| 摘 要： 分析了广东汕头海区南澳岛的典型退化草坡的群落结构．结果表明，该群落有高等植物２９种，可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，Ｓｈａｎｎｏｎ－Ｗｅｉｎｅｒ多样性指数为１．５９，群落的叶面积指数为１．５３，生物量为４．８１ｔ•ｈｍ－２．另外，还比较了退化草坡与同岛的人工林和大陆的退化草坡的群落结构，提出了退化草坡的改造利用方式． |
| 关 键 字(英文)：community stucture degraded grassland Nanao island of Guangdong |
| 摘 要(英文)：The community structure of a degraded grassland in Nanao island, Guangdong, China, is investigated. The results show that the community is composed of shrub layer and herb layer. There are 29 species in the community, most of them are tropical and subtropical species and nanophanerophyte and microphylls types. The Shannon Weiner diversity index, leaf area index and the biomass of the community are 1 59,1 53 and 4 81 t•hm -2 ,respectively. The community structure is the result of long term influence of storms, erosion of soil and human disturbance. In addition, the community structure of the degraded grassland is compared with that of the plantations in the island and a gegraded grassland in mainland. Furthermore, the utilization of the community is discussed. |
