摘  要:
Based on the structure of cultivated land use and quality and productive forces of arable land,the present situation of arable land use in Hunan province was analyzed,and pointed out the main problems in cultivated land use,such as:the large proportion of cultivated land with slop and less production,continuous deduction of arable land quantity,incisive conflict between human and land,decrease of arable land quality etc.It also predicted the demand on cultivated land because of food,economic crops,and non-agriculture construction in 2015 and 2020 respectively according to the future population,living standard per capita,the demand on total quantity of food in Hunan province with mathematics models,based on food-safety,economic development and ecological protection.
