在广泛调查山樱花地理分布信息的基础上，利用目前常用气候指标，对山樱花地理分布及其与气候的关系进行了研究。结果表明：山樱花分布于东亚温带（102～141° E，23～40° N），海拔50～1800 m之间。气候环境指标的研究结果显示山樱花热量分布范围整体偏低，在中国的热量分布范围要远大于朝鲜半岛-日本的分布。根据主成分分析可知，影响山樱花分布的重要环境因子为年均温、纬度、极端低温、1月均温和海拔。热量因子中年均温在7?91～17?92℃，极端低温不低于-17?3℃，1月均温-6?31～8?48℃的区域范围内适于山樱花的生长。基于此，提出山樱花分布的7大区域，包括中国西南地区、华中地区、华南北部及华东南部地区、华北及东北南部地区和台湾地区，以及朝鲜半岛地区、日本地区，并得到主成分分析图的支持。

Based on the geographical distribution information of Cerasus serrulata, the interaction of vegetations and cli-mates have been studied by 13 widely used indices. The results showed, the distribution region of C. serrulata was tem-perate East Asian, it was 23-40°N, 102-141°E, and the elevation range was 50-1 800 meters. The climatic indices showed that the tree have a low heat range,and the range of heat distribution in China is much wider than in the Korean Peninsula-Japan distribution. The result of principal component analysis revealed that annual mean temperature,latitude, coldest temperature,average temperature of January and elevation ranges was the most important environment factors to influence the distribution. The suitable heat factors for the growth of C. serrulata was the range of annual mean tempera-ture between 7?91-17?92 ℃, coldest temperature not less than 17?3 ℃, average temperature of January between 6?31 ℃ and 8?48℃. Supported by the two dimensional plot of principle components on climatic factors, we divided the distribution region into 7 parts, including the region of Southwest China, Central China, north of South China and south of East China, Northeast China, Taiwan of China, Korean Peninsula, Japan.
