Abstract: On the basis of land classification and land evaluation, this paper analyses the land structure of the Yellow River delta. The main contents and conclusion are shown as follows: 1. Land type structure reflects the natural character and conditions of the land in the Yellow River delta, as well as the rule of regional differentiation at a middle scale. 2. The analyses of land resources structure comprises two aspects, land quality grade and land suitability. In the Yellow River delta, the general quality of land is lower but its developing potential is high. The suitable utilizaion is farming, animal husbandry and fishery. 3. The analyses of land space structure show that there exist an evident differentiation of land types changing successively in the Yellow River delta, which can form a kind of ideal land use pattern of farming animal husbandry fishery from fan shaped top to the border of the delta. 4. The land succession structure shows the successional rules of the land in the Yellow River delta region. We should master these rules to promote land consequent succession and avoid land degeneration. It is particularly important in the delta because its ecological environment is frail. 5. Current land use structure reflects that the development of the land in the Yellow River delta is at a primary level and there are many land use problems. The current land use structure needs to be regulated. In agricultural development, we should utilize the natural rules gotten from analysing land structure to set up modern and sustainable bases for farming, animal husbandry and fishery in the Yellow River delta region.

Key words: the Yellow River delta, land structure
