Scientific dendrochronology was established by the American astronomer Dr. Douglass in the early 20th century; since then it has been applied by world scientists in many research fields. At present in Germany and U. S. A., there is the synthetic chronology tracing to 10,000 BP; in Japan, a synthetic chronology can trace to 4000 BC and more. Scientists have used dendrochronologies with long sequences in the study and dating of past cultures, as well as in researches on climates (including temperature and rainfall), ecological conditions, the cultivation of forests, plant diseases and insect pests,and environmental pollution. The present paper makes a brief summarization of the definition, principles and significance of chronology and the progress of dendrochronological studies at home and abroad, and points out problems in Chinese dendrodating and the measures of their solution.
