A New Distribution Record of Gleditsia in Guizhou and Its Community Characteristics
摘要
Abstract
Through field surveys and specimen identification,a new distribution record for a Gleditsia spe-cies in Guizhou was established,namely Gleditsia australis.To further understand the characteristics of the com-munity where G.australis is found,and to make full use of and protect the resources of the Gleditsia genus,three 20 m × 20 m plots were established in Liping County and Tianzhu County for community investigation.The spe-cies composition,life forms,community structure,and plant diversity of the communities were analyzed.The res-ults showed that G.australis represents a new distribution record for Gleditsia species in Guizhou,occurring in Liping County,Tianzhu County,and Libo County.The three communities contain 49 families,83 genera,and 103 species of vascular plants.Community Ⅰ has 21 families,27 genera,and 29 species;community Ⅱ has 26 families,36 genera,and 39 species;community Ⅲ has 34 families,48 genera,and 56 species.There were obvious differ-ences among families,genera and species.The community is dominated by small-sized,high-bud plants and dwarf high-bud plants,exhibiting typical characteristics of the subtropical Central Asian region.The community has a distinct stratification,which can be divided vertically into the tree,shrub,and herbaceous layers.The aver-age diameter at breast height(DBH)of community Ⅲ is 9.1 cm,and its diameter class structure follows an"inver-ted J-shape"with a lack of larger diameter individuals but good regeneration.Communities Ⅰ and Ⅱ have similar diameter class ranges,and their successional stages are more advanced.关键词
