摘要： Frequent high temperature has become an important agricultural meteorological disaster to the middle-season rice yield and quality in southwest China where has hot rainy season and obviously three-dimensional climate. This paper analyses the meteorological data of more than 70 weather stations in southwest China from 1960 to 2010 using binomial nine moving average method, Morlet wavelet analysis and inverse distance weighted interpolation method, and summarizes the spatial-temporal variation rules of the high temperature damage of middle-season rice from heading and flowering time to grain filling and milky ripe time. The results grasped the macroscopic laws of high temperature damage for rice occurred in southwest, which has the certain reference function for the guidance of high temperature damage prevention for middle-season rice in southwest china, optimizing the layout of rice production.
