摘　　要：采用普遍调查、样方和样线调查相结合的方法,通过对江苏省莎草科(Cyperaceae)植物多次实地调查并查阅文献资料,分析其物种多样性、分布特点、分布格局及资源应用价值,以期建立江苏省莎草科植物种质资源库,了解其分布特征、资源应用现状,进而保护其物种多样性并进一步开发利用。调查分析结果表明:江苏省莎草科植物共16属116种,其中7变种,香附子、碎米莎草等10种植物在江苏省普遍分布,分布范围广泛,物种丰富度较高;在属和种的分布类型上以世界分布、泛热带分布和温带亚洲分布为主,具有亚热带向温带过渡的性质;其分布中心在连云港、盐城及南京、常州一带;且集中分布在低海拔段;此研究可为莎草科植物资源的科学收集、有效保护、评价和利用提供科学依据。We used the combined method of general survey surveys, qua-drat and transects method, investigated the Cyperaceae plant resources in Jiangsu Province by several field surveys and reviewing of literature, analysed the spe- cies diversity, distribution characteristics, distribution patterns and resource value. In order to establish the Cyper- aceae plants germplasm bank, understand the distribution of resources application status, and then protect its spe- cies diversity and further exploitation. The results showed that specimen and germplasm collected include 116 species belonging to 16 genera, including seven variants. Cypert^s rotundus Linn., Cyperus iria Linn., Carex brutmea Thunb. and other 10 species distributed widely, which distribution was widespread and species richness higher. The Cyper- aceae plants were concentrated in Lianyungang, Yancheng area and Nanjing, Changzhou area, and low-altitude sec- tion. The distribution types of genera and species were dominated by the world distribution, pan tropic distribution and temperate Asia distribution, have the transition from pan tropic distribution to Temperate zone. The research may collect scientific resources, effective protection, use and provide scientific basis for the evaluation.
