Abstract: Danzhou is the largest city in Hainan Province，and the adjustment of agricultural industrial structure in the city is the epitome of those occurred throughout the whole province. Development strategies were put forward based on analyzing the adjustment of agricultural industrial structure in Danzhou. According to the statistics from 2000 to 2014，the ratio of agricultural industrial structure change and its coefficient of variation were computed，and the change characteristics of industrial structure，especially agro-industrial structure were analyzed in the past 15 years. The results showed that：（1）Agricultural foundation status was further strengthened. Industrial development was lagging behind，and tertiary industry grew very rapidly. The proportion of the primary，secondary and tertiary industries was 54.2 percent，18.0 percent and 27.8 percent respectively in 2000，and adjusted to 49.0，14.9 and 36.1 in 2014. （2）The percentage of crop-plantation in agricultural production value declined annually from 2000 to 2014，and the internal structure of crop-plantation changed dramatically. The area ratios of grain crops，economy crops，vegetables and fruits were 32.7，52.8，and 14.5 respectively in 2000 and adjusted to 28.0，54.3 and 17.7 in 2014.（3）The sown areas of grain crops，oil-bearing crops and actual existent area of fruits decreased，but rubbers forest and vegetables increased during 2000 to 2014. The areas of sugarcane and artificial forestation had very big fluctuation during the same period. At last，countermeasures of agroindustrial structure adjustment and optimization were put forward in Danzhou，to provide important reference for the development of Hainan agriculture.
