Response Analysis Between Climate Factors and the Density of Wood Growth of Picea Crassifolia
摘要
Abstract
The Picea crassifolia naturalized in the middle segment of Qilian Mountains are chosen for research in this paper. With the basic theories and methods of chronology, the responses of the density of wood growth to climate environmental conditions are analyzed using simple correlation. The results indicate that there are significant negative correlations between the density of early wood and precipitation research in May, and the relative coefficient is -0. 623. And there are significant positive correlations between the density of early wood and temperature research in June, and that the relative coefficient is 0.627. All correlations can be explained rationally from the physiology of tree growth. The explanation is in consistent with the law of nature that the tree growth is affected by climate environmental conditions. The calculated results from the correlation functions indicate that the response features of early wood density of Picea crassifolia tree-rings in Qilian Mountains to climate changes are significantly superior to the latewood density and the latewood maximum density.关键词
