Land reclamation information system of mining area based on GIS

摘要

Land reclamation of mining area is an interdisciplinary. The data to be dealt with involves the fields of mining, geology, geography, soil, agriculture and forest, biology, society, economy, etc, with the characteristic of plenty of data and complicated relationship. The traditional data processing cannot meet the demand of land reclamation. The research is based on the result of prevenient scholars to further study the application of GIS. In the paper, the connotation and functions of Land reclamation system is mainly explained, and data organizing pattern is systematically analyzed based on MapX and Oracle Spatial, then a new method based on GIS and CA is putting forward to simulate the distribution of digging area and filling area on the condition of the earthwork balance, finally a reclamation land use mode of rational proportion and layout is set up based on analyzing methods of GIS and the optimizing method of GA. The research can provide a useful tool for land reclamation management and decision-making.
