These indices , to be shown by figure 1, fundamentally consist of 3 groups: Pollution Prevention , Nature Conservation, and Amenity. The individual indicator is presented by the model of relation between inhabitant's satisfaction(subjective value) and physical values (figure 2).

First, subjective value is obtained by surveying public opinion. Second, we collect and process physical data by small districts or mesh data. Third, we make “value functions” between subjective value and physical values(table 2). We integrated individual indices to middle indices, and also a total index by multiplying weights of each item.
