农地多功能权衡与协同研究进展与趋势

Literature Review on Trade-offs and Synergies of Multifunctional Agricultural Land

采用文献资料法、比较法、归纳演绎法系统梳理国内外关于农地多功能权衡与协同作用的研究文献,揭示其研究进展和未来研究趋势。研究发现:(1)从农地多功能权衡与协同单一时间尺度研究转向时空动态变化研究;从省级、市级、区县级、街道级和空间格网尺度等单一尺度研究,逐渐转向多尺度研究;从线性相关关系研究逐渐转向非线性关系研究。(2)与国外研究相比,国内研究多侧重划分功能分类,构建评价指标体系,利用统计数据开展省级、市级、区县级等单一行政尺度研究,近来利用空间数据开展栅格尺度的研究较多,且开始重视行政尺度或栅格尺度或者两个尺度结合的多尺度研究,试图揭示权衡与协同的多尺度效应,但尺度之间的作用机制研究较少。国外研究集中于更小尺度考虑地方情景的农地多功能权衡与协同形成机制、驱动因素,关注权衡与协同研究在空间规划、管理政策制定中的应用。研究结论:该研究结果可以为农地多功能权衡与协同领域的进一步深入研究提供依据,也可指导农地多功能空间管理和农田建设实践,从而实现农地利用经济、社会和生态的可持续性。

This paper adopts the methods of literature,comparison and induction-deduction to systematically review the research literature on multifunctional trade-offs and synergy of agricultural land at home and abroad,and reveal its research progress and future research trends.The study found:(1)the focus of current research is characterized by a transition from single time scale to spatial-temporal changes;from single-scale research at the provincial,municipal,district and county,street,and spatial grid scales to multi-scale research;from linear correlation research to nonlinear relationship research.(2)Compared with international researches,domestic researches focus more on dividing functional classifications,constructing an evaluation index system,and using statistical data to conduct research on a single administrative scale at the provincial,municipal,district and county levels.Recently,more researches on the grid scale have been conducted using spatial data,and they have begun to focus on multi-scale researches at the administrative scale or the grid scale or the combination of both scales,trying to reveal the multi-scale effects of trade-offs and synergies.The mechanisms of interaction between scales,however,have been less studied.International researches focus on the formation mechanism and driving factors of trade-offs and synergies of multifunctional agricultural land considering local scenarios on a smaller scale,and pay attention to the application of trade-offs and synergies research in spatial planning and management policy formulation.The research results can provide a basis for further in-depth research in the field of multifunctional trade-offs and synergies in agricultural land,and can also guide the practice of multifunctional spatial management of agricultural land and farmland construction,so as to realize the economic,social and ecological sustainability of agricultural land.
