摘要:
 为保护西咸新区生物多样性，给当地植物资源开发利用提供数据支持，通过野外调查和查阅文献，对西咸新区种子植物的物种组成和区系特点进行分析。结果表明：1）西咸新区共有种子植物112科353属671种，其中裸子植物4科8属21种，被子植物108科345属650种。2）单种科、单种属为该区系主要成分，而属和种则集中在中大型科和小属内。3）西咸新区种子植物的112科可划分为10个分布区类型，其中世界分布科40科，热带分布科36科（50.00%，不包含世界分布科，下同），温带分布科34科（47.22%），中国特有科2科（2.78%）；353属可划分为15个分布区类型，其中世界分布属50属，热带分布属96属（31.68%，不包含世界分布科，下同），温带分布属202属（66.67%），中国特有属5属（8.91%），属的分布型与科相比具有更明显的温带性质。综上所述，西咸新区植物资源丰富，生活型多样且以草本植物为主，地理成分复杂多样，植物区系具有一定古老性，表现出明显温带性质，并有由亚热带向温带过渡的区系特点。
Abstract:
 The objective of this study was to protect the biodiversity of Xixian New Area,and provide data support for the development and utilization of local plant resources.Through field investigation and literature review,the species composition and floristic characteristics of seed plants occurring in Xixian New Area were analyzed.It is found that 1) there are 671 seed plant species in Xixian New Area,belonging to 112 families and 353 genera.Among them,there are 8 genera,4 families,and 21 species in Gymnosperms,345 genera,108 families,and 650 species in Angiosperms.2) Single species genus and single species family are the main components of the fauna,while genera and species are concentrated in medium and large families and small genera.3) The 112 families of seed plants in Xixian New Area can be divided into 10 distribution area types,including 40 cosmopolitan families,36 tropical families (50.00%,not include cosmopolitan genera,the same below),34 temperate families (47.22%),and 2 endemic families in China (2.78%).The 353 genera can be divided into 15 distribution area types,including 50 cosmopolitan genera,96 tropical genera (31.68%,not include cosmopolitan genera),202 temperate genera (66.67%),and 5 endemic genera in China (8.91%).In summary,Xixian New Area is rich in plant resources,and the variety of life forms is mainly herbaceous.The geographical composition is complex and diverse,and the flora has a certain ancientness,showing obvious temperate nature,and has the characteristics of transition from subtropical to temperate.
