摘要

对广西被子植物区系科的组成和地理成分进行了分析．结果表明，广西被子植物区系地理成分多样，而以热带科及热带至亚热带科占优势，两者合计占总科数的５３．７％；世界科和亚世界科、热带至温带科、温带科以及亚洲特有科分别占１９．４％，１２．０％，９．７％以及５．１％，这种复杂的地理成分是与广西的纬度地带性相适应的．该区被子植物的优势科分属于各类成分，而其表征科则大部分为热带亚热带科．表明在科级水平上，该区系是华夏植物区系的一部分

Abstract

An analysis of the angiospermous families in Guangxi shows that the flora has a diverse geographical elements

with an overwhelming number of tropical and tropical-to-subtropical families accounting for 53 7%; cosmopolitan and subcosmopolitan
