摘要
毛竹枯梢病是国内重要检疫对象。对该病进行灾区区划具有重要的现实意义。根据区划理论,应用现代数学方法和计算机技术,将福建省毛竹枯梢病灾区分为重灾区、轻灾区和基本无灾区3个区及Ⅰ级、Ⅱ级、Ⅲ级3个危险程度等级,并按照不同的危险程度等级区域,分别建立了发生面积预测预报模型。该模型经检验,具有较高的精度,可以推广应用。
Ceratosphaeria phyllostachydis is an important plague under quarantine in China,and it is significant and practical to classify its plague areas.With the application of classification theores,modern mathematic methods and computer techniques,the areas of Ceratosphearia phyllostachydis in Fujian can be classified as serious,light and basically none-plague areas and three dangerous degrees including class Ⅰ,class Ⅱ and class Ⅲ.Model of forecasting plague areas is established according to different classes.The model is tested to be precise and can be popularized.[Ch,2 tab.9 ref.]
