摘要:
 以闽北建阳引种的邓恩桉为研究对象，以杉木和马尾松林分作为对比，计算了群落多样性指数、均匀度指数、优势度指数和丰富度指数，研究在福建北部建阳市引种邓恩桉对林下植物多样性的影响。结果表明，邓恩桉人工林林下共有植物种19种，高于其他3种林分；多样性指数较高的是邓恩桉-杉木混交林和邓恩桉纯林，分别为0.756和0.668；优势度指数较大的是杉木和马尾松，分别为1.000和0.907；均匀度指数较大的是邓恩桉-杉木混交林，为0.267；丰富度指数邓恩桉最大，为3.909。可见在福建建阳引种邓恩桉不会造成林下植物多样性的减少。
Abstract:
 Taking Eucalyptus dunnii which was introduced to Jianyang, northern Fujian as research object, the influences of E. dunnii on the species diversity of understory plants were examined. Cunninghamia lanceolata and Pinus massoniana stands were used as the controls. The community Shannon-Wiener index, Pielou index, Simpson index and Margalef index were calculated. Nineteen plant species were found under E. dunnii stand, higher than other 3 stands. The higher Shannon-Wiener indices were found in mixed stands of E. dunnii-C. lanceolat (0.756) and pure E. dunnii stand (0.668). High Simpson indices were found in the stands of C. lanceolata (1.00) and P. massoniana (0.907). The Pielou index of E. dunnii-C. lanceolata mixed stand was 0.267. The highest Margalef index was found in E. dunnii stand (3.909). It was concluded the that the introduction of E. dunnii did not decrease the species diversity in Jianyang.
