Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
As widespread features of landscape and human disturbance paths, road networks bring forth many ecological effects and affect the regional land ecological security. In this paper, the methods of GIS buffer were used to elucidate the influence of roads on landscape and assess the road impacts on land ecological security in Hengshan county. Land use change greatly with different buffers. Landscape fragmentation (Ci), landscape division (Ai), landscape dominance (D) in 500 m buffer zone differed greatly between different land uses. Then based on different ecological effects on pattern and process, we put forward ecological security index of pattern and process, then comprehensively assessed various potential and accumulative ecological effects of road networks. The results indicated that though ecological security distributed differently in each town area, the road density had high negative linear relationship with the security levels.
