欧洲落叶松,美洲落叶松生长与气象因子关系的研究

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（Ｌａｒｉｘ ｄｅｃｉｄｕａ）、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、２０ｃｍ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

Relationships between Growth of Larix laricina and Larix decidua and Meteorological Factors

Using the method of joint analysis of the grey system theory,meteorological factors influencing growth of Larix laricina and Larix decidua are descending order of importance,40?cm underground temperature,precipitation,relative humidity,the lowest temperature,20?cm underground temperature,water barometric,15?cm underground temperature,the lowest temperature of ground,10?cm underground temperature,5?cm underground temperature,the highest temperature,the lowest contemporary barometric,the average contemporary barometric,the average temperature of ground,the highest contemporatry barometric,wind speed,the highest temperature of ground,annual evaporation capacity,the average temperature of a day,tree height and diameter growth curves of Larix laricina and Larix decidua were drawn.The fast speed growth period can provide basis for the introduction and domestication,and the calculating models of GM(0, N ) were made.
