日本柳杉生长对气候的响应

Radial Growth Responses of Cryptomeria japonica to the Climate

对建立的日本柳杉的差值年表与气象数据进行的相关性分析结果表明:日本柳杉的生长与上年10、11月的温度,与上年12月、当年1月的降水量正相关;与当年3月的降水量、8月的温度负相关。这既是日本柳杉海拔分布的重要因子,也是影响林分生物生产力和碳循环的重要因素。

Coefficents of residual chronology of Cryptomeria japonica and climate data showed that the radial growth of Cryptorneria japonica was positively positively correlated to the temperature of the prior October and November, and the precipitation of the prior December and the crrent Janary, but negatively correlated to the precipitation in March and the temperature in August of the current year. They are not only decisive factors of altitudinal distribution of Cryptomeria japonica, but also important conditions of biomass accumulation and carbon cycle.
