摘　　要：植物多样性对于区域生态平衡和生态功能的维护以及生物资源的可持续性有重要意义。湿地松(Pinus elliottii)是我国南方丘陵区主要的造林树种,具有显著的经济效益,且发挥着维护生态环境的重要作用。本试验对井冈山大学校园湿地松人工林的植物多样性进行研究,结果表明湿地松人工林的植物物种有37种,Margalef物种丰富度指数(12.302±1.450)与江西省吉安县湿地松人工林的物种多样性丰富度指数相近,Shannon-Wiener多样性指数(0.444±0.219)和Simpson多样性指数(0.972±0.011)均低于相同气候区湿地松人工林植物多样性指数,说明试验区湿地松人工林群落结构单一,不利于植物群落的稳定和正常生态功能的发挥。应合理配置一些阔叶树种来形成异龄混交林结构,以提高植物多样性、系统稳定性及生态系统服务功能。Plant diversity is of great significance for maintaining regional ecological balance and ecological functions and for sustainability of biological resources.As a main afforestation tree species in the hilly region in Southern China,Pinus elliottii has created significant economic benefits and plays an important role in maintaining the ecological environment.In this experiment,the plant diversity under P.elliottii plantation in Jinggangshan University was studied.The results showed that there were37species of plant in the plantation.Margalef species richness index(12.302±1.450)is close to that in P.elliottii plantations in Ji'an County,Jiangxi Province.Shannon-Wiener diversity index(0.444±0.219)and Simpson diversity index(0.972±0.011)were respectively lower than that in P.elliottii plantations in the same climate zone,which indicated that the structure of the plantation was single and is not conducive to the stability of plant communities and the development of normal ecological functions.To enhance plant diversity,system stability and ecosystem services of the plantation,some b
