论文从研究视角、研究内容、研究方法和手段、数据获取4个方面对农户层面土地利用变化研究进行了概括。并归纳出目前研究的几个特点:①研究较为关注热点地区;②多将农户层面土地利用变化的驱动力归因于人口增长所导致的生计压力以及与之相关的农业扩张;⑧研究逐步从单纯关注用途变更转向对用途变更和土地利用集约度变化并重;④在手段和方法上趋于多样化并趋向于综合使用多种方法;⑤土地利用主体决策行为对于土地利用变化影响得到重视;⑥在分析数据的获取上,问卷调查成为主导方式,但越来越多的研究开始尝试将问卷调查和“3S”技术相结合。最后总结了已有研究存在的问题,并探讨了今后农户层面土地利用变化研究发展的方向。
This paper gives a comprehensive description of the researches of land use change at farm household level from the four aspects of investigation respect,research content,study method and data collecting means, and summarizes the features of the researches on land use change at farm household level.The main features are: (1)Most of the researches give notices on the land use change of hot regions,particularly on the tropical-forest area. (2)Lots of the researches attribute the land use changes on the pressure of subsistence to the population growth and the agriculture expansion which is also related with the population growth. (3)The attention of researches is being converted from land use type change to both land use conversion and land use intensity change. (4)More and more methods are applied by the researches of land use change at farm household level and integrated methods are appreciated by more and more studies. (5)The impacts of the decision-making behaviors of land users or managers on land use change are emphasized by most researches. (6)The social survey using questionnaires becomes a main tool of data collecting,but more and more investigations combine the social survey using questionnaires and the techniques of "3S" to get the data on land use change and its driving forces at farm household level ,and devote to connecting the social survey data and the remote sensing data. Although much progress has been made in theory and practice of land use change research at farm household level,and some important results have been obtained ,there still have certain problems in previous researches.These problems go as follows:the results of land use change study at farm household level can not be easily applied to other microeconomic agents,the results in one region should be much carefully applied to any other regions, the relation and interaction between different hierarchical data have been neglected,the acquiring cost of data which contains economic data and its corresponding sp
