东北红豆杉生长与气象因子关系的初步调查

A Preliminary Investigation on the Relations between Growth of Taxus cuspidata and Meteorological Factors

应用灰色系统理论中的关联分析方法，分析并指出了影响东北红豆杉生长的气象因子大小顺序依次为：本地气压、相对湿度、地面最高温、日最高温、风速、降水量、水汽压、５ｃｍ地温、１５ｃｍ地温、日最低气温、气温、地面均温、蒸发量、地面最低温、４０ｃｍ地温；绘制了东北红豆杉树高、地径生长量曲线，确定出相应生长量的最佳物候期，为东北红豆杉的经营利用提供了良好的理论；利用关联分析得出的影响东北红豆杉生长的主要气象因子，建立了Ｇ（０，Ｎ）预测模型．

Using the method of joint-anlysis of the Grey System theory, this paper points that meteorologicalfactors infuencing growth of Taxus cuspidata are descending order of importance, contemporary barometric,relative humidity,the highest temperature of ground ,the highest temperature of a day, wind speed, precipita-tion,water barometric,the temperature of 5cm deepth under soil,the temperature of the 15cm deepth undersoil,the lowest temperature of a day ,the average temperature of a day, the average temperature of ground, an-nual evaporation capacity, the lowest temperature of ground,the temperature of the 40cm deepth under soil,the temperature of the dew point,drawing curves of the growth of Taxus cuspidata,definiting the best growth period and offering a good theory for the management ,and the calculating models of G(0,N)that in- fluenced growth of Taxus cuspidata are made.
