甜菜锈病在中国的可能发生区预测

Evaluation on the Potential Establishment of Beet Rust in China with Plant Quara ntine Information System

利用计算机植物检疫咨询系统分析了甜菜锈病发生危害区的气候条件 ,确定了甜菜锈病发生流行的生物气候指标 ;并根据该生物气候指标及中国各地区与甜菜锈病的原发生地 (法国 )的生物气候相似程度 。

To analyze the potential establishment of exot ic pests is one main fun ction of the plant quarantine computer information system. First, the bioclimati c indexes of the beet rust development epidemic were determined by analyzing the climate environments of the beet rust development and epidemic. Then, the viabl e regions were assessed by using the bioclimatic indexes and the bioclimatic ana logous distance between the original place(France)of beet rust and various are as in China with the plant quarantine computer information system.
