| Abstract: | A fuzzy decision analysis method for integrating ecological indicators was developed. This was a combination of a fuzzy ranking
method and the analytic hierarchy process (AHP). The method was capable of ranking ecosystems in terms of environmental conditions
and suggesting cumulative impacts across a large region. Using data on land cover, population, roads, streams, air pollution,
and topography of the Mid-Atlantic region, we were able to point out areas that were in relatively poor condition and/or vulnerable
to future deterioration. The method offered an easy and comprehensive way to combine the strengths of fuzzy set theory and
the AHP for ecological assessment. Furthermore, the suggested method can serve as a building block for the evaluation of environmental
policies. |
