Research report on the relationship between climate and weather

The research object of phenology is to investigate the differences between north and south, between east and west, between vertical and ancient times. This paper expounds the relationship between climate change and animals and plants from the time and space distribution, finds the laws from it, and uses these laws to study the changing laws of nature and guide production activities. For example, the phenology is used to divide the four seasons, and the natural calendar is used to predict the agricultural time. In the division of physical geography, we should also take phenology as the basis.

As early as 3000 years ago in the early Western Zhou Dynasty, China had a monograph on phenology, Xia. During the Warring States Period, Lu's Spring and Autumn Annals, Bi Sheng Shu in the former Han Dynasty, Yue Ling in the later Han Dynasty and Qi Shu in the northern Wei Dynasty all talked about the suitable period of field operations such as sowing, ploughing and harvesting, and most of them took the phenology of nature as the control standard. Modern phenology was initiated by Zhu Kezhen, a famous scientist in China. In 193 1, Zhu Kezhen summarized the achievements of ancient phenology in China and put forward a new method for phenological observation. 196 1 year, the national phenological observation network was established and the phenological observation methods were formulated. 1968 published the book Phenology. From 65438 to 0973, Zhu Kezhen's famous paper "A Preliminary Study on Climate Change in China in Recent Five Thousand Years" applied phenological methods to analyze climate change, which aroused strong repercussions at home and abroad.

Phenology originated earlier in foreign countries. In Europe and Greece, the Athenians made a lunar calendar containing a year's phenology. Japan began to record the flowering date of cherry blossoms in August12, with a history of 1 100 years. The countries that have done a good job in phenology in the world are Japan, Germany, the United States and the Soviet Union.
