Abstract: Analyses the relationship between the growth of Calophyllum inophyllum L. and the meteorological conditions.Through simple correlation and progressive regression analysis, with circs of leaves growth, sets up the mathematical simulation model between diameter, height growth of Calophyllum inophyllum L.and meteorological conditions, educes the appropriate meteorological conditions indexes of Calophyllum inophyllum L.. Researches that Calophyllum inophyllum L grows best under the following conditions:the monthly average temperature above 25℃, monthly minimum temperature below 18 ℃, monthly precipitation over 160 mm.. suface temperature below 33 ℃, amount of evaporation below 200mm. It appears no pullulation of Calophyllum inophyllum L. when monthly minimum temperature below 10 ℃ and monthly precipitation below 50 mm.
