Abstract
For basis of urban environmental planning, we studied air pollutant (NO_x) emission structure. In Parti, we analyzed characteristics of emission source activity type which can explain emission structure comprehensively. Based on the result of Part 1, we studied characteristics of regional emission variance in this Part 2. For obtaining general property of regional emission structure, NO_x emission sate of Tokyo Metroporitan area is studied by mesh data analysis of emission source activity type. The present study provided following conclusions ; Characteristics of regional emission variance can be explained by emission source activity types and these compound location reflecting land use pattern (see Table 1, Fig. 3). 4 types of regional emission characteristics are derived through cluster analysis of emission component by mesh data, (see Table 3, 4). Methodology and fundamental informations to grasp regional emission structure which is consist of a process from land use to emission pattern, are obtained.
