Volume and biomass analysis of main forest types in Luofushan Provincial Nature Reserve of Guangdong Province
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 6 042.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 m3·hm-2,the highest was the LFS-M M.chinensis-Rapanea neriifolia evergreen broda-leaved forest,which was 265.04 m3·hm-2.The average accumulation volume of the clusters of the cluster was 158.27 m3·hm-2,the highest was the P.massoniana-S.superba associationt,which was 186.33 m3·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.
