【Abstract】 With the object oriented software development method, a crop yield forecast system run under the Microsoft windows operation system was successfully developed, by using VB and MO as development tools on the basis of the principle that crop yield equals trend yield plus meteorological yield. This system integrated the database technique with COM GIS technique and realized close connection among modules.更多还原
