风景名胜区和自然保护区乌冈栎群落特征

为了进行乌冈栎生存状况评价并提出相应的保护策略,在瑞云山风景名胜区、桃源洞风景名胜区、邵武将石省级自然保护区和南平茫荡山省级自然保护区,用立木级结构代替年龄结构、重要值、物种多样性、群落相似性系数等指标对乌冈栎群落特征进行研究。结果表明：在4个研究区,乌冈栎均属于衰退型种群,瑞云山和桃源洞风景名胜区的赤楠种群将替代乌冈种群,种群衰退趋势明显;瑞云山风景名胜区和邵武将石省级自然保护区乌冈栎群落优势种显著,物种组成也丰富,而桃源洞风景名胜区和南平茫荡山省级自然保护区乌冈栎群落优势种显著,但物种组成少;在4个研究区之间的乔木层和草本层,Shannon-Wiener指数变幅较大,而Pielou均匀度指数乔木层、灌木层和草本层变幅均不大;瑞云山风景名胜区与桃源洞风景名胜区、邵武将石省级自然保护区与南平茫荡山省级自然保护区群落相似性系数均很大,其中,瑞云山风景名胜区与邵武将石省级自然保护区的群落相似性系数最大（0.65）。

Comparative study on community characteristics of Quercus phillyraerides A.Gray between scenic spot and nature reserve

In order to evaluate the living conditions and propose the protection strategy of Quercus phillyraerides A.Gray communities,the characteristics of Quercus phillyraerides A.Gray communities by standing tree size structure used in place of age structure,important values,the majority of species,community similarity in Ruiyen Mountain Scenic Spot,Taoyuan Hole Scenic Spot,Shaowu Jiangshi Provincial Nature Reserve and Nanping Mangdang Mountain Provincial Nature Reserve are analyzed.The results show that: in Ruiyen Mountain Scenic Spot,Taoyuan Hole Scenic Spot,Shaowu Jiangshi Provincial Nature Reserve and Nanping Mangdang Mountain Provincial Nature Reserve,the Quercus phillyraerides A.Gray communities belong to a recession-type stocks,the Syzygium buxifolium Hook et ARnpopulation will replace the Quercus phillyraerides A.Gray population declining significantly in Ruiyen Mountain Scenic Spot and Taoyuan Hole Scenic Spot.The dominant species and species composition are rich in Ruiyen Mountain Scenic Spot and Shaowu Jiangshi Provincial Nature Reserve;the dominant species is rich in Taoyuan Hole Scenic Spot and Mountain Provincial Nature Reserve,however,fewer species composition.The Luffing of Shannon-Wiener index is high between the tree layer and herb layer,while Pielou evenness index of tree layer,shrub layer and herb layer is similar.The communiy similarity is great between Ruiyen Mountain Scenic Spot and Taoyuan Hole Scenic Spot,Shaowu Jiangshi Provincial Nature Reserve,Nanping Mangdang Mountain Provincial Nature Reserve,which has the largest similarity coefficient(0.65) between Ruiyen Mountain Scenic Spot and Shaowu Jiangshi Provincial Nature Reserve.
