Abstract—In the context of land use change, the regional environment in the Northeast China is affected by various factors. Combining with the theory of risk assessment, the evaluation indicators of ecological risk assessment were chose from aspects of hazard, exposure and vulnerability in this paper. And then the comprehensive evaluation model was utilized to obtain the ecological risk index value at a gird scale of 30m×30m. The results showed that, although the ecological risk value is not so high in the whole Linjiang area because of the special geographical location, the forest quality and structure has been severely degraded, due to the imbalance of forest harvesting and tending in the recent decades. It can be seen from the distribution map that the ecological risk in Linjiang area has a very significant phenomenon of spatial difference.

Index Terms—Ecological risk assessment, ecological risk indicator system, land use change, Linjiang area.
