Abstract:
Urban ecological land has a cooling effect on the external environment, it can effectively alleviate the urban heat island problem. Determining the threshold of its temperature effect and defining the shape features that produce effective temperature effects have some research value. This paper based on RS and GIS technologies and combine with landscape ecology, determines threshold values as guidance, quantitatively analyzes the scope and critical intensity of urban ecological land temperature effects, and defines the critical area and shape characteristics that produce effective cold effects. The results show that the urban ecological land has a significant cooling effect on a certain spatial range around it; the patch area and shape index of the urban ecological land both had a significant negative correlation with the patch temperature; for the patch area level, urban water, urban grassland, and urban water the correlation coefficients are -0.5255, -0.5470, and -0.4781; for the patch shape index, the correlation coefficients are -0.5326, -0.3931, and -0.4942.
