摘　　要：“森林矢量标准地/标准木调查技术”是完成森林生态补偿的一项重要指标依据。为了对森林生态补偿指标标准化,通过数据调查精度控制、数据结构格式统一、数据库完整性核查等控制手段,构建了鲁中南山地丘陵区分区数据库,并分析了18个优势树种DBH(胸径)和树高相关性。研究区域18个优势树种总株数为23910株,其中欧美杨(Populus nigra)、侧柏(Platycladus orientalis(L.)Franco)、毛白杨(Populus tomentosa)、刺槐(Robinia pseudoacacia)、白蜡(Fraxinus chinensis Roxb.)、悬铃木(Platanus orientalis)、黑松(Pinus thunbergii Parl.)、银杏(Ginkgo biloba L.)、赤松(Pinus densiflora Sieb.et Zucc.)和国槐(Sophora japonica L.)10个优势树种株数较多,每个树种的株数均大于300株,总株数共计23089株,约占优势树种总株数的96.57%。18个优势树种的平均每公顷蓄积在51.0~140.6 m 3之间,差别较大。通过分析发现:麻栎(Quercus acutissima Carruth.)、欧美杨、银杏、油松(Pinus tabuliformis Carr.)4个优势树种胸径和树高相关性较强,相关系数(R 2)均大于0.5,麻栎的相关性最强,为0.5391,欧美杨、油松和银杏的相关系数分别为0.5255、0.5230和0.5215,其他14个优势树种胸径和树高相关性均较低。该工作能够为鲁中南山地丘陵地区森林资源调查监测工作提供基础数据支撑,为该区域科学开展森林生态系统保护修复、监督管理等提供决策支撑。"The survey technology of forest vector sample plot/sample tree"serves as a crucial indicator for accomplishing forest ecological compensation.In order to standardize the indicator of forest ecological compensation,this paper established a regional database of mountainous and hilly areas in south-central Shandong Province by means of data survey precision control,data structure format unification and database integrity verification,and analyzed the correlation between DBH(diameter at breast height)and tree height of 18 dominant tree species.There were 23910 trees belonged to 18 dominant tree species in the study area.Among them,the top ten dominant tree species were Populus nigra,Platycladus orientalis(L.)Franco,Populus tomentosa,Robiniapseudoacacia,Fraxinus chinensis Roxb.,Platanus orientalis,Pinus thunbergii Parl.,Ginkgo biloba L.,Pinus densiflora Sieb.et Zucc.and Sophora japonica,which the amounts of each species were more than 300 and the total amount was 23089,that accounting for about 96.57%of the total number of all dominant tree species.The sand volume per hectare of 18 dominant tree species ranged from 51.0 to 140.6 m 3,with great difference.Through analysis,there was a strong correlation between DBH and tree height of four dominant tree species,including Quercus acutissima Carruth.,P.nigra,G.biloba L.and Pinus tabuliformis Carr.,and the correlation coefficients(R 2)were all greater than 0.5.Among them,Q.acutissima Carruth.had the strongest correlation of 0.5391.The correlation coefficients of P.nigra,P.tabuliformis Carr.and G.biloba L.were 0.5255,0.5230 and 0.5215,respectively.The correlation between DBH and height of other 14 dominant tree species was low.This work provided basic data support for forest resources investigation and monitoring in mountainous and hilly areas in south-central Shandong Province,and also offered decision-making support for scientific forest ecosystem protection and restoration,supervision and management in this region.
