耕地集约利用研究进展与展望

耕地集约利用关乎国家粮食安全,对国内外相关研究进行回顾和展望,有助于把握当前研究的侧重点和薄弱点和相关研究的进一步深化.本文在回顾国内外土地集约利用、耕地集约利用等方面已有研究成果的基础上,立足于我国国情,总结出未来研究展望:①在研究视角上,应着重展开多学科交叉研究,积极开展生态型耕地集约利用研究;②在研究尺度上,应加强多层次、分区域,尤其是大区域的耕地集约利用研究;③在研究内容上,耕地集约利用评价指标体系、驱动机制、时空变化规律和未来变化趋势等应加强研究;④在研究方法上,应进一步强化定量研究,引入GIS、RS等现代技术和数学模型来进行深层次的评价.

Advances and prospects of intensive cultivated land use researches

The intensive cultivated land use concerns to the country food security. This paper was a systematical review and prospect on this field which is necessary and helpful in understanding the focuses, insufficiency and further direction. This paper suggested that (1) in the research perspective, it should emphasize the multi-disciplinary research and conduct positively the research on ecological intensive cultivated land use; (2) in the research scale, it should strengthen the multi-level and sub-regions, especially at the large scale region; (3) in the research content, it should stress the evaluation index system, the drive mechanism, the spatial and temporal change and the future change tendency of intensive cultivated land use; (4) in the research method, it should intensify further the quantitative research and introduce modern technology such as GIS, RS and effective mathematical models into the deep evaluation.
