Based on the statistical data of 18 cities or counties in Hainan from 2011 to 2018, this research comprehensive utilize agricultural production comparative advantage and environmental comparative advantage to build a comprehensive comparative advantage system, guide the optimization of Hainan's agricultural industry layout. The result show that the comprehensive comparative advantages and environmental bearing capacity of Sanya, Qionghai, Wanning, Baoting and Qiong Zhong are bigger than 1, have significant advantage in agricultural production; And the comprehensive comparative advantage of Ding'an, Tunchang and Ledong is bigger than 1, but the environmental carrying capacity is between 0-1, so they are medium advantage zone of agricultural production; The comprehensive comparative advantages and environmental carrying capacity of Haikou, Wenchang, lin'gao, Danzhou, Dongfang, Lingshui and Changjiang are all between 0-1, are disadvantaged area of agricultural production. According to the evaluation results of comprehensive comparative advantagesw, the following optimization paths are proposed, firstly, it is proposed to improve the significant advantages zone, and limit the scale of low efficiency and high consumption of agricultural products in medium advantages zone, and adjust the industrial structure and layout of the disadvantaged zone. Secondly it is proposed to promote the production mode of comprehensive development of agriculture, forestry, animal husbandry and fishery. Thirdly, it is considered of multi compliance of the impact of planting, animal husbandry and fishery layout on the environment. Then the pollutant discharge in agri-production should be strengthening controlled. Finally, this research puts forward some policy suggestions to support the optimization of regional layout of agricultural industry.
