The Scale Variation and Spatial Heterogeneity of Regional Temperature Influenced by Green Infrastructure(GI)Pattern-An Empirical Evidence Based on Tianjin
Green Infrastructure(GI)plays an important role in regulating regional temperature.The existing researches mainly focus on the influence of quantity on climate factors,but there is insufficient discussion on the scale variation of GI pattern and its spatial heterogeneity.Taking Tianjin as an example,the scale effects and spatial patterns of GI patterns affecting regional temperature are explored by integrating landscape ecology and geographically weighted regression model.The results show that:1)The Gl pattern can significantly affect the regional temperature,and the correlation coefficients of each pattern index and regional temperature show a trend of increasing and then decreasing,and reach the peak at the scale of 7km x 7km;2)The correlation degree of each GI pattern index and regional temperature has obvious differences,with the overall area index＞aggregation index＞density index＞shape index;3)The correlation between each pattern index and regional temperature has a spatial non-stationary feature,among which the regional temperature in semi-urbanized areas is more susceptible to the influence of pattern changes.Finally,the optimization measures of GI pattern are proposed to provide scientific guidance for the design of climate adaptation planning and the formulation of various related policies.
