An Ideal-Point-Based Approach to Coal Mining Area Land Development Suitability Evaluation

摘要

The concept of coal mining area land (CMAL) development suitability was defined, and evaluation index system of CMAL was constructed by AHP. Considering the characteristic of linguistic-based attribute, an ideal-point-based approach to CMAL development suitability evaluation was introduced. Based on the definition of positive ideal-point and deviation, deviation between alternative and positive ideal-point of alternative were given, and the process of ideal-point-based approach to CMAL development suitability evaluation was also provided. Taking Jixi coal mining area in Heilongjiang province as an application case, and its land development suitability was evaluated. The result shows that the method of ideal-point-based approach to CMAL development suitability evaluation is effective.
