In December 2015,the Central Rural Work Conference put forward the structural reform of agricultural supply side,to ensure the national food security. At present,china's grain production is increasing,the supply and demand structure of grain market is not balanced,and the ineffective supply due to the lack of market supply and demand has caused the problem of structural surplus and structural *** price and quality difference of domestic and international grain is obvious,and the agricultural products in china are overstock,so the reform of agricultural supply side based on food security must be implemented. To adjust structure,reduce stock,reduce cost,increase quality,promote the primary,secondary and tertiary industries convergence will become the focus of china's agricultural supply side structural reform,and we can develop the ecological agriculture,improve the competitiveness of the grain market in price and quality,to ensure food security for the nation.

With the promotion of agricultural ecological civilization construction in china, agricultural ecological security has received increasing attention. How to ensure agricultural ecological security has become a great concern for many scholars. As an important agricultural province in china, Hubei is of great significance to Chinese food security and agricultural sustainable development. This paper aims to establish an index system of agricultural ecological security and security classification of Hubei via Analytic Hierarchy Process and Pressure-State-Response methods. An evaluation of agricultural ecological security in Hubei, with a base of the national average value in 2015, reveals that the security degree has increased by 0.07566 from 0.90150 in 2005 to 0.97716 in 2015. Results show that agricultural ecological security in Hubei has improved but failed to reach the national average and there is still large space for improvement of the security level, considering a trend of deterioration in some indexes, such as per capita water resources, population density, per unit area pesticide load of farmland, forest coverage, grassland degradation rate and average annual precipitation. Influencing factors, especially population spatial distribution, misconduct in agricultural production, insufficient ability in agricultural natural disaster prevention, deficiency of agro-ecological technology of agricultural ecological security in Hubei are analyzed. For improvement of the degree of agricultural ecological security in Hubei, some countermeasures and suggestions are discussed.
