Abstract: Land use/cover change (LUCC) is one of the hot issues of global changes. The impact of land usechange on land productivity is an important part of effects of LUCC. Based on the concepts of land use changeand land productivity, this paper summarizes the main research contents and methods mainly from the aspect oftheir impacts on the potential land productivity, food production capacity and soil quality. It also discusses thescales of impact in this study. Then, it further points out main problems in current studies. Finally, the paper suggeststhat future research should focus on the impact of land use changes in the structure, pattern and intensityon cultivated land productivity, especially in the range of small scale, and emphasize the application of spatial analysis, dynamic evaluation model and synthesis of scales. This article also puts forward that this research hasbecome an inevitable strategic choice and it is of great significance to establish sustainable land use patterns andto ensure national food security.

Key words: food production, land productivity, land use change, soil quality
