Regional Land Eco-Security Evaluation for the Mining City of Daye in China Using the GIS-Based Grey TOPSIS Method

Abstract: Regional ecological security assessment is a significant methodology for environmental protection, land utilisation, and human development. This study aims to reveal the regional constraints of ecological resources to overcome the difficulties and complexities in quantification of current models used in land ecosystems. For this purpose, the technique for order preference by similarity to an ideal solution (TOPSIS) was linked to a grey relational analysis and integrated with a geographic information system.

“…TOPSIS is an MCDM method widely used by practitioners for analyzing and prioritizing alternatives based on certain criteria. TOPSIS first identifies the ideal solution and compares all alternatives with the ideal solution [17,18]. In TOPSIS, there are two ideal solutions: the Positive Ideal Solution (PIS) and Negative Ideal Solution (NIS).…”

“…Therefore, through scientific evaluation of the factors on which the ESI is based, policies can be formulated to improve the situation. This approach also makes the work of ecological protection more refined and targeted, which is of great importance considering China's current state of development and environmental protection [21,22].…”

“…The change from the conventional supply chain of fresh agricultural products to the new agricultural product supply chain is crucial for fresh agricultural products in China. The use of advanced technologies and a new supply chain operating mode increases the value of the fresh agricultural commodity supply chain while lowering conventional supply chain danger (Zhang et al, 2021). Simultaneously, it adds a new threat.…”
