Mining land reclamation in Neiqiu County based on matter element model

In order to obtain mining land reclamation scheme reasonably, the matter element model was proposed. Through analyzing the characteristic of matter element including divergence, extension, interrelation and conjugation, the land reclamation matter element model was constructed. The eigenvalues of land reclamation matter element model are nature state, geology structure, reclamation process, mining subsidence state, present mining condition, financing, policy and protection consciousness. The author applied the matter element model to establish scheme collection. Then qualified schemes are selected preliminarily according to the measured value. The following step is establishing another appraisal matter element model, which eigenvalues are land production, cost, farmer per enhancive income, ecosystem stability, biodiversity, landscape diversity. In the appraisal matter element, Shannon index reflects biodiversity and affinity analysis reflects landscape diversity. Through the appraisal matter element model dependent function between preliminarily schemes is set up. Finally, the most excellent one is selected by the optimal appraisal method. Moreover, a design process of land reclamation in Feng Village mining subsidence was introduced. The result shows that the matter element model is extension and logical.
