Research on the Complexity of Forms and Structures of Urban Green Spaces Based on Fractal Models

Figure 4

Three schemes for the center, radius, and scale analysis. (a) Taking the city administrative center as the center, the geometric scale of radius r = 60, 120, 240, …, 61,440 m, a total of 10 sets of data points. (b) With the center of gravity of the study area as the center of the circle, the geometric scale of radius r = 25, 50, 100, …, 51,200 m, a total of 11 sets of data points. (c) Taking the center of urban green space (removing the woodland type) as the center of the circle, the radius r = 1000, 2000, 3000, …, 27,000, a total of 27 sets of data points.
