Abstract: In order to improve Nanning's climate response capacity of social and economic development in the context of global climate change and to understand the characteristics of its climate change over the past 30 years, this paper researches and studies the climate change in Nanning in the past 30 years on the basis of Nanning's average temperature, precipitation and sunshine hours from 1991 to 2020, using linear regression method, moving average method and accumulative anomaly method. The results show: in the past 30 years, the average temperature of Nanning has shown a decreasing trend, representing a decrease of 0.007 1 ℃/a, and the average temperature of seasons except for spring has demonstrated a decreasing trend; the precipitation has shown a decreasing trend, representing a decrease of 0.887 mm/a, and the average precipitation of the seasons except for summer has demonstrated an increasing trend; the sunshine hours have shown an increasing trend, representing an increase of 6.300 1 h/a, and the average precipitation of seasons except for autumn has indicated an increasing trend. The analysis of Nanning's characteristics of climate change based on meteorological monitoring data obtained in the medium and longterm can effectively contribute to optimize and adjust its industrial structure, and the perfection of global climate change response measures.

Key words: climate change, average temperature, precipitation, sunshine hours, Nanning, China
