Abstract:: Taking Zhoukou City of He’nan Province as an example, and selecting statistical data from 2000 to 2008, this paper studied the sustainability of agricultural land in Zhoukou City from the perspective of energy. The results showed that: agricultural inputs were mainly dominated by the purchasing resources, the proportion of which exceeded 90% of the total energy input, and industrial inputs largely depended on the inputs of fertilizer and pesticide, precipitation significantly affected the investment of renewable environmental resources; agricultural outputs were mainly dominated by the crop growth and livestock, the proportion of which about 99%, the fishery and forestry took a very low percentage, the structure of agricultural outputs was relatively simple; the economic sustainability of agricultural land use has achieved initial success, while ecological sustainability and social sustainability were at lower levels, the index of sustainable use indicated that agricultural system had great vitality and a greater potential for development; the unsustainability was expressed by a large number inputs of fertilizers, pesticides and a single structure of agricultural outputs.
