Community Structure and Natural Regeneration Characteristics of Vatica mangachapoi Forest in Shimei Bay

Abstract

Abstract: The Vatica mangachapoi forest in Shimei Bay has an important role of natural model in rehabilitation and reconstruction of coastal shelterbelt.The characteristics of community structure and natural regeneration in Shimei Bay Vatica mangachapoi forest were investigated and analyzed by using plot survey method and the results showed:overcut forest and secondary forest have obvious different features,in which the basal area and average DBH of the Vatica mangachapoi in the overcut forest were 53.98% and 19.43% higher than those in the secondary forest,but the density of the Vatica mangachapoi in the secondary forest was 17.47% higher than that in the overcut forest.The Vatica mangachapoi was the predominant species in the two kinds of forest stands,with over 95% of Vatica mangachapoi composition (basal area) and over 0.8 of the importance value.The diameter structure of Vatica mangachapoi was mainly distributed among 5～20cm diameter classes,in which most of trees are in 5～10cm diameter classes,with 74.6% and 66.1% of the total numbers separately in secondary forest and overcut forest.The natural regeneration numbers of the Vatica mangachapoi saplings in the two kinds of stands were adequate,but the numbers of seedlings in the overcut forest were inadequate,with only 1550 trees per hectare.The regeneration seedlings and saplings fit aggregated distribution,with a very high degree of aggregation.

Key words: Vatica mangachapoi, natural regeneration, Shimei Bay
