摘　　要：利用皖南山区330株马尾松样木调查数据,选用6种一元材积回归方程,拟合各模型参数,建立了马尾松材积与地径回归模型,并进行了适用性检验。结果表明,皖南山区马尾松材积与地径最佳关系模型为Y=49.4672(1-exp(-0.00706x))2.9309,相关指数(R)为0.96,总相对误差(RS)为-0.18%,符合森林资源调查精度要求。在此基础上,编制了皖南山区马尾松地径一元材积表,为该区域林政资源管理提供重要理论依据,具有十分重要的实践意义。Based on the data of 330 sample trees ofPinus massoniana in the mountainous area of southern Anhui, the volume-ground regression model of P. massoniana was built by selecting six one-dimensional volume regression equations and fitting the model parameters. The suitability of the model was tested. The results showed that the most suitable volume-ground regression model of Pinus massoniana was Y =49.4672 （ 1-exp （-0.00706x）） 2.9309 Its regression index （R） and total relative error （RS） were 0.96 and -0.18%, respectively, which meet the requirement of forest resources survey precision. The one-dimensional ground diameter volume table complied for P. massoniana in the mountainous area of southern Anhui can provide an important theoretical basis for forest resource management in this area and has very important practical significance.
