| 摘 要： | 叶面积是树冠特征的重要标志 ,其大小直接影响树木生产力 .通过应用灰色系统理论中的GM( 1 ,1 )模型 ,以乳源木莲叶面积与胸径生长量实测数据为基础 ,结合叶面积静态模型得到一组叶面积时间序列 ,建立了乳源木莲叶面积动态预测模型 ,旨在为研究乳源木莲生理生态过程提供理论依据 .经初步检验 ,该叶面积动态模型效果良好 ,应用范围较广 . |
| 关 键 词： | 乳源木莲 叶面积 灰色系统 动态模型 |

| Abstract: | The area of leaf is the important mark of crown of a tree ,and its size directilly affects the productivity of the trees Based on the data of leaves area and growth of DBH of Manglietia yuyuanensis Law,a time series of leaf area was obtained combining the static model of leaf area Based on the time series of leaf area, the dynamic model of Manglietia yuyuanensis Law leaf area was constructed with gray system theory Testing on the model showed that the dynamic model of Manglietia yuyuanensis Law leaf area has a satisfactary effect in predicting for short and middle term |
| Keywords: | Manglietia yuyuanensis Law leaf area gray systemtheory dynamic model |
