1, world climate fluctuation in historical period
196 1 year, he wrote "World Climate Fluctuation in Historical Period", which is based on the geographical phenomena described in relevant documents, such as the attenuation of Arctic sea ice, the northward movement of the southern boundary of the Soviet permafrost zone, the retreat of the world alpine glaciers, and the rise of sea level.
It is proved that the climate gradually became warmer in the twentieth century, and the changes and fluctuations of the world climate in the historical period and the Quaternary as well as the changes of water, drought, cold and warmth in various countries are traced back. It is found that the cold period in the lower reaches of the Yangtze River in the second half of the 17th century is consistent with the "Little Ice Age" in Western Europe.
2. The relationship between meteorology and agriculture
In the research of meteorological science, Zhu Kezhen has always attached great importance to the relationship between meteorological climate and production and human life. As early as 1922, he published an academic paper on the relationship between meteorology and agriculture.
3. Natural language
The object of the lecture is phenology, because the whole text is centered on phenology. The full text is divided into four parts. By vividly introducing the phenological landscape of nature all year round, this paper leads to what phenology and phenology are, explains the importance of phenological observation to agriculture, explains the factors that determine the arrival of phenology, and explains the significance of studying phenology.
4. Bioclimatology
It is the representative work of Zhu Kezhen's popular science thought. According to the fact that phenology must serve the actual needs of agricultural production, he let readers know what is the law of phenology and its relationship with agricultural production, how to carry out phenological research and development prospects, and widely introduced the knowledge of phenology in ancient China and the development of phenology in various countries. His writing is popular and fluent, and he is very literary.
5. Preliminary study on climate change in China in recent 5,000 years.
A preliminary study on climate change in China in the last 5,000 years is world-famous, and it was immediately praised by scientific circles at home and abroad. Not only praised his scientific conclusions, but also praised him for pioneering the method of studying climate change with historical records and phenological data.
