Estimation of return period of rubber wind disaster in Hainan Island

Studying the return period of maximum wind speed is a objective evaluation method of rubber wind damage. Based on the maximum wind speed from 1981 to 2010，the maximum wind speed for 5，10，20，30，50 years return period was calculated in Hainan Island by extreme value type I distribution function. Different return periods of rubber wind damage loss distribution were estimated through wind and rubber wind damage corresponding table. The results showed that in 5，10，20，30，50 years return period of maximum wind speed，the rubber disaster losses ranged from 5% to 16%，10% to 24%，16% to 33%，16% to 33%，24% to 45%，respectively，and the distribution of rubber disaster losses had obvious differences in space.
