| 摘 要： | 运用灰色关联分析理论,对橡胶2010年每月产量及气象因子关联度进行分析。结果表明:影响橡胶产胶量的9个气象因子按照关联度由大到小依次排列为日照最高气温平均湿度平均气温最小湿度蒸发量风速最低气温雨量;进一步的逐步回归分析表明,胶量与雨量呈显著的负相关,与灰色关联性分析的结果一致。

The Gray Relevancy Analysis and the Stepwise Regression Analysis Between Latex Yield and Meteorological Factors |
| |
| Abstract: | By the use of gray relevancy analysis theory, the correlation between Latex yield and meteorological factors of each month was analyzed in one year. The result showed that the influential degree of each meteorological factor on latex yield was ranked in a descending order of the sunlight hours>maximum air temperature>mean daily humidity>average temperature>minimum humidity>evaporation capacity>wind speed>minimum air temperature>precipitation. The stepwise regression analysis result was in accordance with the gray relevancy analysis result that the latex yield and the precipitation are negatively correlated. |
