西藏东南部地区农作物霉变气象指数研究

Study on meteorological index of crop mildew in southeastern Tibet area

霉变灾害是西藏东南部主要的农业灾害之一。文章分析了西藏东南部特殊的气象条件(气温、相对湿度、水汽压)与农作物发生霉变的特征关系,设计出霉变函数的计算公式和霉变指数查算表,研制霉变指数预测模型并做出预报。结果显示,霉变指数Mildew index的发布能在一定程度上减轻因气象条件致农作物霉变所带来的损失。

Crop mildew is one of the major agricultural disasters in southeastern Tibet.The relationship between crop mildew characteristics and the special meteorological conditions(temperature,relative humidity,water vapor pressure)in southeastern Tibet was analyzed and the a statistical model,mildew index checklist and mildew index prediction model were developed with making forecasts.The results showed that the release of the mildew index can alleviate to some extent the loss caused by the mildew due to meteorological conditions.
