摘　　要：运用实地调查与文献查阅相结合的方法,对江苏省蓼属植物资源进行了统计与分析。江苏省蓼属植物共有36种(含变种),以一年生草本为主(80.56%)。该省蓼属植物可分为萹蓄组、刺蓼组、神血宁组、头状蓼组、拳参组和春蓼组,以春蓼组(38.89%)、刺蓼组(27.78%)和头状蓼组(11.11%)为主。依据生态类型,该省蓼属植物可划分为陆生型(20种)、湿生型(15种)和水生型(1种)。同时,制定了该省蓼属植物分类检索表。此外,从观叶、观花、观果等方面对该省蓼属植物观赏价值进行了分析,并通过分析蓼属植物在污染水体修复中的潜力讨论了其生态价值,以期为蓼属植物资源的开发利用提供借鉴和参考。Using the combination of field investigation and literature review,this paper sorts out and analyzes the resources of Polygonum in Jiangsu Province.There are 36 species(including variants)of Polygonum in Jiangsu Province,which are mainly annual herbs(80.56%).It can be divided into P.sect.Polygonum,Echinocaulon,Aconogonon,Cephalophilon,Bistorta and Persicaria.The first is P.sect.Persicaria,accounting for 38.89%,and the next are Echinocaulon(27.78%)and Cephalophilon(11.11%).According to the ecological type,the Polygonum in Jiangsu Province can be divided into terrestrial(20 species),wet(15 species)and aquatic(1 species)plants.At the same time,a key to Polygonum was developed.In addition,this study analyzes the ornamental value of Polygonum from the aspects of foliage,flower and fruit viewing,and discuss its ecological value by analyzing the potential of Polygonum to restore the polluted water,in order to provide references for the development and utilization of Polygonum.
