摘要： 作物气候评价的定量化是农业气象业务发展的必然趋势。本文运用模糊数学理论，分别建立了气温、降水量和日照时数对昆明蚕豆生长发育适宜程度的隶属函数模型，据此模型分别计算蚕豆不同生育阶段的温度、降水、日照及光温水综合因子对蚕豆生长发育的隶属度，达到定量评价蚕豆生育期气象条件的目的。对2007年度和2008年度各气象因子进行计算，得出：温度和日照的隶属度较高，而降水隶属度较低且变化幅度较大，说明温度和日照条件能够满足蚕豆生长发育的需要，自然降水偏少是蚕豆产量形成的限制因子。

Abstract: The quantitative evaluation of Crop Climate is an inevitable trend in the development of agrometeorological services. By using fuzzy mathematics theory, the membership function model of temperature, precipitation and sunshine time for broad bean were established, and the membership degree of temperature, precipitation and sunshine in the growth nand development of broad bean was calculated to estimate the climatic suitability to broad bean quantitatively. The meteorological factors during growth and development of broad bean in 2007 and 2008 was calculated, results indicated that the membership degree for the temperature and sunshine was relative high, but for the precipitation was low with large variable extents. These explained that the temperature and sunshine were able to satisfy the growth and development of broad bean. The lack of the natural precipitation was a limited factor for the formation of the broad bean yield.
