Abstract

Abstract: Eleven sample plots from major mountain areas,such as Taishan,Mengshan,and Kunyushan,were selected in Shandong Province to evaluate the growth and renewal of the communities of Pinus taeda and Larix kaempferi.The following three aspects were investigated to determine the adaptability of P.taeda and L.kaempferi in Shandong Province:the population characteristics,the community composition,and the species diversity.The results showed that the species numbers of trees,shrubs,and herbs were 15 species,29 species,and 27 species in the P.taeda community and 26 species,49 species,and 49 species in the L.kaempferi community,respectively.The plant densities of trees,shrubs,and herbs for the P.taeda community were(15.38±1.84)/dam²,(51.50±13.00)/dam²,(14.38±3.80)/m²,and for the L.kaempferi community were(10.55±0.97)/dam²,(37.07±7.99)/dam²,(25.45±11.35)/m².In the P.taeda community,the population of the P.taeda was the stable type,the Quercus variabilis was the significant growth type,the Q.acutissima and the P.densiflora were the growth type.In the L.kaempferi community,the population of the L.kaempferi,Sorbus pohuashanensis,Tilia tuan were the stable type,and the Q.variabilis was the significant growth type.The richness indexes and Shannon-Wiener diversity indexes of the P.taeda community were shrub>herb>tree,Simpson diversity indexes and Pielou evenness indexs were herb>shrub>tree.The richness indexes of the L.kaempferi community was shrub>herb>tree,Shannon-Wiener diversity indexes and Simpson diversity indexes were shrub>tree>herb,Pielou evenness indexs was herb>shrub>tree.The succession tendency of the P.taeda community was P.taeda forest→theropencedrymion→Q.variabilis forest or Q.acutissima forest,and the L.kaempferi community was L.kaempferi forest→theropencedrymion→Q.variabilis forest or mixed forest.
