【摘要】：经文献梳理后发现,在国内外林业产业与森林生态相互关系的研究中,存在撇开两者所处的森林资源环境而孤立地就两者关系论两者关系的缺陷。为此,引入森林资源环境中介变量,运用结构化的压力-状态-影响-响应(PSIR)和定量化的结构方程模型(SEM),确定了林业产业、森林资源环境与森林生态指标及其作用路径系数,据此定量测度了其相互作用程度,并揭示了其相互作用机理。首先,基于三者理论关系分别提出了林业产业通过森林资源环境对森林生态作用的研究假设模型SM_P和森林生态通过森林资源环境对林业产业作用的研究假设模型SM_C,并构建PSIR系统结构以选取其初始指标。其次,搜集相关数据,运用SEM对初始指标筛选获得最终指标,同时分别建立林业产业通过森林资源环境对森林生态作用的实证模型SEM_P和森林生态通过森林资源环境对林业产业作用的实证模型SEM_C以验证SMP和SM_C。最后,得到三者相互作用系数,定量测度了其相互作用程度,还揭示了其相互作用机理。研究表明:(1)林业产业、森林资源环境与森林生态两两相互影响,任何变量在另两个变量相互关系中发挥着部分中介作用且直接效应强度大于间接效应强度。(2)林业产业对森林生态、森林资源环境具有主导作用。(3)中国林业产业与森林生态相互关系正由恶性循环向良性互动过渡转化。(4)就目前数据计量所言,中国要达到林业生态安全和生态文明状态,还任重道远,亟需引起高度重视。未来本成果可用于林业生态安全和生态文明评价等研究,有利于深入探讨林业产业、森林资源环境与森林生态协调共生机制。
[Abstract]:After combing the literature, it is found that, in the study of the relationship between forestry industry and forest ecology at home and abroad, there is a defect of isolating the relationship between the forest resources and the forest ecology by setting aside the forest resource environment in which the two are located. By introducing the intermediate variables of forest resources and environment, using structured pressure-state-effection-response (PSIRR) and quantitative structural equation model (SEMN), the forest industry, forest resources environment and forest ecological indexes and their action path coefficients were determined. Based on this, the degree of interaction is quantitatively measured, and the mechanism of interaction is revealed. Based on the three theoretical relationships, a hypothetical model of forest industry through forest resource environment (SM_P) and a hypothetical model of forest ecology through forest resource environment (SMCs) to forestry industry are put forward. Build the PSIR system structure to select its initial index. Secondly, Collect relevant data, use SEM to screen the initial indicators to obtain the final indicators, At the same time, the empirical models of forestry industry through forest resources and environment on forest ecology are established, respectively, SEM_P and SEM_C are established to verify SMP and SMC. Finally, the interaction coefficients of the three models are obtained. The degree of interaction is quantitatively measured, and the mechanism of interaction is also revealed. The study shows that the forestry industry, forest resources and environment and forest ecology interact with each other. Any variable plays an intermediary role in the relationship between the other two variables and the intensity of direct effect is greater than that of indirect effect. The relationship between China's forestry industry and forest ecology is changing from a vicious circle to a benign interaction. (4) according to the current data measurement, China wants to reach the state of forestry ecological security and ecological civilization. In the future, this achievement can be used in the study of forestry ecological security and ecological civilization evaluation, which is conducive to the in-depth study of forestry industry, forest resources and environment and forest ecological coordination and symbiosis mechanism.
