Abstract
Since 1968, Area Division System has controlled urbanization and protected the agriculture environment and the other nature. However, new urban form is required in a situation of a population decline and shrinking financial resources in a local city. Concentration urban functions and an urbanization for low carbon society gained recognition in plans including the location adequacy plan. Plan making of these should be initiated with an appropriate evaluation of present aspects of city.
From these backgrounds, in this paper, we aimed to clarify a relationship between the applying effects of the Area Division System and an urban compactness from the viewpoint of environmental burdens, and to obtain the knowledge for the realization of concentration urban structure and low carbon society.
In this paper, at first, we organized a situation of applying the Area Division System and urbanization characteristics in case study from land use and urban facilities convenience. Then we calculated carbon dioxide emissions by city activity. Moreover, we analyzed a factor to affect the carbon dioxide emissions at investigation zones in each city. At last, we arrange the influence that Area Division System and the CO2 emissions distribution situation and municipal facilities location give to a CO2 discharge from the viewpoint of applying Area Division System.
Conclusions we obtained are as follows.
1. From the result of quantification theory I, main factor of CO2 emission is “Land Use Regulation” at both city. Moreover, from the viewpoint of convenience of public facility, the distance from “General hospital” and “Large scale retail store” have a large effect on the CO2 emission. In Area Divided City, the emission become higher near the city center. On the other, in Non-Area Divided City, it becomes higher at the area of far from city center.
2. From the distribution of predictive value, in Non-Area Divided City, high predictive value tends to concentrate along the trunk road and near the use district at the suburbs. In Area Divided City, it was concentrated to the central district. It is thought that applying the Area Division System has some positive effects to prevent CO2 emission.
