基于耗散结构、熵以及耦合度等理论的基础上,建立分析沙化土地封禁保护区经济社会系统与生态系统的耦合模型。得出以下结论:一是封禁保护区是典型的耗散结构,需要不断地与外界进行物质、能量和信息的交换,理想的状态是建立经济社会与生态环境互为负熵的运行机制;二是可以运用“保护区—经济社会”复合系统耦合模型,进一步监测沙化土地封禁保护区的社会经济效益。 Based on the theories of dissipative structure, entropy and coupling degree, a coupling model of economic and social systems and ecosystems in desertification protected areas was set up. The following conclusions are drawn: First, the protected area of ​​the ban is a typical dissipative structure, which needs to constantly exchange material, energy and information with the outside world. The ideal state is to establish a mechanism of negative entropy between the economy, society and the ecological environment. It is possible to use the coupled system of “protected areas - economy and society” to further monitor the social and economic benefits of desertification protected areas.
