林业产业与森林生态系统耦合度测度研究

Measurement Study on System Coupling between Forestry and Forest Ecosystems

基于复杂系统理论,分析了林业产业与森林生态系统之间的相关性及耦合特征,阐述了耦合系统和系统耦合度概念及测度方法的选择依据。运用灰色关联度评价模型,采用斜率关联度计算方法,建立了林业产业与森林生态系统的耦合度模型。以伊春市双丰林业局林业产业为例,结合该局的实际情况,构建了关于林业系统耦合度的评价指标体系,并用调研数据验证了模型和评价指标体系的有效性和合理性。结果显示,该地区的林业产业与森林生态系统间的耦合度为0.47,耦合关系中等,相互影响的程度一般。最后,基于耦合度测算结果给出了林业产业发展对策建议。

In order to get the coordinated and sustainable development in the forestry industry and forest ecosystem, based on the theory of complex system, analyze the correlations and coupling feature between forestry industry and forest ecosys- tem, elaborate the concepts of coupling system and the degree of systemic couphng as well as the foundation of measure- ment selected. Build the coupled degree model of forestry industry and forest ecosystem by the application of gray correla- tion degree evaluation model and using the calculation of the slope correlation degree. Furthermore, take the Shuangfeng Forestry in City Yichun as an example to construct the evaluation indicator system of the coupled degree of forestry sys- tem with local specific circumstances, and test it available and reasonable. The result shows that the couple degree is 0. 47, the region~ coupled relation between forestry industry and forest ecosystem is medium and the degree of interaction in general. Finally, give some advices of forestry industry development in terms of the result of measurement.
