Response to Climate Change about Radial Growth of Larix gmelinii Main Forest Types in Daxing’anling Mountains

Abstract:

Tree-ring width chronologies were developed for Larix gmelini of main forest types in Daxinganling mountains, and by correlation analysis and response function analysis illustrate difference empact of main climate factors on radial growth of Larix gmelini. The result shows ring-width chronologies of Larix gmelini we have made containing a lot of climate informations. In the correlation analysis, impact of temparature on Larix gmelinii is higher than presipitation, average month temperature is negatively correlated with ring-width growth and correlation efficient is higher, especially February temperature is significantly negatively correlated with radial growth of Larix gmelini three forest types. Response functions analysis indicating that Bryaceae—Larix gmelinii forest is more sensitive to climate and the response is complex. The sensitivity are: Bryaceae—Larix gmelinii forest > Ledum palustre—Larix gmelinii forest > Bryaceae—Larix gmelinii forest.
