    摘要:

    以ArcIMS為二次開發(fā)平臺，開發(fā)了基于Java技術和MVC架構的蘋果病蟲害預測預報系統(tǒng)平臺，在建立了20余種蘋果病蟲害預測模型的基礎上，采用動態(tài)數(shù)據(jù)交換技術（DDE）實現(xiàn)了GIS分析功能與病蟲害預測模型的集成；具有空間數(shù)據(jù)和屬性數(shù)據(jù)的分析處理、蘋果病蟲害預測預報、WebGIS信息發(fā)布等功能；可以通過地圖或專題圖、數(shù)據(jù)表格、圖形或文字等多種形式預測預報蘋果病蟲害發(fā)生時間和發(fā)生程度。以蘋果山楂葉螨為例，詳細闡述了系統(tǒng)中徑向基網(wǎng)絡模型的構建，該模型的測試準確率為87.5%，高于BP神經(jīng)網(wǎng)

    Abstract:

    絡的75%。A forecast system of diseases and pests for apple orchards was developed by using MVC structure with Java support based on ArcIMS. The forecast model, which could predicate 20 kinds of the diseases and pests, was integrated with spatial analyses of GIS by dynamic data exchange (DDE). The system can be applied to analyze spatially and temporally, forecast the diseases and pests, and promulgate the information with WebGIS. The forecasting of the regions and infection tendency of diseases and pests can be revealed with several patterns, such as map filled with different colors, topic graph, data table, text, or figure. Additionally, for instance of Tetranychus Viennensis in apple orchards, the predicting model constructed with radial basis function neural network (RBFNN) was purposed in this paper, and the predicting results were compared with those of backpropagation (BP) neural network model. 
