Climatic regionalization of high acid apple is studied, which can provide scientific and technological support for the rational distribution of the planting base of high acid apple in Ningxia. Based on the previous research results, the climatic zoning index and zoning principles of the high acid apple in Ningxia are established. Meteorological observation data of 30 year (1981 to 2010) of 23 meteorological stations in Ningxia are collected. According to the ≥10 ℃ active accumulated temperature, annual mean temperature, sunshine duration from July to September, daily temperature range from July to September，the refined climate zoning map of the high acid apple is given. The results show that in the Yellow River irrigation area and the Qingshui River basin of the middle arid belt are more suitable for latematuring high acid apple，and most areas in central and southern mountainous areas are not suitable for planting latematuring high acid apple.
