| 摘 要： | 为研究干旱半干旱地区气候因子对树木生长的影响,以六盘山地区4个主要树种(落叶松、白桦、椴树、辽东栎)为研究对象,在树干解析的基础上,依据年轮指数,采用相关函数和响应面函数分析了树木生长与气候因子的关系.结果表明:六盘山地区不同树木的生长趋势存在差异,对环境因子的敏感度较高;树木生长受制于生长期的2个气候因子--温度和降水.其中降水和树木生长呈正相关,随着降水量的增加,树木生长量也随之增加;一定程度的高温会促进树木生长,但高温少雨会抑制树木生长.在温度适宜树木生长的条件下,温度和降水这2个气候因子,在某种程度上可以认为是通过对土壤含水量的制约,从而影响树木的生长速度. |

| Abstract: | 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 i... |
| Keywords: | Stem analysis Tree ring index Correlation function Response surface function |
