Abstract: The current status of land use in Dongying city, a major part of the Yellow River Delta, is dominated in terms of land types by farmland, water surface and unused land and its land use changes in the last 50 years are mainly reflected in a undulating trend of farmland area, the adjustment of agricultural structure and increase in non farmland area prevailed in the process of land use type transformation, and close relationship between farmland change with population and economic development. The sustainable land use of the region should follow the optimized principle and objective of adopting measures suitable for local conditions, bringing into full play superiorities, emphasizing synthetic benefits and protecting eco environment. Constrained analyses of sustainable land use are conducted concerning land use types including land suitability grades, cultivated area, land for forestry, land for animal husbandry, land devoting to settlements, industry and mining, land for transportation, water surface and unused land. Based upon which optimization structure and allocation schemes related to sustainable land use are raised such as returning grain plots to forest and grassland, increasing forest coverage, properly concentrating rural settlement locations, strengthening land consolidation, rationally reclaiming marshland, wasteland, grassland, saline alkali land.
