A Quantitative Analysis on the Mitigation of City Temperature by the Open Spaces in Urban Area

Abstract

In this paper we extend our investigations of climatically analysis of open spaces in Suginami, Tokyo which we have mentioned in our previous paper.
We have discussed several research techniques and selected the most precision methods.
We have caluculated air temperature by the value of open space ratio using the regression equations.
The fixed regression equations are as follows.
1. Y: Maximum temperature in summer.
Y=-0.024 X₁-0.179 X₄+C (S.E of Y=±0.892)
2. Y: Mimimum temperature in summer.
Y=-0.026 X₁-0.025 X₂+C (S.E of Y=±0.488)
(X₁: forest (%), X₂: grassland (%), X₄: water surface (%) in district area.
C: constant.)
