Reclamation suitability evaluation is the basis for determining the reuse direction of damaged land. Most scholars’ studies have focused on the improvement and innovation of evaluation models and methods, while the analysis of restrictive factors is rarely involved. This paper evaluates the reclamation suitability of damaged land around Longchi coal mine by the integrated index method and the analysis of restrictive factors is carried out by the difference-product method. The result shows damaged land around the Longchi coal mine is most suitable for being reclaimed as woodland. The main restrictive factors are the degree of contamination of the soil and water and the irrigation conditions. This study provides a basis for the rational reutilization and improvement options of damaged land around Long Chi coal mine. The study also verifies that the combination of the integrated index method and the difference-product method work well for evaluating reclamation suitability and for analyzing restrictive factors in case of no prominent evaluation indexes.
