Abstract: The evaluation of the carrying capacity of agricultural resources and environment is the basic work for the preparation of land spatial planning. Research on the carrying capacity of agricultural resources and environment can not only maintain agricultural ecological security, determine the pattern of agricultural production, but also explore the balance between economic and social development and resource environmental protection, thereby improve land administrative ability. This paper takes Anren county, Chenzhou city, Hunan province, the main production area of national agricultural products as the research object, 
evaluates the carrying capacity of agricultural resources and environment of the county, conducts research on agricultural development potential, risk identification, and agricultural space demarcation. According to research, Anren county possesses abundant agricultural resources, has land area up to 63 705.49 hm² with agricultural resources environmental carrying capacity at or above tier III, 43.57% of the total land area. It also has a land area of 18 678.51 hm² with agricultural developing potential, 12.77% of the total land area. Anren county belongs to hilly terrain of southern China, with abundant water and land resources, good environments and high agricultural developing potential, but its agricultural development is largely limited by ecology with certain ecological risks and conflicts during farmland protection and agricultural structural adjustment. According to the investigation and analysis, the conflicted land area is 7 105.15 hm², 4.86% of the total land area. The agricultural space is identified according to the spatial pattern characteristics of resources and environment carrying capacity. The agricultural space land area of Anren county is 49 616.65 hm², accounting for 33.93% of the total area of the county, and it is clear that the county belongs to the spatial pattern of agricultural development of "two basins and one corridor".This provides a scientific basis for locking the target area of comprehensive agricultural management and improving the capacity of land spatial management. The grade of the carrying capacity of agricultural resources and environment is affected by the importance of ecological protection, land resources, water resources, natural disasters and other factors. In Anren county, there are many overlapping areas of current cultivated land, permanent basic farmland, reserve resources of cultivated land and extremely important and sensitive areas of ecological protection, and there are a lot of agricultural lands such as planting gardens and breeding ponds in areas with low carrying capacity.Paying attention to the problems in the protection of cultivated land in mountainous and hilly areas, adapting measures to local conditions and making good use of land with various levels of agricultural resources environmental carrying capacity is of great significance to effectively resolving the ecological risks in the adjustment of agricultural industrial structure.
