Abstract: Urban environmental planning is the major channel to control the
human activities from polluting the environment. Urban environmental quality
evaluation is prerequisite of proper urban planning. Fuzzy Set Theory has been
used as an aid to urban planning. In this research work, environmental as well
as physical environmental components have been considered to evaluate the urban
environmental quality. Because of the fuzzy uncertainty and spatial
characteristic of environmental phenomenon, the integration of fuzzy set theory
and geographic information system is used in urban environmental quality
evaluation of study area, Bhopal (Bhopal municipal corporation limits).
Analytical hierarchy process has been used to find out the weights of criteria
by pair-wise comparison matrix. Fuzzy overlay is carried out by using fuzzy
inference network (fuzzy operators) to coalesce criterion maps. Validation of
the final quality map has been done through sample data. Accuracy assessment
(error matrix) has been calculated. It reaches to the conclusion that FST
approach reflects the urban environmental quality evaluation in more detail and
in more precise manner than the conventional (Boolean) approach.
