冬小麦叶面积指数的空间结构性分析

Spatial structure of the LAI of winter wheat

通过对冬小麦抽穗期的生理性状指标——叶面积指数(LA I)的采样分析,探讨LA I的空间结构性,并建立变差函数模型。结果表明:该变量具有明显的区域化变量特征和较好的空间结构性,可用区域化变量理论进行分析研究。该模型的建立弥补了单纯采用经典概率统计法对作物生理性状进行分析的不足。

By the study of the physiological character of winter wheat-LAI at heading period, this paper discussed the spatial structure of the LAI, and estabilished its semi-sphere model. The results showed that LAI had good regionalized variable characteristic and spatial structure. In the practice, the establishment of the model could offset the shortage of rising classical statistics to study the physiological character of plant.
