摘要
设样方调查了广东天井山铜桥原生阔叶林、天群次生阔叶林和杉木人工林等 3种森林群落的植物多样性、土壤理化性质和土壤持水性能。初步结果显示 ,天群次生阔叶林的植物种类丰富 ,多样性指数高 ,土壤有机质、全氮、全磷、全钾和有效氮含量高 ,土壤持水性能较好 ;铜桥原生阔叶林的物种丰富程度稍低于天群次生阔叶林 ,但土壤速效磷和速效钾则较高 ,土壤持水性能稍弱 ;杉木人工林林分组成最简单 ,物种多样性指数最低 。
The tree diversity, soil fertility, and soil water storage capacity of three stands of forest communities on Tian jing shan were surveyed in May 2001.The preliminary result showed that all of the three indexs varied greatly with the stands. In general, Tian qun secondary broad leaved forest community possessed highest floristic diversity, soil fertility, and quantity of non capillary porosity, but lower contents of available phosphorus and available potassium. Compared with Tian quns community, Tong qiao intact broad-leaved forest was lower in tree diversity, soil fertility, but higher in the contents of available phosphorus and available potassium. The plantation of Cunninghamia lanceolata was the lowest in floristic diversity and soil fertility, and poorest in soil water storage capillary.\;
