Research in the field of industrial heritage regeneration suffers from high subjectivity and low reliability in design and evaluation. The study takes seven regeneration projects of the Kailuan family of industrial heritage as examples, designs four optimisation and improvement strategies and constructs an evaluation system containing four intermediate layers and 23 indicator layers based on the evaluation factor method to realise the evaluation of design solutions. The average evaluation value of the four intermediate layers was approximately 0.65, and the average evaluation value of the 23 evaluation indicators was approximately 0.68. The evaluation values of the four intermediate layers for the seven Kailuan projects showed that the evaluation of the park and the evaluation of the participants’ perceptions were roughly higher than the standard values, while the evaluation of the buildings and the evaluation of the environmental image had lower evaluation values. The correlations between the park evaluation and the other three intermediate level evaluation indicators were all over 0.500, and all had positive correlations, while the correlations between any two of the remaining indicators were weak and not statistically significant. The regenerative landscape design and evaluation of the Kailuan system of factory heritage enriches the current landscape design evaluation system and provides corresponding optimisation strategies for landscape optimisation design.
