英文摘要：

As a consequence of recent global warming and its social impact, regional climate change is attracting an increasing amount of attention from scientists. A May-July temperature proxy extending back to 1836 was developed from tree-ring width of Chinese pine （Pinus tabulaeformis Carr.） found in the middle Ltiliang Mountains, northern China. Correlations with climatic data from six nearby meteorological stations range from -0.58 to -0.65, indicating a strong response of tree-ring index to May-July mean temperatures, which were subsequently reconstructed, The reconstruction captures 45% （F=38.474, P〈0.001） of the regional variance in the instrumental data over the calibration period 1955-2003. Reconstructed warm and cold periods were verified by additional temperature reconstructions based on tree-ring data from northern China. In addition, the reconstruction was significantly correlated with May-July mean temperatures from 13 other meteorological stations in northern China, suggesting that our reconstruction is also representative of north-central China. The warming trend during the second half of the 20th century is seen in the reconstruction, but only the 1994-2002 mean temperature seems unprecedented over the whole reconstructed period.
