Abstract: The interannual and spatial distributions of the climatic indicators affecting apple planting such as the air temperature, precipitation, relative humidity were analyzed, while climate trend rate and ArcGIS spatial interpolation were applied, based on 3h meteorological grid data of 5km × 5km spatial resolution from 1981 to 2010. In detail, the unplantable areas where climatic conditions cannot meet the basic requirements for apple cultivation were excluded firstly by one-vote veto indicator. Climatic suitability evaluation was carried out for plantable areas secondly with scoring standard for apple climatic regionalization factors. The interannual variation characteristics in the suitable for growing apples areas are analyzed finally. Findings are shown as below: apple can be grown in north China, northwest, southwest and parts of east and south China; in the plantable areas, the suitable regions were mainly located in most areas of the Loess Plateau and the Bohai rim area; the sub-suitable regions are mainly located in the North China Plain and a small part of the Loess Plateau, as well as the Tarim Basin and the Yunnan-Guizhou Plateau; the unsuitable regions are mainly distributed in the Northeast, most areas south of the Yangtze River, the Qinghai-Tibet Plateau, and parts of northern Xinjiang; Compared with the 1980s, in the 1990s and the 2000s, the Shandong Peninsula and the southern Loess Plateau had evolved from suitable planting regions into sub-optimal planting regions, however, the border areas between Liaoning and Mongolia, the Yunnan-Guichuan border areas, the northern Loess Plateau, and the border between Shaanxi and Gansu had evolved from the sub-suitable planting regions into the suitable planting regions. On the whole, the change was obvious that areas suitable for growing apples had moved northward and westward in China under the background of climate change.
