摘要:
利用1958年1月-2019年2月广西凤山县逐月降水量资料，采用线性回归法及复Morlet小波分析了凤山县近61a的降水变化特征。结果表明：（1）凤山县逐月多年平均降水量呈"单峰型"特征，降水主要集中在5-8月，其中最大月降水量值出现在6月份。（2）1958-2018年凤山县年冬春季降水量显著增多。年降水量和季节降量存在2-8a准周期变化。
Abstract:
Based on the monthly precipitation data from January 1958 to February 2019 in Fengshan County, the characteristics of precipitation change in recent 61 years in Fengshan County were analyzed by linear regression and Morlet wavelet analysis. The results showed that (1) the monthly average precipitation of Fengshan had a "single peak" feature, the precipitation was mainly concentrated in May to August, and the maximum monthly precipitation appeared in June. (2) In 1958-2018, annual precipitation, spring precipitation, autumn precipitation and winter precipitation in Fengshan County showed an upward trend, and summer precipitation decreased slightly; the trend changes of annual precipitation, summer precipitation and autumn precipitation were not significant, but the trends of spring precipitation and winter precipitation were significant. (3) From 1958 to 2018, the annual precipitation and autumn precipitation in Fengshan had a quasi-periodic change of 2-7 years, the spring precipitation had a quasi-periodic change of 2-8 years, and the summer and winter precipitation had a quasi-periodic change of 2-6 years.
