摘要
为了探究油松(Pinus tabulaeformis)幼树高生长与气候因子之间的关系,找出决定和影响油松生长的气候因子及其在各主要时间段的气候因子。以河北遵化地区15年生油松幼树为对象,通过连续9 a对油松幼树高生长的调查,结合收集遵化当地气象站相应的逐月气象资料,利用灰色关联度分析法,对油松高生长量与气候因子进行关联分析。结果表明:温度和降水是影响油松幼树高生长的重要因素;前一年冬季(12月—次年2月)的气温、地温以及前一年夏季(6—8月份)的降水量是影响油松高生长的主导气候因子;当年油松高生长季前期的温度和前一年油松高生长结束期的降水量对油松高生长的影响最大,关联度都达到0.9以上。
The experiment was conducted to explore the relationship between the height growth of Pinus tabulaeformis saplings and climatic factors and find out the climatic factors that determine and affect the growth of P.tabulaeformis and their climatic factors in each main time period.We took 15-year P.tabulaeformis saplings in Zunhua,Hebei Province as the object,and studied the height growth of P.tabulaeformis saplings for nine consecutive years,combined with the monthly meteorological data collected from the local weather station in Zunhua,by using the grey correlation analysis method,correlation analysis of high growth of P.tabulaeformis and climatic factors.The temperature and precipitation are important factors affecting the height growth of P.tabulaeformis saplings.The temperature and ground temperature in the previous winter(December-February)and the precipitation in the previous summer(June-August)were the dominant climatic factors affecting the growth of P.tabulaeformis.The temperature at the early stage of the growing season of Pinus tabulaeformis and the precipitation at the end of the growth period of P.tabulaeformis in the previous year had the greatest impact on the growth,and the correlations were both above 0.9.
