Abstract: In order to study the influence of climatic resource on the apple’s yield, based on the data of apple’s yield in Qinzhou district and the data of mean temperature, precipitation, sunshine in apple’s main growth period from April to August at Tianshui weather station, we analyzed the variation characteristics of meteorological factors and their effects on production and established the comprehensive climatic resource index. The result showed that the variation range of heat resource in early stage was larger than that in the later stage of apple’s growth period in recent 30 years. The chilling damage before the fruit setting period had strong effect on apple’s production. The variation of precipitation during April to June had a downward trend and that during July to August had no obviously liner variation from 1981 to 2010. It also showed that the sunshine duration from April to June increased from 1981 to 2010 and had no obviously liner variation from 1981 to 2010. The relationship between the yield and comprehensive climatic resource index were remarkably consistent. It indicated that the comprehensive climatic resource was not suitable for apple’s production in 1990’s and had good effect in early 21th century. We supposed that the variation trend of climate would be beneficial to the apple’s production in the future.
