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． Based on the gray system theory, the paper analyzes and points out the order of the meteorological factors influencing the growth of Taxus cuspidata: local pressure, relative humidity, the highest temperature on the ground, the highest temperature, wind speed, precipitation, vapor pressure, 5cm Temperature, average temperature, evaporation, the lowest temperature on the ground, 40cm ground temperature; Draw the height and diameter growth curve of the tree of Taxus cuspidata, determine the best phenophase of the corresponding growth, Which provided a good theory for the management and utilization of Taxus chinensis. Based on the main meteorological factors that affect the growth of Taxus chinensis, the prediction model of G (0, N) was established.
