Abstract: Based on the information of geographical plantation for kiwifruits (Actinidia deliciosa and Actinidia chinensis) in 171 counties in the Chinese mainland in 2013, and the meteorological data of 2084 stations from 1981 to 2010, 9 factors that might have potential influence on the distribution of the kiwifruit plantation were selected considering the combination of its physiological demand and quality formation. And the relationship between potential distribution of the kiwifruit plantation and climatic factors was established by using the maximum entropy (MaxEnt) model via ArcGIS. Then, the dominant climatic factors and their appropriate ranges that affect the distribution of kiwifruit plantation were investigated. And the region of climatic suitability for the kiwifruit plantation was divided basing on presence probability. The results showed that the dominant climatic factors affecting the distribution of the kiwifruit plantation in China were the coldest monthly mean temperature, annual sunshine hours, annual relative humidity, hottest monthly mean temperature, frost-free duration and precipitation, the frost-free duration, and the coldest average temperature. The suitable region of the kiwifruit was mainly located within east of 102°E and 24-36°N. Among them, the most suitable region included mainly the middle and eastern parts of Sichuan, mid-western parts of Chongqing, Guizhou Plateau, the southwest of Hunan and the north of Qinling Mountains. Hunan, Hubei and Chongqing were the more suitable region that has higher climate adaptability for further development. The north of Qinling Mountain and northwest Sichuan, where were widely cultivated up to data, should be controlled to a proper scale and enhanced the quality and benefit of the kiwifruit plantation.
