摘　　要：基于1971—2015年浙江省66个气象台站的逐日地面气象观测资料,分析了茶叶生长气候资源的时空分布特征。结果表明:近45年来浙江气候变化明显,年平均气温、≥10℃活动积温呈上升趋势,降水量波动明显,整体略增加,日照时数以60.6 h/10 d的速率减少;应用Mann-Kendall法检验,1994年为气温突变点,突变后全省春季平均气温增加了1.1℃,导致春茶开采时间提前8天左右。研究结论可为茶叶生产适应气候变化采取措施提供依据。By using daily meteorological data of 1971-2015 from 66 meteorological stations in Zhejiang, thespatio-temporal characteristics of climate resources for tea growth were analyzed. The results showed that：climate changed obviously in recent 45 years, with the average temperature and ≥10℃ accumulatedtemperature increasing; what＇s more, the rainfall fluctuated obviously with a little increasing trend, while thesunshine hours decreased with the rate of 60.6 h/10 d; according to the Mann-Kendall test, the mutation pointof temperature was in 1994; after the mutation, the temperature increased by 1.1℃, which contributed to thepicking time 8 days in advance. The results would provide certain references for adapting to climate changeduring tea production.
