Abstract: Based on the feature of ecological restoration of abandoned land in a large surface coal mine, this paper systematically analysed constructing process of the intelligent decision support system of ecological restoration of abandoned land in the large surface coal mine(ALERIDSS)by applying the principle of software engineering. The system analysis, requirement analysis, and software desigh were discussed in detail. The overall structure of the ALERIDSSincluding integration of database management system, expert system, graphic management system, model management system and user interface system was constructed. The exploiting work was attempted to intellectualize the decision process of ecological restoration with graph and some necessary specification. Experimental results showed that the goal of intelligent decision has been reached.
