The distribution patterns of dominant tree populations in Quercus variabilis plantation
摘要
Abstract
To study the spatial distribution patterns and variations of the dominant tree populations in a Quercus variabilis plantation in Lianyungang,the important values of tree species in the Quercus variabilis plantation were calculated based on the plot data,and the dominant tree species in the forest were determined.Some indexes such as David and Moore' s index,negative binomial parameter,Lloyd's index,patch index and Morisita index were applied to analyze the distribution patterns of dominant tree populations in the Quercus variabilis plantation.The results indicated that the dominant tree species of Quercus variabilis plantation included Quercus variabilis,Rhus chinensis,Dalbergia hupeana and Pinus densiflora,and these dominant tree populations appeared an aggregation distribution pattern; meanwhile,for the same tree population,the aggregation degree of populations at different age stage was significant,the aggregation strength of Quercus variabilis populations decreased as the age stage increasing,but the aggregation degree of Rhus chinensis population and Dalbergia hupeana population increased respectively as the age stage increasing.It proved that distribution patterns of the dominant tree populations in the Quercus variabilis plantation were closely related to population size,biological and ecological characteristics.Release cutting could enhance the light condition and promote the regeneration of associated tree species.关键词
