Abstract: Professor Zhu Kezhen(Co-Ching Chu,1890-1974)was an outstanding scientist and educator. His research covered three fields including meteorology, geography and history of natural science. He published about 300 papers related to these fields. The his-toric climatic change in China was a subject which he most intensively studied. Eight pa-pers related to this subject were published by Professor Zhu Kezhen from 1925 to 1972. The last brilliant paper on the title"A Primary Study on Climatic Change in Past 5000 Years in China "reconstructed the climatic change history based on temperature index, particularly on winter temperature index. He concluded that the temperature was 2℃ higher in 5000-3000a B. P. than that at present and temperature in January was 3-5℃ higher then. He found that.in the latest 3000 years,there were major cycles of 400-800 years with an amplitude of 1-2℃ and small cycles of 50-100 years with an amplitude of 0.5-1.0℃. The temperature curves of the past 5000 years which Zhu Kezhen recon-structed in China basically alike the δ18O record from Camp Century Ice Core in Green-land. He was particularly good at analysing and summarizing historic data of phenology, archeology and meteorology and comparing with that at present. He also closely fol-lowed the international progress in science and technology. He considered that the study of historic climatic change was very useful to the forecast of future climatic change. His method in research and achievement opened up a new path for the study on the climatic change in China.
