| 1 | Some evidence of drying trend over northern China from 1951 to 2004显示文摘The surface wetness index, Palmer drought sererity index and the retrieval of soil moisture over China were calculated using monthly precipitation and monthly mean surface air temperature. Based on the contrast analysis of the variation of the above three indices and precipitation, the dry/wet spatio-temporal pattern of northern China in the last 54 years was revealed, and the evidence of drying trend over northern China was analyzed, especially. The results show the following four facts: (1) The drying trend is the main characteristic of the eastern part of Northwest China and the central part of North China since the 1980s and it was enhanced in the last 15 years mainly due to the precipitation decrease and the temperature increase; (2) During the last 54 years, there was only one dry/wet shift at the interdecadal scale occurring in the eastern part of Northwest China and the central part of North China in the late 1970s, which was related to 1977/1978 global abrupt change, whereas there were three shifts in Northeast China, one was in the mid 1990s and the other two were in 1965 and 1983, respectively; (3) Unlike the variation trend of other subregions of northern China, the western part of Northwest China is currently located in a relatively wetting period, which is weak-ened due to the temperature increase; (4) The extreme drought frequency is obviously increasing in the eastern part of Northwest China, the central part of North China and Northeast China since the 1980s, which is closely related to the precipitation decrease and temperature increase in these subregions. | MA Zhuguo1,2 & FU Congbin1,2 1.

| 2 | Correlations between North Atlantic Oscillation Index in winter and eastern China Flood/Drought Index in summer in the last 530 years显示文摘The time series of winter North Atlantic Oscil-lation Index (NAOI) in the period of 1429-1983 developed by Glueck and summer Flood/Drought Index (FDI) of eastern China in the period of 1470-1999 from 100 stations are used in this paper to study the potential impact of North Atlantic Oscillation on the climate in China. The analysis has ex-plored some significant lag correlations between FDI and NAOI. The maximum positive correlation coefficients be-tween NAOI and area-mean FDI in eastern and northern China lagging 2-3 years reach at 0.001 significance level, and while there are also negative correlation between NAOI and FDI in central and southern China at significance level of 0.05-0.01. The correlation between FDI and NAOI is time-dependent, i.e. the correlation coefficients between two indices vary from period to period. The highest correlation appeared in the period of 1636-1742, around the Little Ice Age, with the significant level of far above 0.001. The second significant period was from 1951 to 1999, at the level of 0.005-0.002. Both the power spectrum analysis and Morlet wavelet transformation have presented an interesting phe-nomenon: the area-mean FDIs in eastern and northern China share almost the same oscillation periods with NAOI in the inter-annual, decadal and centurial scales’ oscillations, i.e. 4-5, about 10, 20-30, around 50 and 80-100 years, etc. The Mann-Kendall Rank Statistic test reveals the significant trend and decadal abrupt changes in the series of area-mean FDIs in eastern and northern China in the past 530 years, while the NAOI in the past 400 years, did not show such trend at the significance level, but presented more frequent changes than those of FDI in China. This difference is per-haps due to the fact that the amplitude of the extremes of reconstructed NAOI series is less than that from instrumen-tal records. | FU Congbin & ZENG Zhaomei Key Laboratory of Regional Climate-Environment for Temperate East Asia, Institute of Atmospheric Physics, Chinese Academy of Sciences START Regional Center for Temperate East Asia, Beijing 100029, China | 2005 | Chinese Science Bulletin2005，50，21： | 9 |
| 3 | Impact of climate change on dynamic of plant communities, lakes and swamps in Beijing area during Holocene period显示文摘From 400-60 cm 26 samples were obtained in an 820 cm profile at Dongganchi of Fangshan in Beijing. They provided a continuous record of vegetation and environmental changes over ca .7000 aB.P., as inferred from Spore-pollen. loss-on-ignition (LOI), and charcoal analysis,impacts of natural fire and human activities on plant communities and lakes and swamps were considered. 1) From 7000-5960 aB.P, the forest development was limited, probably in response to climate Warming. Aquatic and marsh plants began to increase, bat the lakes and swamps in some areas were limited. 2) About 5960-3390 aB.p, presumably in responded to climate warming which was warmer than that at present Aquatic plants began to become abundant,reflected the widespread development of the lakes and swamps, the climate was wet with annual precipitation higher than that at present 3) About 3390-1000 aB.P, human activities have kept to be the dominating factor in the evolution of vegetation and climatic change. Temperature decreased, and the annual precipitation rapidly reduced in Baijing area. the lakes and swamps gradually shrank back, some of them even disappeared. 4) After 1000 aB.P, there was a severe fluntuction, and early during this time, it was comparatively warm and humid, but became cool and dry later. In the meantime. human activities were intensified. agricultural activity was flourished. and large area of water field was | Zhang jia-hua Kong Zhao-chen Fu Cong-bin (START, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029,China.
