (Pinus koraiensis) and Korean spruce (Picea koraiensis) in broad-leaved Korean pine forests in Yichun city, China. We also discussed the similarities and differences of their response to rapid warming (after 1980) by using the growth-climate response function analysis, moving correlation analysis, and other dendroclimatology methods. The results showed that the radial growth of Korean pine was accelerated before 1980, and the upward trend of Korean spruce was weaker than that of Korean pine. However, after 1980, the radial growth trend of Korean pine was significantly decreased, while that of Korean spruce was not. The radial growth of Korean spruce was significantly negatively correlated with the mean temperature in previous September and current June, while the radial growth of Korean pine was significantly positively correlated with the minimum temperatures in previous December and January, April and June of the current year. After rapid warming in 1980, the high temperature significantly increased the growth inhibition of the two species, especially for the Korean pine. The limiting effect of precipitation at the end of growing season (September) on Korean pine and Korean spruce changed from the negative correlation before warming to significant positive correlation after warming. In general, temperature is the main climate factor limiting the radial growth of Korean spruce and Korean, followed by precipitation.The radial growth of Korean pine was more sensitive to climate change than that of Korean spruce. After rapid warming, the change of growth-climate relationship of Korean pine and Korean spruce may be related to the 'Warm-dry Phenomenon' caused by the warming. If climate warming continues or intensifies, the climatic limiting factor of the radial growth of the two species will change from temperature to moisture, and their radial growth will decline, especially for Korean pine.
