摘　　要：分布区类型是指植物类群的分布图式基本一致地再现。分布区类型的划分是植物区系地理学研究的重要方法。中国种子植物的 3116个属被划分为 15个类型和 37个变型 ,用固定的格式代表各种分布区。植物分布区类型的划分方法已经被实践证明是揭示各分布区类型的特征及其相互关系行之有效的方法。本文对世界所有种子植物的科进行了分析整理 ,提出了世界种子植物科分布区类型的划分方案。将世界种子植物的科划分为 18个大分布区类型 ,并沿用中国种子植物属分布区类型的表现方式 ,用数字 1～ 18代表不同的分布区类型 ,其中1～ 15与中国种子植物属分布区类型完全一致 ,16～ 18是中国没有分布的科。除 1,11,(16 ) ,(17) ,(18)外 ,均有或多或少的变型 ,共 74个。本文还提供了世界种子植物各科的分布区类型表。这种划分对理解世界被子植物区系的形成发展有一定帮助 ,并为陆地植物分区的深入研究提供了一个有效的手段。The areal-type means distribution map of certain plants always same or nearly same. This is an important method in floristic research to divide distribution into different areal-types.More than 3116 genera of seed plants have been recorded in China.They have been classified into 15 areal-types and 37 subtypes.The certain number represent certain areal type such as number 2 always means pantropic distribution pattern.After repeated to tests and uses,it has been proved that characteristics and relationships of each areal type can be showen by such classification.A classification precept of families of seed plants of the world has been proposed at present paper.The families of seed plants of the world can classified into 18 areal types and 74 subtypes.Among these areal-types,areal-types 1 to 15 are coincidence with those of Chinese seed plants.Areal-type 16-18 are the kinds of distribution pattern which can not be found in China.A distribution patterns of world families of seed plants is listed at present paper as well.This classification is a key to help us to understand development of flora of seed plants of the world and become a base of regionalization of world flora.
