Community Characteristics and Species of Wild Populations in Alpinia oxyphylla
In order to understand the distribution,habitat,community characteristics and the species,protect and utilize the wild resources sustainably in the future,methods of field investigation,specimen collection and classification identification were used to investigate community of wild populations in A.oxyphylla.The results showed that there are 104 species,which belong to 94 genera,53 families.There are 9 families,10 genera and 12 species in pteridophytes,1 families,1 genera and 1 species in gymnosperms,and 43 families,83 genera and 91 species in angiosperm.There are more species in the two dominant families,Compositae and Euphorbiaceae.There are 8 alien invasive plant species in the communities,which accounted for 7.69％ of the total species.Among the 4 sampling areas,A.oxyphylla are all the dominant species and its important values were all the biggest in the communities.The coverage are significantly different:Qiongzhong＞ (Lingshui,Wanning),Baoting＞ (Lingshui,Wanning),and there are no significant difference between other sampling areas.The height are significantly different:Baoting ＞ (Lingshui,Wanning),Qiongzhong ＞ (Lingshui,Wanning),and there are no significant difference between other sampling areas.There are no significant difference in density among the sampling areas.There are significant negative correlation between the coverage and soil temperature,significant negative correlation between the density and soil temperature,while significant positive correlation between the height and soil moisture,significant negative correlation between the height and the soil pH,soil temperature.There is no correlation between the important values of A.oxyphylla and the soil factors.
