摘要
通过样方调查法,对广东罗浮山省级自然保护区主要森林类型的蓄积量与生物量进行调查,分析其蓄积量与生物量的分布特点,为森林资源的保护和调查监测提供科学依据。结果表明:在16个20 m×20 m的样方中,共记录有维管植物210种,隶属于81科158属。监测样地乔木层植物种类121种,隶属于48科90属,灌木层植物种类109种,隶属于42科78属,草本层植物种类29种,隶属于19科28属,层间藤本植物种类40种,隶属于21科33属,各类植物个体总数为6042个。监测样地可划分为3个植被型,5个植被亚型,5个群丛。监测样地乔木层单一树种华润楠、木荷、马尾松和黄樟的蓄积量排在前4。监测样地乔木层平均蓄积量为161.32 m^(3)·hm^(-2),最高的是LFS-M华润楠-密花树常绿阔叶林,为265.04 m^(3)·hm^(-2);群丛乔木层平均蓄积量为158.27 m^(3)·hm^(-2),最高的是马尾松-木荷群丛,为186.33 m^(3)·hm^(-2)。由D方程和D2H方程得出不同监测样地乔木层生物量均为LFS-M华润楠-密花树常绿阔叶林的最高。由D方程得出不同群丛乔木层生物量为华润楠-密花树群丛的最高,达174.20 t·hm^(-2);由D2H方程计算得出群丛乔木层生物量为马尾松-木荷群丛的最高,为154.10 t·hm^(-2)。
The biomass and volume of main forest type of Luofu shan Provincial Nature Reserve were studied by the method of quadrat survey,analyze the distribution characteristics of its accumulation and biomass.to provide scientific basis for the protection and survey of forest resources.The results showed that:a total of 210 species of vascular plants belonging to 81 families and 158 genera were recorded in the 16 plots of 20 m×20 m.There were 121 vascular plants belonging to 48 families and 90 genera were recorded in the tree layer.109 vascular plants belonging to 42 families and 78 genera were recorded in the shrub layer.29 vascular plants belonging to 19 families and 28 genera were recorded in the herbal layer.40 species of vascular plants belonging to 21 families and 33 genera were recorded in the rattan layer.The total number of various types of plant individuals is 6042.The monitoring sample can be divided into 3 vegetation types,5 vegetation subtypes,and 5 associations.The accumulation volume of Machilus chinensis,Schima superba,Pinus massoniana,and Camphora parthenoxylon in monitoring were ranked among the top 4.The average accumulation of the monitoring was 161.32 m^(3)·hm^(-2),the highest was the LFS-M M.chinensis-Rapanea neriifolia evergreen broda-leaved forest,which was 265.04 m^(3)·hm^(-2).The average accumulation volume of the clusters of the cluster was 158.27 m^(3)·hm^(-2),the highest was the P.massoniana-S.superba associationt,which was 186.33 m^(3)·hm^(-2).The D equation and D2H equation indicated that the biomass of the tree layer in various areas was LFS-M M.chinensis-R.neriifolia evergreen broda-leaved forest,which was the highest.According to the D equation,the biomass of group tree layers was the highest in the M.chinensis-R.neriifolia association,reaching 174.20 t·hm^(-2).According to the D2H equation,the biomass of the P.massoniana-S.superba association was the highest,at 154.10 t·hm^(-2).
