摘要: 用系统整体的观点。结合乔木层郁闭度(Xl)、灌木层盖度(X2)、草本层盖度(X3)、枯落物层盖度(X4)与林地土壤侵蚀模数建立的回归模型分析,提出了多层经营的概念,即"同步经营林分的乔木层。灌木层、草本届和枯落物层,根据各层目标功能确定经营措施,获取生态经济的整体效益。使林分在高效高产水平上持续协调发展"。并通过分析马尾松低效防护林系统群落各层次的目标功能,确立了多层经营的指导思想,据此分层阐述经营技术。

Abstract: Basing on systematic theories and a linear regression of the soil erosion modulus (Y) with tree coverage (X1), shrub coverage (X2), herb coverage (X3) and litter coverage (X4) (Y=5621-4348*X1-21*X2-20*X3-3*X4, R=0.9185) the concept of the multiple-stratum management system (MSMS) was creatively defined, i.e,Simultaneousy manage the tree, shrub, herb and litter stratum respectively and apply the improvement technology according to the objective function of each stratum to achieve the best ecological and economic benefit so that tie stands can develop successively and harmoniously at high-yield and with high efficiency. According to the objective function of each stratum of the deteriorated forest community of Masson pine (Pinus massoniana), the key points of MSMS was developed and management technology of each stratum was described.

Key words: MASSON PINE, DETERIORATED FOREST, ECOSYSTEM, FOREST MANAGEMENT
