Abstract:
Typhoon disaster is the most serious disaster for rubber planting in Hainan province.This study took Hainan island,a major natural rubber producing area in China,as the research object.Based on the disaster risk assessment theory,the risk,exposure and vulnerability assessment model of rubber typhoon disaster was established combining rubber typhoon disaster with social economy and meteorological data.The weighted comprehensive evaluation method was used to evaluate the risk of natural rubber forest disaster.Results show that the high-risk areas of rubber planting in Hainan province locate in the coastal cities and counties where frequent typhoons occur,among which,Qionghai,Wenchang,and Haikou are the areas with the highest risk of rubber disaster in Hainan island,and Lingshui,Wanning,Qiongzhong,Tunchang,and Dongfang are also the areas with higher risk of disaster.The areas with the lowest risk are in Wuzhishan,Baoting,Ledong,and Sanya.The evaluation results are consistent with the actual disaster and planting conditions.The evaluation results show that the dangerous of typhoon disaster is the main factor of risk,but it is not the single determinant,planting technology,cultivar improvement and other technical measures play an important role in reducing the vulnerability.The evaluation results can provide a basis for preventing disaster and planting layout of rubber forests.
