摘要:
应用植被样方调查法,对地处粤北山区的连州田心、乐昌八宝山、曲江罗坑、仁化范子山、始兴刘张家山、平远龙文-黄田等自然保护区的森林植被优势种进行比较分析,并用极点排序法对上述6地的森林群落进行二维排序。结果表明:各地共有优势种仅有红楠和枫香2种,且优势度差异明显。各地群落的相似性系数以田心与龙文-黄田之间的65.49%为最大;八宝山与其它各地的群落相似性程度均小于50%。群落相似性系数与极点排序结果均提示森林群落的相似性程度受土壤基质、海拔高度的影响要大于经纬度和地理距离的影响。各地森林群落间接地反映了它们的生境条件,对保护区森林群落的比较研究,可为今后广东自然保护区的网络建设提供参考。
Abstract:
By using the vegetation quardat method,the dominant families and species of the forest vegetation in Tianxin of Lianzhou City,Babaoshan of Lechang City,Luokeng of Qujiang County,Fanzishan of Renhua County,Liuzhangjiashan of Shixing County,and LongwenHuangtian of Pingyuan County in the mountain regions of Guangdong Province,China,are compared. The twodimension sort of six forest communities is also compared by using the polar ordination method in this paper. The results show that the common dominant species are Machilus thunbergii and Liquidambar formosana,and their dominances are different from each plot site. The biggest similarity coefficient of community is 65.49% between Tianxin and LongwenHuangtian;while the similarity coefficients are low than 50% between Babaoshan and other sites. The result suggests that the similarity of forest community is mainly rely on the soil character,latitude,and altitude which is apparently much important than that of geologic distance. The forest community in different sites can reflect their conditions of habitats. The comparison study of forest communities in nature reserves can also provide some suggestions for the net construction of nature reserves in Guangdong province.
