按照气温变化规律将中国气温变化划分为东北、华北北部、华东华南、华南、陕甘宁、川黔桂、新疆和滇藏高原区等8个分区.搜集有确切年代和气温数值的古气温记录1397条,以8个分区为单元进行整理,以日历年时间为坐标系,采用单样本区域订正—多样本平均集成法重建了东北、华北北部、华东华南、华南和滇藏高原区的全新世200 a分辨率连续集成气温序列.结果表明:5条分区连续气温序列与所在区域的高分辨率环境记录变化趋势基本一致,主要的百年尺度冷暖事件有较高的可比性;5条分区连续序列指示全新世气温变化可以分为明显的早期升温、中期大暖期和晚期变冷3个阶段;气温变化幅度区域差异较大,但主要的冷暖事件基本一致,暖期盛期发生在8~6 ka BP,当时滇藏高原约比现代高2℃,东北高出3℃,华北北部高1.5℃,华东华南接近1℃,华南区仅高出0.5℃;主要冷事件发生在9.2、6.2、4.0和0.4 ka BP,其中,4.0 ka BP冷事件规模较大,滇藏高原、东北、华北北部、华东华南和华南区降低幅度分别为1.5、2、1、0.5和0.5℃.全新世期间各分区气温变化幅度也表现出纬度从北向南、海拔从高到低、气温变化幅度依次递减的特征.%Based on the distribution of temperature changes of China which is divided into the Northeast China, northern North China, mid-eastern China, South China, Shaanxi-Gansu-Ningxia area, southwest area, Xinjiang and Yunnan-Tibet Plateau eight regional temperature series. Collecting information on the exact age and temperature values of the ancient temperature records 1397 as the units of eight distribution is used to make up and coordinate the calendar year, named converted single sample from local to regional and averaged by the multiple samples. Using data of the Northeast China, northern North China, mid-eastern China, South China and Yunnan-Tibet Plateau, 200 years of the Holocene temperature resolution of continuous integration sequence were established. The results showed that; Five district areas where continuous temperature series and the trend of high-resolution environmental records are basically the same, the major centennial-scale cold and warm events have a higher comparability; five consecutive sequences of instructions area of the Holocene temperature changes can be divided into temperature was in the early, mid and late three stages; Large regional differences in rate of temperature change, but the main events are basically the same cold and warm, and peak warm period occurred in 8 ~ 6 ka BP. The Yunnan-Tibet Plateau was higher than modern about 2 ℃ , higher than the Northeast China 3 ℃ , north of North China 1.5 ℃ , East China close to 1 ℃ , higher than the Southeast only 0. 5 ℃ ; Major cold events occurred in 9. 2, 6. 2, 4. 0 and 0. 4 ka BP, 4 ka BP is a cold event largescale cold event. The Yunnan-Tibet Plateau, Northeast China, northern North China, North China, east China and Southeast China had a temperature reduction of 1. 5, 2, 1 and 0. 5 ℃. In the extent. The Holocene temperature changes in the district during the period also show that the latitude range from north to south, from high to low altitude, followed by decreasing rate of temperature change characteristics.
