Quantifying and Comparing the Cooling Effects of Three Different Morphologies of Urban Parks in Chengdu

Urban parks have significant cooling effects, which can both mitigate the urban heat is-land effect and are crucial to sustainable development of human habitat. Although studies been conducted explore influence park morphology on parks, they not sufficiently in depth. Therefore, this paper took 117 central city Chengdu as research objects based perspective quantitative classification morphology. Then, remote sensing interpretation, spatial statistics, regression analysis were used, four indicators intensity, distance, area, efficiency integrated different morphological types parks. The results show that (1) could be divided into five categories, among round was best, 0.7. (2) In terms parks’ area perimeter thresholds 30 ha 4000 m, respectively. (3) When reached 70 3000 respectively, increase distance slowed down. (4) best when shape index (indicating complexity boundaries) 2.8. study provide theoretical support for intensive use green space help construction promotion a beautiful livable Chengdu.
