基于不同尺度的中国耕地变化驱动力研究进展

基于国家、区域、省域、市县不同尺度总结归纳中国耕地变化驱动力研究的现状，提出研究中存在的问题。应用文献资料法和对比分析法进行驱动力比较，研究结果表明：中国耕地变化驱动力研究方法以定性定量结合为主；驱动力模型的建立多基于土地利用动态变化模型；国家及区域研究成果较少，省域、市县等小尺度研究成果较多；存在成果分布不均、数据不统一、小尺度研究方法单一、驱动因子选择主观性强以及不同尺度研究成果借鉴性差等问题。研究结果可为在不同尺度中选择耕地变化驱动力及未来耕地利用变化研究提供参考。

Driving Force of Cultivated Land Change in China Based on Different Scales

The research on current situation of driving force of cultivated land change in China was summarized based on the scales of nation, region, province and county, and the existing problems were proposed. The methods of documentation and comparative analysis were adopted in the research. The results showed that both qualitative and quantitative method were used in studying the driving force of cultivated land change in China, and the establishment of driving force model was mainly based on land utilization dynamic change model. The research focused on national and regional scale was less, while the study on small-scale such as province and county was relatively more. The existing problems included uneven distribution of achievements, poor data consistency, simplex research methodology (especially in small-scale research), strong subjectivity in the selection of driving factor and poor compatibility of different research achievements. This research provided reference for cultivated land change driving force selection in different scales and further study on cultivated land utilization change.
