摘　　要：分析了广东鹤山草坡的群落结构。结果表明 ,该群落有高等植物 18种 ,分为灌木层和草本层 2个层次 ,以矮高位芽、小型叶植物为主 ,种类以热带 -亚热带分布种为主 ,Shanon Weiner多样性指数为 1 2 5,群落的叶面积指数为 2 2 8,生物量为 15 2 2t/hm2 。比较了大陆退化草坡、海岛退化草坡和当地的人工林的群落结构 。The community structure of a degraded grassland in Heshan City, Guangdong, China, is investigated. The results show that the community is composed of shrub layer and herb layer. there are 18 species in the community, most of them are tropical and subtropical species and nanopherophyte and microphylls types.The Shannon\|Weiner diversity index, leaf area index and the biomass of the community are 1 25,2 28 and 15 22 t/hm\+2,respectively. The community structure is the result of long\|term human disturbance. In addition,the community structure of the degraded grassland is compared with that of the plantations in the city and a degraded grassland in island. Furthermore, the utilization of the community is discussed.
