Abstract:
Based on the meteorological data, the temporal and spatial distribution, the major diseases and insect pests data collected from Cornus officinalis producing areas (including 200 stations over China), we established a model for forecasting diseases and insect pests in Cornus officinalis by using IDW(inverse distance weight)method.The results showed thatthis model has isvisual character. Meanwhile this model can be used for predicting the occurrence and distribution in diseases and insect pestsof Cornus officinalis.
