The Situation of Green Spaces development in Open Spaces produced by Urban Redevelopment

Abstract

The role of green spaces is very big under the situation that the necessity and importance of developing fine urban landscape is well recognized among citizens. Aud the creation of green spaces in the central urban area is strongly requested. This research aims to analyze how much green spaces were developed in recent 10 years in the system of so called “Specified block”, “Intensive land utilization district” and “Comprehensive design” which seem to be effective system to create green spaces in the central urban areas where it is quite difficult to acquire the land for developing public parks.
The research was carried out in the form of the questionnaire to the owners of the redevelopment project sites from Building Research Institute and 50.6% of them answered the questionnaire.
As the result, according to the histogram of the ratio of planted area to the open space area, mode is the 40% to 50% range in the case of “Specified block”, the 20% to 30% range in the case of “Comprehensive design” and the 0% to 10% range in the case of “Intensive land utilization district”. Then, the strong correlation was observed between “area of the project” and “area of open space”(correlation coefficient is more than 0.95 in every system) and rather strong correlation was observed between “the ratio of planted area to the project area” and “the ratio of planted area to the open spece area”(correlation coefficient is 0.89 in the case of “Specified block”, 0.73 in the case of “Comprehensive design” and 0.93 in the case of “Intensive land utilization district”).
