依据桉树青枯病发病流行的系统数据和相应的多种气象要素、土壤含水量和土壤含青枯病菌数量等资料，运用灰色系统理论和多元回归分析方法，分别建立了雷州林业局桉树青枯病的灰色系统预报模型和多元回归预测模型。经检验和验证，证明这两类模型均有很高的可信度。在掌握一定资料基础上，可应用这些模型对桉树青枯病发生流行作出中短期测报。
Based on the systematic data of eucalyptus bacterial wilt incidence and its corresponding meteorological elements, soil moisture content and the number of soil bacterial wilt, using the gray system theory and multiple regression analysis methods, Sick Gray System Forecasting Model and Multiple Regression Forecasting Model. After verification and verification, it is proved that both models have high credibility. Based on a certain amount of information, these models can be used to make short-term and medium-term measurements of the prevalence of bacterial wilt in Eucalyptus.
