摘要
根据区划理论,应用数学方法和计算机技术,将福建省木麻黄毒蛾灾区区划为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,该模型精度较高,拟合效果好,可在生产上推广应用。
Lymantria xylina Swinhoe is the main pest in Casuarina spp. in Fujian Province. It's plague division was studied to provide scientific basis for the pest management and forecasting with division theory and mathematical method .The plague was divided into three zoons,and three dangerous classes.The mathematical models for the forecast of area were built respectively for various dangerous classes, which are of high precision and practical for the pest control in production.
