Abstract:

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.
