Abstract

Abstract: In order to understand the agricultural climate resources suitability of spring maize in Jilin province,temperature suitability (TS),precipitation suitability (PS),sunshine hour suitability (SS) and climate suitability (CS) models for the whole growing season,vegetative growth stage,and reproductive growth stage were established using a fuzzy mathematical method.Then the spatial and temporal distribution characteristics of TS,PS,SS,and CS were analyzed.The results show that,in recent 50 years,the TS for the whole growing season of spring maize in Jilin province is generally more than 0.70 with an increasing trend,which is suitable for maize growing as a whole.TS is higher in western Jilin and lower in eastern Jilin.The distributions of the TS at vegetative and reproductive growth stages are in consistent with that of the whole growing season.The SS at each growth stage of spring maize in Jilin province is higher with the value between 0.80 and 1.00.SS is higher in western Jilin and lower in western Jilin.The PS of spring maize at each growth stage is between 0.40 and 0.60,which has larger variation.CS for the whole growing season of spring maize is between 0.60 and 0.75.CS of vegetative growth stage,mostly above 0.70,is higher than that of the whole growing season.However,CS of reproductive growth stage,mostly below 0.70,is lower than that of the whole growing season.For CS of maize in Jilin province,there are no obvious differences between areas.CS of each growth stage shows a decreasing trend though they have not passed the significant test.

Key words: Temperature suitability, Precipitation suitability, Sunshine hour suitability, Climate suitability
