Abstract: The researcher establishes the planter industry structure adjustment space assistance decision system mainly is for enabling the county territory planter industry economic efficiency to achieve the maximization, causing the county territory crops planter structure optimization, providing policy-making for the policy-maker the basis; In the decision system research, the researcher establishes the auxiliary policy-making model according to the characteristic of the studied region, uses in GIS MapObjects to control to inlay the type integration with the assistance decision-making model in the method, applies VB programming language; The policy-maker may carry on the dynamic inquiry in the planter industry structure adjustment space decision system to the crops planter data, which is allowed to be direct-viewing dynamically demonstrates in the corresponding map position. Under the backstage database support, the policy-maker may calculate every year each villages and towns each kind of crops the being suitable parameter. Through the decision system the policy-maker may automatically participation the crops being suitable parameter input model in the computation crops the sown area, the policy-maker may act according to in the different situation choice decision system the different model to carry on the computation crops planter the adjustment data. The policy-maker may carry on the comparison according to the old times crops sown area and the computation obtained sown area, obtain sown area which the crops needed to adjust. The system may act according to adjusts the crops sown area to carry on the benefit analysis, the profit analysis, the production graph, The system can be direct-viewing dynamically provides the support for the decision-making. The decision system that develops carries on the example confirmation taking the Hebei Zhengding County as the example, finally indicated that this system design is reasonable and feasible and provide the policy-making support for the county territory planter industry structure adjustment. The system has the certain practice value and the significance.
