Integrative Fuzzy Set Pair Model for Land Ecological Security Assessment: A Case Study of Xiaolangdi Reservoir Regions, China

摘要

An integrative fuzzy set pair model, established by integrating fuzzy assessment and set pair analysis, was introduced to assess the land ecological security states. The approximate degree of land ecological security to the optimal standard set was calculated to describe the security level by combining multiple indices. The indices and weights were determined by Delphi and fuzzy AHP (Analytic Hierarchy Process) respectively. The model was validated and applied to the case study of Xiaolangdi Reservoir regions.
