从气候变化的概念界定、成因、影响以及林业在应对气候变化领域占据的重要地位入手,以系统理论为基础,着重分析了林业应对气候变化的作用机理,指出应对气候变化背景下的各种林业活动存在着耦合与协同关系,共同构成一个复合系统,该系统同时又是一个典型的耗散系统,存在着熵增的自发趋势。选择合理的系统结构和有效的管理模式,对系统进行内外部关系协调管理,增强负熵持续流入,抵消系统正熵产生,可使系统始终处于有序的耗散结构状态、不断进化。林业应对气候变化的管理机制主要包括运行机制、动力机制和约束机制。林业碳增加、碳贮存和碳替代是主要的运行机制,这三种运行机制共同耦合成一个复合系统。准确把握三种运行机制的作用关系,并在此基础上通过各种动力机制和约束机制不断对三种运行机制构成的复合系统输入负熵流,可以促使其走向耦合、协同共生,表现出协同进化的发展趋势。
Beginning with the definition of climate change, its causes, its influence and the important position of forestry in the field of coping with climate change, based on systematic theory, this paper focuses on the mechanism of forestry’s response to climate change and points out that all kinds of forestry under the background of climate change Activities exist coupling and collaborative relations, together constitute a composite system, which is also a typical dissipative system, there is a spontaneous trend of entropy increases. Choosing a reasonable system structure and an effective management mode can coordinate the management of the internal and external relations of the system, enhance the continuous inflow of negative entropy and offset the positive entropy generation of the system, so that the system is always in an orderly dissipative structure and evolves continuously. The management mechanism of forestry to deal with climate change mainly includes operation mechanism, motive force mechanism and restraint mechanism. The increase of forestry carbon, carbon storage and carbon substitution are the main operating mechanisms, and the three operating mechanisms are jointly coupled into a complex system. Accurately grasp the operational relationship between the three kinds of operating mechanism, and on this basis, through a variety of dynamic mechanisms and restraint mechanisms continue to enter the negative entropy flow of the composite system composed of three operating mechanisms can promote its coupling, symbiotic symbiosis, showing synergy Evolutionary trends.
