我国三十年代以来,特别是建国以来,在竺可桢教授领导下,建立了全国性的物候观测网,并在《物候学》一书中,对自然历及物候季节划分方面作了系统的论述。宛敏谓同志在此基础上,1983年5月进一步提出了以日平均气温与物候现象相结合的划分四季标准,实践证明该标准符合自然界的实际情况。全国各地已陆续依此划分四季编制自然历。我们于1982年参加了全国物候观测协作网的活动,先后进行了80多种植物及有关动物气象要素的观测。本文根据1982—1984年以及西北农学院王谦等
Since the founding of the People’s Republic of China in the 1930s, especially under the leadership of Professor Zhu Kezhen, a nationwide network of phenological observations has been established. In his book “Phenology,” a systematic exposition of the natural calendar and the seasonal division of phenology has been made. On the basis of this, Comrade Wan Min said that in May 1983, the four seasons of dividing the daily average temperature and phenological phenomena were further proposed, and the practice proves that the standard is in line with the actual situation in nature. All over the country have been in accordance with the preparation of natural calendar four seasons. We participated in the activities of the National Collaborative Observatory of Phenological Observatories in 1982 and conducted observations on more than 80 species of plant and related animal meteorological elements.
