Abstract: Based on the precipitation data from 4 meteorological stations in Huizhou from 1971 to 2017, the drought tendency from October to March was analyzed using standardized precipitation index (SPI), Mann- Kendall method and wavelet analysis. The results indicated that the precipitation tendency declined from 1971 to 2004 and increased from 2004 to 2017. The drought condition in dry season was normal, while it showed slight drought in seasonal drought, then was medium drought, severe and extreme drought were not found. The conversion of dry and wet in dry season was jumping, and 1975 was the jumping year from wet to dry, and 2015 was the jumping year from dry to wet. The main oscillation cycle was 15 to 32 and 5 to 15 years of dry-wet in dry season, there were seven dry-wet alternation of 10 years scale in recent 47 years, and the isoline (with wavelet coefficient＞0) was not entirely closed, indicating that it would still have a wetting trend in a few years in Huizhou dry season.
