The results show that there was a negative correlation between average annual rainfall and temperature.The prediction results for future tendency show that the annual average rainfall will still keep downtrend, the annual average temperature will keep rising trend.The trend of change is mainly controlled by the global warming and the large-scale climate variations, and the results indicate that the trend of change is basically consistent with the trend of the Yangtze river basin.
