Mined landscape ecological rehabilitation and a case study

Mined land reclamation involves landform reshaping, restoration of basic infrastructures, such as road, irrigation and drainage systems, reuse of derelict lands. To reach the purpose of ecological rehabilitation, it is necessary to reconstruct the elements of landscape, such as corridors, to allocate different types of land use in suitable position. Two indicators, the intensity of interaction between different patches and land use diversity are used for instructing the development of reclamation planning and design under the assumption that the structure of ecosystem is dependent on the structure of land use. The methodology of changeover matrix is employed to predict the trends of farmland area, which give us the answer to control the change of land use structure is to adjust such parameters as the farmland reclamation ratio. By a case study, we find that ArcGIS provides us a visual display and dataset management tool to develop a rational planning.
