In this paper, the theory of system optimization as a guide to the pilot area in Li County, for example, using the combination of dominant factor grading, gully area on the loess plateau site classification, and the use of expert advice fuzzy comprehensive evaluation of land suitability assessment by Construct the comprehensive benefit index and quantify the target of regional land use planning. On this basis, the multi-species, multi-species and multi-objective land-use planning decision-making model is established, and the planning plan is put into practice. For the comprehensive management of the Loess Plateau and agricultural development to explore a through the rational development and utilization of land resources, adjust the land use structure, to achieve sustainable development of regional agricultural economy, a new way
