摘　　要：对"永林公司"经营区不同森林经营模式物种多样性特征进行了比较研究。结果表明:在经营区内有植物222种,属于113属和72科。9种不同经营模式中不同生长型物种的丰富度存在着比较明显的差异,以灌木层物种丰富度最高,乔木层次之,而以草本层最低;不同经营模式的物种多样性基本表现为灌木层>乔木层>草本层。物种多样性指数和丰富度指数存在着密切的正相关。综合分析表明,块状利用模式的物种多样性最高,改良增效模式其次,而定向培育模式和保育补植模式的物种多样性最差,这也表明天然林的物种多样性比较好,人工林的物种多样性较差的一般规律。The species diversity in different forest management models in Fujian Yong＇an Forestry （Group） Joint-stock Co. ,Ltd were studied. There were 222 species,ll3 genus and 72 families in the management area. The richness of species in 9 management models varied slightly with different growth forms. The richness of the shrub species was the highest, arbor was the second and the herb was the lowest. The spe- cies diversity under different models generally displayed as shrub layer〉arbor〉herb. The species diversi- ty and richness index were closely positive-correlative. By comprehensive analysis, species diversity of ＂ block utilization＂ model was the highest, ＂modification to enhance efficiency＂ model was the second, ＂the set-directed tending＂ and ＂replanting＂ models were the worst, which demonstrated that the species diversi- ty of natural forests was relatively high, while that of plantations was relatively low.
