利用MODIS数据反演气温监测夏季高温热害

摘要

[Objective] This study was to monitor the hot damage of high temperature on rice in summer by using MODIS data to estimate air temperature. [Method] A new statistical algorithm was introduced for daytime air temperature (Ta) retrievals over east China by using the Moderate Resolution Imaging Spectroradiometer ( MODIS) data, and the high temperature monitoring for rice in south China in 2007 summer was used to demonstrate. [Result] High temperature plays a key role in rice production during rice heading stage in summer in southern China. Using MODIS data to monitor the hot damage of high temperature is a feasible way to relieve agricultural disasters. [ Conclusion ] The result of this study provides a method to monitor hot damage of high temperature tn rice in summer of China.%[目的]研究利用MODIS数据反演气温来监测夏季水稻高温热害.[方法]介绍了一种新的反演我国东部地区白天气温的统计算法,并给出了一个监测2007年我国东部夏季水稻高温热害的例子.[结果]夏季在我国南部水稻的抽穗期期间,高温对水稻的产量起着关键性的影响.利用MODIS数据监测高温热害是减轻农业灾害的一个可行办法.[结论]该研究结果为我国夏季水稻高温热害的监测提供了方法.
