摘要
根据区划理论 ,应用数学方法和计算机技术 ,将福建省竹蝗灾区区划为 3个区和 3个危险程度等级 ,并建立 I、II级危险程度等级的发生面积预测预报数学模型。经检验 ,模型精度较高 ,拟合效果好 ,可在生产上推广应用。
Ceracris kiangsu Tsai is the main pest of bamboo forest in Fujian Province. The plague division of Ceracris kiangsu was studied by division theory and mathematical method to provide the scientific basis for the pest management and forecasting. The result indicated that the plague division was divided into three zoons and three dangerous grades. The forecasting mathematical models of damage area built respectively to various dangerous grades are high precise and practical for the pest control.
