采用现场踏查和样地调查相结合的方法，通过多次对江苏野生苔草属（ Carex）植物资源实地调查以达到对植物资源和植物多样性保护的目的。结果表明：共记录到江苏省野生苔草属植物资源45种，占全国苔草属植物种数的9％；北亚热带常绿落叶阔叶混交林分布的苔草属植物最多，占物种总数的68．89％，这与苔草属植物的生境密切相关；苔草属植物主要集中分布在低海拔段，相邻海拔段苔草属植物相似性系数较高；主要苔草属植物群落的物种多样性指数变化和均匀度指数、物种丰富度指数变化呈正相关，和优势度指数变化呈负相关。

By a combination method of field investigation and sampling investigation , we investigated the Carex plant resources in Jiangsu Province with several field surveys to protect the diversity of plants .The specimen and germplasm collected 45 spe-cies, accounting for 9%of national Carex plants.The Carex plants of north subtropical evergreen and deciduous broad-leaved forest were the largest species , accounting for 68.89%of the total, which was closely related with the habitat of Carex plants.The plants of Carex were mainly concentrated in the low-altitude section, and the similarity coefficient of ad-jacent altitudinal was higher .By analyzing the species diversity of 13 main Carex plant communities , the change of Shan-non-Wiener species diversity index , Patrick evenness index and Pielou richness index were positive correlation , Shannon-Wiener species diversity index and Simpson the dominance index were negative correlation .The Shannon-Wiener and Simp-son species diversity index showed a same change trend calculated based on the number , coverage and biomass .
