的逐日平均气温、日照时数、降水量、相对湿度等资料，分析气候变暖背景下皖南山区茶叶生长热量、光照、

年平均气温、≥ 10 ℃活动积温和适宜生长日数增幅分别为 0.29 ℃ /10 年、111.7 ℃ /10 年和 2.7 d/10 年；光照
资源极显著减少，年均日照时数降幅为 57.5 h/10 年；降水资源变化不一，其中降水量呈增加趋势、增幅为 13.7

| 【Objective】By analyzing the variation characteristics of climate resources during tea growing season in
southern Anhui under the background of climate warming, the study aimed to provide a scientific basis for the rational use
of climate resources and response to climate change during tea production in southern Anhui.【Method】Based on the data
including daily average temperature, sunshine hours, precipitation and relative humidity from 19 meteorological stations in
southern Anhui during 1971-2019, the study analyzed the variation characteristics of climate resources including heat, light
and precipitation during the tea growing season as well as the tea harvesting period in mountain areas of southern Anhui.
【Result】The heat resource during the growth of tea increased obviously in mountain areas of southern Anhui in recent 50
years, in which the annual average temperature, the accumulated temperature above 10℃ , and the number of suitable days
for tea growth increased per 10 years by 0.29℃ , 111.7℃ and 2.7 d, respectively. The light resource decreased significantly,
and the decreasing range of annual sunshine hours was 57.5 h per 10 yaers. The variation of precipitation resources varied
among the precipitation and relative humidity, the former increased insignificantly by 13.7mm per 10 yaers, and the latter decreased significantly by 0.5% per 10 yaers.【Conclusion】Due to the climate warming, the harvesting periods of early and
middle-late growing tea was significantly advanced by 4.2 d and 3.6 d per 10 yaers, respectively. The changes of temperature
and precipitation caused by climate warming have a great impact on yield per mu of tea in mountain areas of southern Anhui. |
