Radial Growth–Climate Relationship Varies with Spatial Distribution of Schima superba Stands in Southeast China’s Subtropical Forests

To understand the impact of climate change on tree radial growth in Southeast China’s subtropical evergreen broadleaved forest, comparative research growth–climate associations Schima superba was conducted. This dominant species examined at both its southern and northern distribution margins through dendroclimatology. The results showed that S. stands a high elevation margin were positively correlated with springtime temperatures, mostly April (e.g., mean temperature: r = 0.630, p < 0.05) May maximum 0.335, 0.05), respectively. Meanwhile, temperature late rainy season had significant negative effect margin, including high-elevation previous current September: −0.437 −0.383, low-elevation August October: −0.577 −0.348, 0.05). It shown key climatic factor affecting superba, response to obvious spatial differences. findings indicate warm environments will be negatively impacted by future warming. On contrary, growing relatively cold may benefit from warmer spring. enhance understanding responses forests China.
