摘要
通过实地调查和收集资料，总结分析了冬樱花（Ｃｅｒａｓｕｓｃｅｒａｓｏｉｄｅｓ）生态学特性及其地理分布概况和特点．在统计地理气象因子原始数据的基础上，应用多元性回归、主成分分析（ＰＣＡ）等数学方法，建立了冬樱花自然分布模型，并通过实例证明了该模型的有效性，为冬樱花的引种和发展提供了理论基础．
The ecological and distribution features of Cerasus cerassoides are described and
analyzed.Furthermore,the natural distribution models are established on the basis of
meteorological factors as the indicators and applying mathematical methods such as
MLR(Multivariate Linear Recurrence) and PCA(Principal Component Analysis).These models are
proved to be effective by means of natural distribution places.
