BC137-AD2000中国东中部干湿指数
收藏资源简介:
利用历史文献记载重建的公元初年前后至20世纪末中国东中部(25°-40°N , 105°E 以东)及3个子区域(包括华北,约34°-40°N、江淮,约31°-34°N、江南,约25°-31°N)干湿变化序列,共4条;重建结果为每个区域10年滑动的标准化干湿指数,各序列的起始时间分别为:AD101-110(东中部),BC137-128(华北),AD9-18(江淮),AD101-110(江南);终止时间均为:AD1991-2000年。
Four dry-wet variation series, reconstructed using historical documentary records, span the period from around the early 1st century AD to the end of the 20th century for east-central China (25°–40°N, east of 105°E) and its three sub-regions: North China (approx. 34°–40°N), Jianghuai (approx. 31°–34°N), and Jiangnan (approx. 25°–31°N). The reconstruction results are 10-year moving standardized dry-wet indices for each region. The starting timepoints of the four series are respectively: AD 101–110 for east-central China, 137 BC–128 BC for North China, AD 9–18 for Jianghuai, and AD 101–110 for Jiangnan. The ending time for all series is uniformly AD 1991–2000.
