【摘要】 本研究以湖南中部地区马尾松人工林为例,编制其不同立地条件下的碳储量生长过程表,编制马尾松林分碳储量密度控制图,探讨编制碳储量生长过程表和密度控制图所需的数据、模型和方法,并通过经营数表分析立地条件、林分年龄、林分密度以及混交林对林分碳储量的影响,提出碳汇林经营措施的建议,为以碳储量为经营目标的森林经营管理提供理论和方法依据。通过研究中所编制的马尾松碳储量生长过程表及密度控制图可以发现,相同年龄的马尾松人工林的林分碳储量随立地条件的提高而增加,即立地条件越好,碳储量越大。相同立地条件的马尾松人工林的林分碳储量随年龄的增大而增加,林分碳储量的平均生长量与连年生长量呈现先增大后减小的过程,这表明林分碳储量的增长过程并不是一成不变,在达到一定年龄后,其增长的幅度随年龄的增长逐渐减少。林分密度变化的对马尾松人工林碳储量的影响存在密度效应,即随着林分密度的增加,林分碳储量也增大,而当林分密度达到一定程度后,林分碳储量随林分密度增加的幅度逐渐减少,直至林分碳储量稳定在一定水平上。研究中还发现,选取适当的树种与马尾松进行混交,能够更加有效利用空间结构,提高林分生产力,从而使得林分碳储量高于马尾松纯林的林分碳储量。更多还原

【Abstract】 The research adopts the common counting method of forest carbon storage used in both domestic and international research, and uses the Pinus massoniana plantation in middlearea of Hunan province as the research target to organize management statistics and tables to analyze the change of carbon storage under different sites, different ages and different forest density, explores the data and models needed in the organization progress. then drew the Pinus massoniana carbon storage control figure, and discusses the choices of management measures under different influence factors, expecting to give theory accordance to the management of carbon storage.The management figures and tables show that, under the same age, carbon storage of Pinus massoniana rises with the increscent of site condition, which means more carbon storage under better site condition. Under the same site condition, the carbon storage of Pinus massoniana increase with the ages, but the average increase and annual increase undergo a period of raise and decrease, which means the increase progress of carbon storage is not constant, after a certain age, the range of increase falls with the ages. And under different forest density, there is the density effect, which shows that at the first time the carbon storage increase with the rise of density, but after a certain density, the carbon storage maintains a certain level with the rise of density. And the research also found that mixed up with property species, the space will be used effectively, and lead to the results that the carbon storage increase.更多还原
