Fig. 7: Results of subsystem obstacle factor analysis.

The bar chart compares the obstacle degree values across the three systems (Environment, Value, Memory) for the four categories of industrial historical spaces. The x-axis represents the subsystems (E1 is Natural environment, E2 is Built environment, V1 is Historical value, V2 is Technological value, V3 is Artistic value, V4 is Social value, M1 is Material memory, M2 is Immaterial memory). The y-axis indicates the obstacle degree, with higher bars representing greater constraints on coordinated development.
