| 摘 要： | 本文通过田间系统采样，运用地质统计学原理探讨了株高、茎粗两生育指标的空间结构性，并建立了东西、南北、东北、西北四个方向的变差函数模型。结果显示两变量具有较明显的区域化变量特征和较好的空间结构性。且变差函数模型为带状异向性。运用模型迭加的方法建立了所研究变量的带状各向异性套合结构模型。

| Abstract: | Based on field sampling of sunflower height and stem diameter and using the theory of geo-statistics, the spatial structure of the growing indexes was discussed and the semi-variogram models of that were established. The results showed that the two growing indexes have the good spatial structure. The results also showed that the semi-variogram models are ribbon heterogeneous, and the nested theory spherical models were established. |
