中文摘要:
      对于具有耦合关系的流域复杂系统,从演化过程、驱动机制和政策效应等方面分析生态-农业耦合效应,是实现流域生态文明的方法论。论文采用系统耦合测度模型,对洱海流域系统耦合度及动态耦合过程进行分析,揭示流域生态文明下洱海流域生态农业政策的效应。结果表明:①生态农业措施对洱海流域生态-农业系统协调耦合产生积极作用。②1994-2015年,洱海流域生态-农业系统耦合度由0.48提升到0.75,接近0.8的协调耦合阈值,表明生态-农业系统由磨合阶段进入高水平耦合阶段。③耦合态势可分为磨合消耗、快速消耗、快速协调与磨合协调四个阶段,既揭示了初期生态农业政策的短期效益,又预示出中远期流域农业面源污染治理的困境。
英文摘要:
      As basin complex system coupling relationship,analysis of Ecological - Agriculture coupling effect by Evolutionary process, the drive mechanism and policy effects is to achieve ecological civilization basin methodology. We analyzed the degree of coupling Erhai Lake Basin system and dynamic coupling process ,by the system coupling measure model,reveal effects of ecological agriculture policy Erhai Lake Basin Watershed Ecological Civilization. The results showed that: ①Ecological agriculture measures on Erhai Lake Basin Eco - coordination of agricultural systems have a positive effect coupling. ②1994-2002, ecological Erhai Basin - agricultural systems to enhance the degree of coupling from 0.48 to 0.75, close to the 0.8 threshold coupling coordination, suggesting eco - agriculture system by running-in phase to the high level of coupling phase. ③Coupled situation can be divided into run-consumption, rapid consumption, rapid,coordinated and run-coordinated four stages, both reveal the initial short-term benefits of ecological agriculture policy, but also indicates that the plight of the long-term watershed agricultural nonpoint source pollution control.
