基于能值分析的闽台农业经济系统的相图法比较研究

摘要

运用能值方法,分析了福建和台湾两省农业生态经济系统发展过程中资源利用结构变化情况,以及该变化对各地环境和系统发展的影响.运用相图分析法对系统的发展进程、现状和变化趋势进行了全面系统的比较研究.结果表明,地区经济发展水平较高的台湾,农业生产过程对不可更新反馈能值的依赖更强,所造成的环境压力和对系统可持续性的削弱程度更大.针对存在的问题,提出了加强投资合作、改变传统农业生产模式、加强闽台农业生物科技合作等对策.%Energy analysis method was used to analyze the resource utilization structure changes in developing process of Fujian and Taiwan agricultural ecosystems, and the effects to local environment and system development. Then, ternary diagram analysis was used in the comprehensively and systematically comparative study of the system development process, status and trends. The results showed that, in the developed Taiwan Province, the agricultural production process relied more on the nonrenewable feedback emergy, and caused greater environmental stress and sustainability extinction of the system. Therefore, it was a wise choice to strengthen cooperation between Fujian and Taiwan agricultural -ystem to achieve sustainable development.
