Abstract:
In order to research the effect of landscape pattern and ecological effects caused by land reclamation project in mining area,taking land reclamation project of Jiuli mining area in Xuzhou, China as an example, the land use structure and landscape pattern changes were analyzed based on GIS and method of landscape ecology. The ecological effects of mining area were evaluated with an indices system which was constructed with optimized landscape pattern and the weight was assigned for each index by AHP method. The results showed that the ecological environment of Jiuli mining area was improved as a result of the land reclamation project, while several indexes had both positive and negative effects on the ecosystem. The positive effects were indicated by the increased average patch area,ecosystem services value,density and area of corridor,biodiversity, etc. The negative effects to ecosystem in coal mining area were indicated by decreased fraction dimension and changes of original landscape. Conclusion demonstrated that ecological compensation should be carried out by measures as biological, engineering, technology during the land reclamation.
