摘  要：
为探讨大气环流指数和地面气象要素对海南省橡胶树白粉病病情指数的影响,利用1962-2009年逐月大气环流指数和逐日地面气象要素资料,根据橡胶树白粉病病情指数等级,结合因子膨化、相关分析和多元回归等方法,筛选影响橡胶树白粉病病情指数的大气环流指数和地面气象要素,构建等级指标,建立预测模型,并对模型进行检验.结果显示:影响橡胶树白粉病病情指数的大气环流指数依次为北半球副高面积指数、北半球副高强度指数、西太平洋副高西伸脊点、北美区极涡面积指数、亚洲区极涡强度指数和印缅槽,显著影响时段为上年7月至当年4月;地面气象要素有平均最高气温、相对湿度、平均气温≥20℃的日数、小雨日数和平均风速,显著影响时段为上年10月至当年1月;基于大气环流指数、地面气象要素、大气环流与地面气象综合因子的橡胶树白粉病病情指数预测模型准确率分别为74.3%~78.8%、74.7%、94.6%~98.3%,表明基于大气环流和地面气象综合因子的模型准确率较高,可作为海南省橡胶树白粉病的中长期预测模型.

摘  要：
In order to research the influences of atmospheric circulation index and surface meteorological elements on the disease index of the rubber tree powdery mildew in Hainan Province, the atmospheric circulation index and surface meteorological elements that affected the disease index of rubber tree powdery mildew were selected, and the indicator and prediction model of the rubber tree powdery mildew disease index in Hainan Province were established with the monthly atmospheric circulation characteristics data and the daily surface meteorological data from 1962 to 2009, based on the rank of the rubber tree powdery mildew disease index, combined with factor puffing, correlation analysis and multiple regression. The results showed that the rank of atmospheric circulation index which affected the disease index of the rubber tree powdery mildew included the northern hemisphere subtropical high area index, the northern hemisphere subtropical high intensity index, the West Pacific subtropical high extension ridge point, the North American polar vortex area index, the Asian polar vortex intensity index and the India-Burma trough. The effect of period was mainly from previous July to current April. The surface meteorological elements which affected the disease index of the rubber tree powdery mildew were the average maximum temperature, the relative humidity, the days of average temperature above 20℃,the days of light rain, and the average wind speed. The effect of period was mainly from previous October to current January. Based on the atmospheric circulation index, the surface meteorological elements,the comprehensive factors of atmospheric circulation and surface meteorology, the accuracy rate of prediction models predicting the disease index of rubber tree powdery mildew were 74.3%-78.8%, 74.7%,94.6%-98.3%. Meanwhile, based on the comprehensive factors of atmospheric circulation and surface meteorology, the prediction model of rubber tree powdery mildew disease index had high accuracy, and it could be used for medium and long term predicting local rubber tree powdery mildew occurrence.
