Abstract: Based on the results of the survey of the current situation of ecological environment in Anhui Province,cultivated land is the main type of land use.As a result of economic construction,ecological construction,economic benefit driven activities and limited back-up resource,the acreage of cultivated land is decreasing year by year.Insufficient nutrient supply,land degradation,soil erosion and some other factors affect the quality of the cultivated land.The lower ecological footprint shows that the increasing population has been causing an enormous ecological pressure to the environment.The conflict between the men and land is getting more and more prominent.Guarantee of food supply depends more and more on highly intensive utilization of the cultivated land,increased application rate of chemical fertilizers and expansion of the effectively irrigated area.However,the guarantee of sustainable utilization of the cultivated land is to intensify land management,strictly enforce the land related laws and regulations,proper plan for land use,increase the grain yield per unit area and the degree of land use intensity with the aid of science and technology.

Key words: cultivated land resource, sustainable use, equilibrium of overall cultivated land, Anhui Province
