摘 要：
为研究大垫尖翅蝗的空间结构,探索其预测预报方法。运用地统计学中的半变差函数和Kriging插值法对山东省大垫尖翅蝗种群的空间结构进行分析和模拟。结果表明:大尺度下大垫尖翅蝗种群的空间结构均为聚集型,不同方向呈各向异性;全方向及0、45、90、135℃方向的最小聚集范围分别为426.73、320.24、447.55、353.65、85.44 km;空间分布模拟图反映了大垫尖翅蝗在山东的具体分布情况,鲁北滨海地区的发生明显重于其他地区。

摘 要：
Epacromius coerulipes was main species of grasshoppers.Geostatistical Semi-variogram and the Kriging interpolation method were used by author to study spatial distribitopm and explore forecasting methods.The results showed that this population distributed in a clump pattern in large-scale.Different directions had different spatial structures,with the minimum clump range of 426.73,320.24,447.55,353.65,85.44 km respectively in the omnidirectional and 0,45,90,135℃.The simulation distribution maps of Epacromius coerulipes,which was interpolated by Ordinary Kriging,showed that the density of Epacromius coerulipes populations in north near sea of Shandong Province were higher than that in others.
