Crop production and natural conditiOns are closely related, it is direCtly related to the comprehensive development of Hunan Provinceo I-conduct a comprehensive measure and compare use of principal component analysis of the contribution rate and the volume of load factor from temperature, precipitation, sunshine hours, the area of arable land four indicators of 14 cities in Hunan Province .The results showed that the total output of croos is higher in Changde, Hengyang, Shaoyang, and lower crop yields in Zhangjiajie, western Hunan.
