Evolutionary game of stakeholders’ behavioral strategies in wetland ecosystems from the vulnerability perspective

Wetland ecosystems have been seriously degraded by human activities and natural factors, and its restoration and coordinated development depend on long-term effective cooperation between the government and investors and providers. From the perspective of vulnerability of wetland ecosystem construction, this paper takes the government and investors, providers as the research object and propose a wetland ecosystem cooperation network, the article considers the “Matthew effect” of network connection and relationship cost, and uses the method of the evolutionary game on complex networks to construct the cooperative game model of wetland ecosystems. This research finds that (1) the vulnerability of wetland ecosystem varies greatly in different development stages, especially when the government subsidy coefficient for providers is reduced to 0.3, the vulnerability index is instead smaller.
