Abstract
Under the background of global warming, extreme high temperature weather frequently occurs, and the impact of high temperature heat damage on rice becomes more prominent. This study will discuss the impact mechanism of high temperature heat damage on rice, the research method of spatio-temporal distribution characteristics of high temperature heat damage in rice, and the research status of space-time distribution of high temperature heat damage in rice, using the trend coefficient method, Morlet wavelet analysis method, attenuation method. And other methods, combined with the research status at home and abroad, in order to provide a scientific basis for the steady increase of rice production in future agricultural production.
