采用重建的合肥年冬季温度序列和降水序列分析了长江下游地区过去 30 0年的气候变化。在温度序列中 ,18世纪的大部分 ,19世纪中期和 2 0世纪的温度较为温暖 ,最暖的十年出现于 1990s ,而最冷的年代为 1870s ,该温度序列与邻近其它地区重建的温度序列具有很好的一致性。降水序列显示年至多年尺度的气候波动 ,湿期发生于1730s～ 176 0s ,1844～ 185 4年 ,186 6～ 1910年 ,而干期出现于 180 6～ 182 5年 ,185 5～ 186 7年 ,以及 2 0世纪的大部分。温度和降水间的关系表明 ,在年至十年尺度上 ,该地区气候变化主要以暖干或冷湿为主。
The climate change in the lower reaches of the Yangtze River in the past 30 years was analyzed by reconstructed annual winter temperature series and precipitation series in Hefei. In the temperature series, most of the 18th century, the mid-19th and 20th century temperatures were warmer and the warmest ten years appeared in the 1990s and the coldest ones were 1870s, which is similar to the temperature reconstructed in other parts of the world Sequence has good consistency. Precipitation series show climatic fluctuations from year to multi-year scales. The wet period occurs from 1730s to 176s, from 1844 to 185s, from 186s to 1910s, while in dry periods from 180s to 182s, from 185s to 186s , As well as most of the 20th century. The relationship between temperature and precipitation shows that climate change in the region is dominated mainly by warm-dry or cold-wetness over the years to ten years.
