中文摘要	对甘肃省荒漠区种子植物属的组成及其区系特征进行了研究.结果表明:甘肃省荒漠区分布有种子植物228属,其区系特征为单种属和寡种属多,优势现象明显,植物区系具有温带荒漠性和古老性;区系地理成分复杂多样,包含9个分布区类型和13个变型,温带成分(包括北温带分布及其变型、旧大陆温带分布及其变型和温带亚洲分布)占有绝对优势,占总属的33.76%;地中海区-西亚-中亚分布也是主要的组成部分,占总属的28.98%,特有成分比较低,中国特有成分仅4属,只占总属数的1.57%,起源古老,多为本土发生.
英文摘要	In order to analyze the composition and feature of spermatophyte genera in the desertification area in Gansu Province and explore their origin,authors of this article conducted a long-term survey.The results and ample,relevant data show that the seed plants distributed in the desertification area are of 228 genera, whose flora feature is dominated by one-seeded and depauperated genera,with marked phenomenon of superiority;that the flora owns tropical desertification and antiquity and the floristic geographical composition is complex and diversified,covering 9 distribution zones and 13 variable types;that among them,tropical components play a dominant role,occupying 33.76% of the total;that the distributions of the Mediterranean-West-Asia-Central-Asia is also one of the main component flora in this area,taking up 28.95%;and that particular components occupy a lower percentage,with Chinese endemic genera being only 4,taking up only 1.57 % of the total and mostly taking place indigenously with ancient origin.
