摘要:

国内外耕地粮食生产能力研究较多关注耕地生产能力及其耕地生产能力刚性损失的研究,而缺乏对耕地生产能力隐性损失的深入研究。本文对农户土地利用行为与粮食生产能力的区域尺度和时间尺度的层次性,以及农户土地利用行为对粮食生产能力隐性损失的关系进行表述,而后从农户土地利用、耕地集约利用和耕地生产能力3个方面的国内外研究进展进行综述,进而将耕地生产潜力的实现差异性和农户土地利用差异有机结合,构建基于农户土地利用行为的耕地生产能力研究的框架体系、探讨相关研究内容及研究方法。在研究内容上,要从农户耕地集约利用时空差异规律入手,分析集约利用差异对耕地生产能力及其实现程度的影响,分析不同区域耕地生产能力的隐性损失强度及其时间空间差异特征,并构建基于农户土地利用-作物生长-生产能力影响的模型。此外,基于农户土地利用的耕地生产能力研究,不仅要借助传统的学科方法,还要结合应用遥感信息识别技术、地理空间分析技术、空间定位技术等,在研究方法和数据采集技术方面实现突破。

Abstract:

Research on grain production capacity in China mostly put emphasis on rigid loss, and neglects elastic loss of grain productivity, especially that from the perspective of farm household land use behavior. At first, the paper elaborates, at different regional scales and temporal levels, the hierarchy of farm household land use and grain production capacity, and the impacts of farm household land use on the elastic loss of grain production capacity. Then, the research progresses in farm household land use, cultivated land intensive use and farmland productivity. We put forward a research framework of grain productivity on the basis of farm household land use and discuss the related study contents and methods. The study on the process, state, and mechanism of farm household land use behavior is the important basis for grain production capacity elastic loss evaluation. We need to explore the spatial and temporal changes of cultivated land intensive use of farm households and the impacts of the difference in intensity on farmland productivity, to analyze the intensity and the difference of elastic loss of grain production capacity at different spatial and temporal scales, and to set up the model of farm household land use-crop growth-the effects on grain production capacity. The researches include the following five aspects: (1) to analyze the mechanism of household land use, (2) to establish a farm household land use decision-making model, (3) to discuss the difference in household land use, (4) to probe into the impacts of farm household land use on grain productivity, (5) to study the change of arable land intensive use and its effects on grain production capacity. Moreover, we need to apply multidisciplinary methods to study on the elastic loss of grain production capacity, such as traditional study method in combination with remote sense information identification, GIS and spatial orientation, and we also need to make some advances in data collection.
