In this paper we tried to analyze agricultural land use changes in Beijing City, and make clear their spatio-temporal structure. The sectoral structure of cultivated land is closely related to the physical land conditions, so that distribution of agricultural land use is basically determined by land conditions, which is one of the basic driving forces. As regards food crops cultivation, its sectoral structure is closely related to the driving forces as complex of land conditions, industrialization, policies, infrastructure and innovation. Although the sectoral structure of vegetables cultivation is closely related to the available land conditions, it is more important for them to develop alternative economic activities with the growth of urbanization and socialist market economy. On the other hand, the sectoral structure of fruits production is most closely related to the enlargement of profitability with the growth of urbanization and socialist market economy rather than the available land condition and alterative economic activities. Following our discussion, it seems to be concluded that sectoral differences of agricultural land use in Beijing City have been generally presented since the 1980s. This sectoral structure has been closely related to the complex of driving forces such as land conditions, agricultural policies, the alternative economic activities and urbanization. In addition, we calculated through mesh data of village and township statistics in Beijing City. Food crops productivity will be raised greatly due to constant agricultural technology innovation, and food crops land ratio will rise to 75% by 2020. Vegetables productivity will make marked progress in the inner urban fringe, and it will decrease greatly in the outer urban fringe of Beijing City. Vegetables land ratio will also reach 15% by 2020. Types of fruits productivity and culture of fruits over Beijing City by 2020 will not change much than now.

Key words: agricultural land use, spatio-temporal structure, density of population, driving forces, Beijing City
