This paper firstly introduced the development prospects of natural rubber in Thailand, discussed the general situation of rubber tree planting in Thailand, and analyzed the natural rubber harvested area, per unit area yield, yield and natural rubber exports in Thailand. The results showed that the annual average natural rubber harvested area in Thailand increased by 1.21% from 1980 to 1990; the annual natural rubber harvested area increased by 4.27% from 1991 to 2011; the annual average natural rubber harvested area in 2012-2016 increased by 5.65% per year; from 1980 to 2004, the per unit area yield of natural rubber in Thailand showed a rising trend, and rubber yield from 2005 to 2016 showed a decline trend; from 1980 to 2016, Thailand's natural rubber yield showed a wave-like rise. In recent years, natural rubber production has changed little. In 2015, the yield fell by 2.19% compared with 2014, and in 2016 it increased by 0.22% compared with 2015; from 1981 to 2016, the export volume of natural rubber in Thailand basically showed a trend of rising with large fluctuation. In recent years, the export volume of natural rubber in Thailand accounted for 74%-82% of natural rubber yield in that year. Finally, it is found that the harvested area of natural rubber in Thailand will continue to decline in the next few years, it is difficult to increase the yield, the proportion of natural rubber exports and yield will gradually decline.
