摘要: Intrinsic uncertainties within geo-hazards affecting the source area of Lishui River region exhibit chief challenges for environmental management and regional development. This study employs a fuzzy multiattribute approach to rank eco-environmental vulnerability 38 given geographic units in area. The closeness coefficients alternatives are applied sort based on distances from positive-ideal negative-ideal solutions. multiple attributes used ranking geological characteristics, hazards, human impacts. In general, results method consistent with those synthetic index method. Our suggest that configurations/characteristics associated range density critical determinants vulnerability. Human activities, however, slightly increase overall units. Results aid preliminary resource exploitation protection, yielding support long-term sustainable development region.
