| Outline of Final Research Achievements |
We proposed new methods which estimate population distribution taking into account of building distribution in steep slope area. Method 1 estimated population distribution based on using number of residents and Method 2 estimated population distribution based on 3 types of resident categories. Comparing estimated population using each method, there were statistically significant differences between the results from conventional method and those from proposed methods. The proposed methods can estimate population exactly reflecting the density of buildings on the steep slopes.
We verified the estimated population in the steep slope collapse hazard area using building data. The result of the proposed population estimation methods reflects the actual population distribution much better than that of the conventional method. The estimated population around the steep slope areas from the proposed methods was useful information to evaluate each steep slope.
