摘要： 探讨了沈阳市区植物区系特点和城市植被类型的分类及其特征，沈阳市处于长白植物区系、蒙古植物区系和华北植物区系交汇地带，植物种类较丰富，约有种子植物98科371属779种，最大科是菊科。共有植物85种，超过20种的科还有莎草科、蔷薇科、豆科、蓼科、唇形科、百合科及毛茛科等，这些科共有植物384种，占沈阳市区种子植物总数的49．3％。此区系有23个地理成分类型，其中以温带性质占优势。占沈阳市区地理成分的89．3％，根据植被发生和功能以及建群种的作用，将沈阳市区城市植被划分三大植被类14个植被组和57个植被型，并对3个植被类中的典型代表性类型进行了群落(种群)的组成、结构、动态和功能分析。

Abstract: Shenyang city is located in the intersect zone among Changbai，M ongolia and North China flora，which has a plenty of plant species belonging tO 98 families ，371 genera and 779 species ． There are 85 plant species in the
