应用灰色系统理论中的关联分析方法 ,分析并指出了影响欧洲落叶松 (Larixdecidua)、美洲落叶松 (Larixlaricina)生长的气象因子大小顺序依次为 :40cm地温、降水量、相对湿度、最低气温、2 0cm地温、水气压、15cm地温、最低地面温度、10cm地温、5cm地温、最高气温、最低本地气压、平均本地气压、平均地面温度、最高本地气压、风速、最高地面温度、蒸发量、平均气温 ;绘制了欧洲落叶松、美洲落叶松树高、地径生长过程曲线 ,初步确定了生长最快的时期 ,为树木的引种驯化提供了理论依据 .
Based on the gray system theory, the relationship between meteorological factors influencing the growth of Larixdecidua and Larixlaricina was analyzed as follows: 40cm temperature, precipitation, relative humidity, minimum temperature, 2 0cm ground temperature, water pressure, 15cm ground temperature, the lowest ground temperature, 10cm ground temperature, 5cm ground temperature, the highest temperature, the lowest local pressure, the average local pressure, the average ground temperature, the highest local pressure, wind speed, the highest ground temperature, evaporation, average temperature; The larch and American larch tree height and diameter growth curves were plotted, and the fastest growing period was initially determined, which provided the theoretical basis for the introduction and domestication of trees.
