Analysis on Canonical Correlation between the Growth of Platycladus orientalis and Climatic Factors in Beijing

Abstract

Abstract: The relationship between the growth of Platycladus orientalis(GPO)and climatic factors(CF)was analysed by the canonical correlation analysis method in Beijing.The results showed that Platycladus orientalis was a kind of tree which responds sensitively to CF.There were mutual effects among CF,and CF effect GPO together.The annual average temperature and the average temperature from March to May in previous year were the dominant meteorological factors affecting the diameter growth of Platycladus orientalis.The increment of height was affected mainly by the annual precipitation and the average precipitation from June to August in previous year.And the average precipitation and average temperature from December of previous year to January of current year were the important factors influencing the volume growth.It was concluded that the most important CF that affects the GPO were the temperature and the precipitation.

Key words: Platycladus orientalis, climatic factor, canonical correlation, Beijing area
