Abstract: To solve the problems of high cost in time and labor in traditional experimental methodologies, on the spot investigation and the similarity of soil and climate situations between different coal mine dumping areas, the fuzzy integrated evaluation, gray relating superiority analysis algorithm, distance-based similarity models and rule-based reasoning were used to make the decision on the potential evaluation, proper plant species and land reclamation schemes selection. A web-based decision support system for land reclamation in abandoned coal mine land was developed with ASP.NET and MS Access. The developed system can be treated as a new method for land reclamation for abandoned coal mine land. Finally, Fuxin colliery, Liaoning Province in northeast China was selected as the case study and site use area, the prototype system was proved to be scientific, reasonable and feasible form the pilot using.
