Abstract
The assessment of ecological environment during the large-scale development of islands is a major topic in the study of current coastal islands. Choosing the appropriate assessment method to evaluate the suitability of carrying capacity of islands and making relevant suggestions are significant to the sustainable development of islands. Ecological footprint method is used to analyze the ecological carrying capacity of Pingtan Island (PI) from 2005 to 2016 for promoting the coordinated rational development and construction and ecological environment of the island. Although PI is in rapid urban development and construction, the island maintains secure and stable ecological conditions. PI is used as a research case to analyze the sustainable development of the ecological environment through the carrying capacity of the island ecosystem.
Highlights
The status of ecological carrying capacity is a major research topic at home and abroad, but the ecological carrying capacity of islands under rapid urbanization has been rarely explored
The methods of ecological carrying capacity analysis are divided into the following categories: logistic equation method, resource supply and demand balance method (Liu & Borthwick, 2011), ecological footprint method, energy analysis, Miami model, resource difference method (Peng, Wang, Li, & He, 2014) state space method, index system method of sustainable development, system model, multi-objective programming model (Sun, Chen, & Tian, 2018), and spatial decision support system
The results show that water area significantly impacts the per capita ecological footprint of Pingtan Island (PI) and that the trend of the two is the same
Summary
The status of ecological carrying capacity is a major research topic at home and abroad, but the ecological carrying capacity of islands under rapid urbanization has been rarely explored. The author highlighted South Miaodao Islands’ basic carrying capacity and carrying capacity index and established the relevant evaluation model to comprehensive explore the sustainable development of the islands. Ma et al (2017) proposed a general conceptual model to systematically evaluate Dongtou Islands’ marine ecosystem carrying capacity and developed an indicator system. The general conceptual model of system evaluation of marine ecosystem carrying capacity is proposed, which includes the identification of carrier, the determination of carrier object, and the construction of evaluation index frame. The author evaluated the sustainable development of the coastal areas in Shanghai and Chongming Island (Changjiang Estuary). This system method is feasible and valid. This system method is feasible and valid. Wei, Guo, Wu, and Ye (2014) developed the conceptual model of “driving force-pressure-state -response-control.” An index system
