| 摘 要： | We review here proxy records of temperature and precipitation in China during the Holocene, especially the last two millennia. The quality of proxy data, methodology of reconstruction, and uncertainties in reconstruction were emphasized in comparing different temperature and precipitation reconstruction and clarifying temporal and spatial patterns of temperature and precipitation during the Holocene. The Holocene climate was generally warm and wet. The warmest period occurred in 9.6-6.2 cal ka BP, whereas a period of maximum monsoon precipitation started at about 11.0 cal ka BP and lasted until about 8.0-5.0 cal ka BP. There were a series of millennial-scale cold or dry events superimposed on the general trend of climate changes. During past two millennia, a warming trend in the 20th century was clearly detected, but the warming magnitude was smaller than the maximum level of the Medieval Warm Period and the Middle Holocene. Cold conditions occurred over the whole of China during the Little Ice Age （AD 1400-AD 1900）, but the warming of the Medieval Warm Period （AD 900-AD 1300） was not distinct in China, especially west China. The spatial pattern of precipitation showed significant regional differences in China, especially east China. The modern warm period has lasted 20 years from 1987 to 2006. Bi-decadal oscillation in precipitation variability was apparent over China during the 20th century. Solar activity and volcanic eruptions both were major forcings governing the climate variability during the last millennium.

| Abstract: | We review here proxy records of temperature and precipitation in
China during the Holocene, especially the last two millennia. The quality of
proxy data, methodology of reconstruction, and uncertainties in reconstruction
were emphasized in comparing different temperature and precipitation
reconstruction and clarifying temporal and spatial patterns of temperature and
precipitation during the Holocene. The Holocene climate was generally warm and
wet. The warmest period occurred in 9.6--6.2 cal ka BP, whereas a period of
maximum monsoon precipitation started at about 11.0 cal ka BP and lasted until
about 8.0--5.0 cal ka BP. There were a series of millennial-scale cold or dry
events superimposed on the general trend of climate changes. During past two
millennia, a warming trend in the 20th century was clearly detected, but the
warming magnitude was smaller than the maximum level of the Medieval Warm
Period and the Middle Holocene. Cold conditions occurred over the whole of
China during the Little Ice Age (AD 1400--AD 1900), but the warming of the
Medieval Warm Period (AD 900--AD 1300) was not distinct in China, especially
west China. The spatial pattern of precipitation showed significant regional
differences in China, especially east China. The modern warm period has lasted
20 years from 1987 to 2006. Bi-decadal oscillation in precipitation variability
was apparent over China during the 20th century. Solar activity and volcanic
eruptions both were major forcings governing the climate variability during the
last millennium.We review here proxy records of temperature and precipitation in
