摘要:
[目的]综述耕地数量变化的驱动因子与驱动机理,为未来丰富相关研究以及针对性地制定耕地保护对策提供参考。[方法]文章主要应用了文献分析法、分类统计法和比较分析法。[结果](1)耕地数量变化的驱动因子主要包括自然因子和社会经济因子,地形、气候等自然因子往往在较长时间内发挥作用,经济状况、区位条件等社会经济因子在短期内对耕地变化的影响较大,国家政策是特殊的社会经济因子。(2)自然因子和社会经济因子分别通过改变土地生产潜力、影响耕地和建设用地平衡来驱动耕地数量变化,社会经济因子中的政策因子通过强化或减弱土地某项功能对耕地变化产生影响。(3)自然因子对耕地数量变化的驱动作用在快速城镇化地区、粮食主产地区和生态脆弱地区依次增强,社会经济因子的驱动作用依次减弱,政策因子是所有区域耕地数量变化的主要驱动因子。(4)快速城镇化地区、粮食主产地区和生态脆弱地区的耕地数量变化分别主要受到建设占用、粮食生产和经济发展压力、自然条件限制及退耕还林驱动。[结论]探究耕地变化的驱动因子和驱动机理是提高耕地管理效率的有效途径,未来研究应当向全面分析耕地变化内涵,定量研究政策因子,衔接耕地保护对策制定等方向发展。

Abstract:
The purpose of this paper is to review the driving factors and driving mechanism of cultivated land quantity change, in order to enrich relevant researches and provide references for formulating cultivated land protection policies purposefully in the future. We adopted the methods of literature analysis, classified statistic and comparative analysis. The results of this paper were showed as follows. (1) Driving factors of cultivated land quantity change could be divided into natural factors and socio economic factors. Natural factors often affected the long term change of cultivated land quantity, such as topography, climate, water resource, soil and so on. Socio economic factors had great influence on cultivated land quantity change in a short term, such as economic development, location conditions, population scale and so on. In addition, national policy was a special socio economic factor. (2) Natural factors and socio economic factors drived the cultivated land quantity change by changing the potential land productive potential and affecting the balance of cultivated land and construction land, respectively. As a special socio economic factor, policy factors impact on the cultivated land quantity change by strengthening or weakening certain land functions. (3) In this paper, we summarized the differences of driving factors and driving mechanism of cultivated land quantity change in rapidly urbanizing regions, major grain producing areas and vulnerable ecological regions. In the above three regions, the driving effect of natural factors on cultivated land quantity change enhanced in turn, while that of socio economic factors weakened in turn. Policy factors played an important role on cultivated land quantity change in all regions. (4) In rapidly urbanizing regions, major grain producing areas and vulnerable ecological regions, the main driving factors of cultivated land quantity change included that cultivated land occupied by construction, the contradiction between grain production and economic development, the limitation of natural conditions and grain for green program. In conclusions, exploring the driving factors and driving mechanism of cultivated land quantity change is an effective way to improve the cultivated land management efficiency. According to the above results, in the future, we should pay more attention to cultivated land quality change and cultivated land ecological change at first, so as to enrich the intension of cultivated land change. Secondly, relevant researches need to seek more methods of land management policy quantification, so that the land management policy can be included in quantitative models. Thirdly, it is important to link up researches with the policies formulation of land management, make researches serve land management more efficiently.
