Abstract: The budding and blooming data of a plant usually bring a climatic message of seasonal shift. Based on the phenological observations of 50 stations in China during 1963-1972, geographical distribution pattern of phenodate of 20 plants for spring, summer and autumn are taken into account, and the Hopkins’ Bio-climatic Law modified.It is shown in this paper that the phenodate for spring will be delayed 3.8 days every degree in latitude northward, 3.5 days every degree in longitude eastward, and 1.5 days every 400 feet upward. These ranges for longitude and height are smaller than that given by Hop-kins.Distribution of phenodate is not only a question of latitude, longitude and height, but also correlated with seasons. The days delayed every degree in latitude northward are as follows: 4-5 days before the end of February, 3-4 days for March and April, 2-3 days from the end of April to the middle of June, less than 1 day from the middle of June to the middle of July. After the middle of July the trend of the relationship between phenodate and latitude are reversed, that is, the more northward the latitude, the earlier the phenodate. The relationship between the phenodate and longitude and height show similar trend, but with a smaller amplitude.Empirical formula and alignment chart for the geographical distribution of phenodate are developed.
