福州市主要公园乔木树种多样性分析

对福州市4个主要公园的乔木种类和各树种的个体数量进行调查,采用α多样性指数对各个公园乔木树种的调查结果进行分析,并应用二元属性数据的β多样性指数对各个公园乔木树种的多样性进行了初步研究。结果表明:4个公园内有乔木树种共196种,隶属54科97属;Simpson生态优势度指数表现为:闽江公园北园>闽江公园南园>温泉公园>西湖公园;Shannon-Wiener多样性指数表现为:闽江公园北园>温泉公园>闽江公园南园>西湖公园;Pielou均匀度指数表现为:闽江公园南园>闽江公园北园>温泉公园>西湖公园;Whittaker多样性指数表现为:温泉公园>闽江公园北园>西湖公园>闽江公园南园;Sorenson相似度指数表现为:闽江公园南园和温泉公园的Sorenson相似度指数最小,为0.39535,闽江公园北园和闽江公园南园最大,为0.63514。
