摘要: 土地利用变化对土地生产力的影响是土地利用/覆被变化(LUCC)效应研究的重要内容之一。本文基于对土地利用变化和土地生产力概念的辨析, 着重从土地利用变化对土地生产潜力、粮食生产能力和土壤质量3 个方面的影响, 总结梳理了当前的主要研究内容和方法, 探讨了研究的影响尺度特征。最后指出今后的研究应加强土地利用结构、方式和强度变化对小尺度范围内耕地生产力的影响, 强化不同尺度的综合以及空间分析和动态评估方法的应用。

关键词: 粮食生产, 土地利用变化, 土地生产力, 土壤质量

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
