Risk Assessment of Human-animal Conflict in Sanjiangyuan National Park
The human-animal conflict risk map reveals the spatial pattern of risk and helps to identify priority areas for mitigating the risk of wildlife accidents.This study takes four counties involved in Sanjiangyuan National Park as research area and the township as the research unit.Based on the regional disaster system theory,we constructed a human-animal conflict risk assess-ment model from four aspects:the risk of disaster-causing factors,the sensitivity of hazard-bearing environment,the vul-nerability of hazard-bearing bodies,and risk prevention capacity,and comprehensively evaluated the spatial risk and over-all risk of human-animal conflict in the study area.The results showed that the factors affecting the risk of human-animal conflict included animal density,number of incidents,normalized difference vegetation index(NDVI),population density,wild prey density,distance from rivers,distance from settlements,and livestock density.The risk of human-animal conflict in Sanjiangyuan National Park has an obvious spatial differentiation pattern.The risk was generally higher in the central area than in the eastern and southern areas,and the higher risk areas were mainly distributed in the townships of Zhidoi County and Qumarleb County in the Yangtze River Source Park,accounting for 97.07%of the area.It is concluded that the risk of human-animal conflict in the Sanjiangyuan National Park is generally high.The results of the study provide a scien-tific basis for determining the factors influencing the risk of human-animal conflict and precise prevention and control of wild-life accidents.
