摘要：

An experiment was conducted to study the effects of climatic factors on tree ring growth of Larix principis-rupprechtii,Betula platyphylla,Tilia spp.and Quercus liaotungensis in Liupanshan region in terms of tree ring index,correlation function and response surface function by stem analysis.Results showed that these tree species exhibited different growth trends and had high sensitivity to environmental factors.Rainfall and temperature in growth season were two major factors influencing tree growth.Growth increment was positively correlated with rainfall.High temperature might support rapid diameter growth,but high temperature with low rainfall would limit tree growth.The effects of temperature and rainfall on tree growth might be interpreted by their restriction on soil water content under suitable conditions of temperature.
