摘要
高温热害是三峡库区水稻的主要气象灾害之一,从水稻遭遇高温热害的生物学角度出发,筛选影响气象的主要因子(日最高气温、日平均气温、空气相对湿度等),建立水稻高温热害累积危害指数,结合天气预报,在动态监测水稻高温热害危害的同时,发布水稻的高温热害累积危害指数预警,对水稻防御高温热害有一定的指导意义。
Heat injury is one of the main meteorological disasters for rice in the Three Gorges Reservoir Area.Based on the physiological studies,meteorological factors（daily maximum temperature（℃）,daily mean temperature（℃）and relative humidity） were screened to develop the rice heat injury accumulating damage index.Combined with weather forecast,the index was used to dynamically monitor the rice heat-induced damage and present the early warning for cumulative high Temperature-Induced damage to rice,which was a guide to defend the rice against heat injury to some extent
