海南岛橡胶(Hevea brasiliensis)寒害风险区划
Risk zonation of chilling injury of Hevea brasiliensis in Hainan Island
摘要
Abstract
Chilling injury is one of the main meteorological disasters to Hevea brasiliensis in Hainan Island. Risk zonation of chilling injury would effectively improve the prevention capability of H. brasiliensis from chilling injury. With the meteorological data from 1964 to 2016,H. brasiliensis cultivation area,yield,and social-economic data from 1988 to 2016,four factors of chilling injury ( chanciness of disaster-causing factors,sensitivity of disaster-inducing environment,vulnerability of disaster-affected bodies,and capability of disaster prevention and reduction) were selected to construct the risk assessment model of chilling injury on H. brasiliensis based on the risk formation mechanism. The risk index of chilling injury to H. brasiliensis was calculated and five grades of risk were classified following the natural breakpoint method. The results indicated that the risk of chilling injury was higher in northwestern and central parts than in other coastal areas. Lingao area had the highest risk,followed by Wuzhishan mountain area in central part. The coastal areas of Dongfang and Ledong of southwestern parts,and Haikou and Wenchang in north part had the lowest risk. There was no chilling injury risk in Sanya and Lingshui.关键词
