“Internet +” eco-production and eco-tourism carried out by agricultural enterprises is one of ways to increase income.Urban economic development index evaluation value(u_1),agricultural enterprises’ eco-production and eco-tourism index evaluation value(u_2) and Internet popularity index evaluation value(u_3) constitute the ternary coupling system.The ternary coupling coordination degree(D_3) combined with u_2 can be used to judge whether the agricultural enterprises practise eco-production and eco-tourism mode.When u_2≥ 0.5000,D3≥0.6000,the autonomous mode for agricultural enterprises can be used; when 0.4000≤u_2< 0.5000,0.5000≤D_3< 0.6000,the mode of cooperation with travel agency can be used; when 0.3000 ≤u_2< 0.4000,0.4000 ≤D < 0.5000,the tourism business transfer mode can be used; when u_2< 0.3000,D < 0.4000,the tourism business should not be carried out.All the above four modes require “Internet +”.
