运用典型相关分析方法对北京地区6郊区县的侧柏生长量与气象因子进行分析,结果表明:侧柏是对气象因子反应敏感的树种,气象因子间是相互影响、相互制约、共同起作用的。影响侧柏胸径生长量的重要气象因子是年平均气温和上年3—5月份平均气温;影响侧柏树高生长量的重要气象因子是年降水量和上年6—8月份平均降水;影响侧柏材积生长量的重要气象因子是年降水量和上年12月—当年1月平均气温。由此可以综合得出对北京地区侧柏生长量影响较大的气象因子是气温和降水量。
The results showed that: Platycladus orientalis is a tree species that is sensitive to meteorological factors, and the meteorological factors interact with each other and interact with each other and play a joint role . The important meteorological factors influencing DBH growth are the annual mean temperature and the average temperature in March-May of last year. The important meteorological factors influencing the growth of cypress cypress height are the annual precipitation and the mean precipitation in June-August last year; The important meteorological factors of the volume of cypress volume are the annual precipitation and the average temperature in January last year from December to January. It can be concluded that the greater impact on the growth of Oriental arborvitae in Beijing meteorological factors are temperature and precipitation.
