| 摘 要： | 使用地学统计学的方法,对小麦红吸浆虫在较大空间尺度上的分布格局进行分析,建立半变异函数模型,发现其最佳拟合模型为线性有基台模型,模型的空间依赖范围为42.236 8 km,其自相关性和结构特征引起的种群变异为82.62%,说明模型具有较强的空间相关性。由试验结果推断,在小麦红吸浆虫大面积普查中抽样间距应该小于42 km。 |

| Abstract: | Geostatistical method was used to analyze spatial pattern in large scale for the orange wheat midge Sitodiplosis mosellana.The semivariogram curve model was established.The results showed that line-model as the best model revealed the correlation distance was 42.2368km,and orphological variations induced by autocorrelation and structure characteristics was 82.62%,indicating strong spatial correlation in the model.The result suggested that the sampling distance should be less than 42km in the large scale investigation for wheat midge. |
| Keywords: | Wheat midge Large scale Geostatistic analysis Semivariogram |
