By constructing the calculation model of the optimization degree of forestry industrial structure,this paper quantitatively evaluates the optimization degree of forestry industrial structure in Hunan Province in 2017 from three levels:provincial level,city(prefecture)level and county(city,district)level.The result indicates that the degree of optimization of forestry industrial structure in Hunan Province has increased from 2015 to 2017,but it is still below the passing line,and the optimization degree is not high.Among all the cities(prefectures)in the province,the optimization degree of fore...
