The damage rules of land resources in subsidence area is analyzed based on the theory of landscape ecology,taking the subsidence area of coal mining area in Jiawang District as the research object,the patch shape and area of subsidence land on the map of landscape were studied.The studied results showed that comparing with the standard plots,the patch indexes of subsidence land,such as average patch shape and area,are close to the high-qualified cropland,but scope of their change is larger.The patch numbers of land with area less than 500mu are more,account for the 65% of total plots and their area account for 27% of the total area.The changes of landscape structure for the reclamation project of Shanghu,Jiawang,is analyzed,the analyzed results show that the sustainable usability of land resources in subsidence area is improved apparently after the reclamation project is implemented.
