农户生计策略变化是农户面对环境变化和自身生计资产所作出的一种理性选择,它直接影响到人类活动与自然环境之间的相互作用,并在很大程度上驱动着农村人地系统的演化。通过对国内外农户生计策略变化研究进展的系统阐述和理论总结,重点阐明农户生计策略内涵、可持续生计框架、生计策略变化对土地利用/覆被变化的影响等方面,提出生计非农化和农业集约化是当前发展中国家和地区农户生计策略变化的主要趋势。最后,结合当前社会经济需求和科学研究需求,展望未来农户生计策略变化的研究趋势。

An Overview of Farmers’Livelihood Strategy Change and Its Effect on Land Use/Cover Change in Developing Countries

Farmers’livelihood strategy change is a rational choice for rural households who are faced with global environmental change and their livelihood capital adjustment.It could affect the interaction between human activity and natural environment,driving the evolution of rural human-environment system to a great extent.Therefore,farmers’livelihood strategy change analysis has been a vital framework to analyze the complex and multi-dimensional relationship between human activity and natural environment in rural areas.After offering a systematical and theoretical review of farmers’livelihood strategy change at home and abroad,this paper summarized the research with an emphasis on the connotation of livelihood strategy change,sustainable livelihood framework,and the influence of farmers’livelihood strategy change on rural land use/cover change(LUCC).Moreover,it is put forward that livelihood non-farm process and agricultural intensification should form the current principal trend and typical characteristics of farmers’livelihood strategy change in most developing countries and regions,rather than livelihood diversification.Finally,the main research directions of farmers’livelihood strategy change in the future are proposed with the present requirements in socioeconomic practice and scientific study in consideration.
