[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。
[Objective] The research aimed to study the use of MODIS data to retrieve the temperature in summer to monitor the thermal damage of summer rice. [Method] A new statistical algorithm for inversion of daytime air temperature in the eastern part of China was introduced. An example was given to monitor the heat damage of paddy in eastern China in summer 2007. [Result] During the heading period of rice in the southern part of China in summer, the high temperature had a crucial effect on the yield of rice. Using MODIS data to monitor high-temperature heat damage is a feasible way to reduce agricultural disasters. [Conclusion] The results of this study provided a method for monitoring summer thermal damage in rice in China.
