采用样方取样法调查了广东省始兴县罗坝镇小安村的小红栲林.根据1400m2的样方面积调查,测算了群落乔木层、灌木层、草本层和层间植物的重要值、物种多样性指数(Shannon-Wiener指数)、物种均匀度、生态优势度.结果表明,群落中乔木层、灌木层、草本层和层间植物的物种多样性指数(Shannon-Wiener指数)分别为2.0248、2.9021、2.093和2.2698;物种均匀度分别为0.3916、0.5491、0.6051和0.7566;生态优势度分别为0.3946、0.1503、0.2171和0.2415.本研究可为小红栲的生产经营提供依据.
Sampling method was used to investigate the small red tress forest of Xiaoan Village, Luoba Town, Shixing County, Guangdong Province. According to the plot area of 1400 m2, the importance value, species diversity index (Shannon-Wiener index), species evenness and ecological dominance of the community tree layer, shrub layer, herb layer and interlaminar plant were calculated. The results showed that the Shannon-Wiener index of tree layer, shrub layer, herb layer and interlaminar plant in the community were 2.0248, 2.9021, 2.093 and 2.2698, respectively. The evenness of species was 0.3916 and 0.5491 , 0.6051 and 0.7566, respectively. The ecological dominance was 0.3946, 0.1503, 0.2171 and 0.2415 respectively. This study can provide the basis for the production and management of Little Red Clover.
