Study on the Species Diversity of Undergrowth Plant of Cunninghamia lanceolata Pure Forest and Mixed Forest with Broadleaved Trees in Northern Fujian

Abstract

Abstract: In this paper,the undergrowth plant diversity of Cunninghamia lanceolata pure forest,and its three types of mixed forest with 3 species of broadleaved trees in Jian’ou,Fujian province were studied. The results showed that the abundance and Shannon-wienner indexes in all three types of mixed forests were described as shrub layer >herbaceous layer. Except that of Cunninghamia lanceolata×Liriodendron chinense,the Simpson indexes of the 2 other types of mixed forest were greater in the herbaceous layers than that of the shrub layers,Pielou indexes were greater in the shrub layers than the herb layers. The undergrowth plant species of mixed forest was smaller,the dominant species were obvious,and the distribution was uneven. The distinction of four kinds of diversity indexes measured in the different mixed forests was not obvious. Compared with the mixed forest,the difference of all indexes in the pure forest were not significant. The results would help to improve the cultivation and management of Cunninghamia lanceolata and its mixed forest in northern Fujian province,and eventually realize the sustainable management of the Cunninghamia lanceolata forest.

Key words: Cunninghamia lancelata, pure forest, mixed forest, undergrowth plant, species diversity
