這些自然現(xiàn)象，我國古代勞動人民稱它為物候（phenological phenomena）。物候知識在我國起源很早。古代流傳下來的許多農(nóng)諺就包含了豐富的物候知識。到了近代，利用物候知識來研究農(nóng)業(yè)生產(chǎn)，已經(jīng)發(fā)展為一門科學(xué)，就是物候?qū)W（phenology）。物候?qū)W記錄植物的生長榮枯，動物的養(yǎng)育往來，如桃花開、燕子來等自然現(xiàn)象，從而了解隨著時(shí)節(jié)推移的氣候變化和這種變化對動植物的影響。
These natural phenomena are referred to as phenological phenomena by working people in ancient China. Phenological knowledge has a long history in our country, and it can be found in many farmers’ proverbs which were handed down from the ancient times. In modern times the phenological knowledge is used to study agriculture production and then develops into a science, phenology. It keeps a record of the growth and development of plants and animals, such as the blossoming of peach flowers or the returning of swallows, and consequently facilitates our understanding of the climate change as time passes and its impacts on flora and fauna.
