| Abstract: |
| Low temperature and continuous-rain is an important factor that affects the flowering fruit bearing
stage of wax apple in Hainan Island，it leads to blossom drop，fruit drop and fruit cracking. In order to adjust wax
apple planting structure，alleviate the impact of low temperature and continuous-rain disasters，this paper used the
historical meteorological data in 1994-2014 from 18 meteorological stations in Hainan Island and disaster situation to
build the climate model based on biological characteristics of wax apple. Combined with wax apple cultivation area，
per capita GDP，boundary data and other data，this paper built disaster-causing factors hazard，vulnerability，
disaster prevention capability，and evaluated the comprehensive climate risks. The results indicated that risk zoning
of low temperature and continuous-rain showed significant latitude zonal distribution pattern，risk value decreased
from north to south. High risk zones were located in the north of Hainan Island，moderate risk zones were located in
the zonal region of northwest，middle part and northeast，low risk zones were located in the southern and western
regions in Hainan Island. |
