中国农地细碎化问题研究进展

Review on the Research of Farmland Fragmentation in China

为掌握中国农地细碎化问题研究进展,论文采用概括和比较分析的手段,从农地细碎化的概念内涵、主要研究内容、研究方法等方面对农地细碎化研究进行梳理和概括。归纳出已有研究的几个特点:①农地细碎化的内涵较为清晰且已经得到了广泛认可,但对细碎化程度的衡量方法还需进一步深入;②目前的中国农地细碎化研究主要集中在细碎化成因及其对农业生产的影响方面,以其负面影响的研究最为丰富;③农地细碎化与农地流转、土地整理的关系引起了研究的重视,但是目前主要集中于农地流转对减轻细碎化程度的探讨,土地整理对细碎化作用的研究十分缺乏;④农地细碎化研究涉及的主要是回归分析、生产函数模型等经济学研究方法,利用地理空间分析方法和景观生态学方法探讨农地细碎化问题的研究尚未见报道。最后探讨了还需要进一步深入研究的内容。

For the purpose of keeping abreast the development of farmland fragmentation analysis in China,this paper gives a comprehensive description of the research on farmland fragmentation by using the summary and comparison analysis approaches.The analysis is organized from three aspects flowed as the definition of farmland fragmentation,the main fields concerned by farmland fragmentation and the measurement method.The main features about the research of farmland fragmentation go as follows.Firstly,the connotation of farmland fragmentation is clear and has been widely recognized,but the measurement method for the degree of fragmentation still needs further study.Secondly,the farmland fragmentation research in China mainly focuses on the causes and the effects on agricultural production.Among them,the research on negative effects of agricultural production is most sufficient.Furthermore,the relationship between farmland fragmentation and land consolidation attracted more attention.The research on the relationship between farmland fragmentation and land transfer is quite inadequate.The last but not the least,the study on land fragmentation mainly uses economic research methods,such as production function and regression analysis.Geographical spatial analysis method and the method of landscape ecology have not been used in the research.Besides,some suggestions on further studies of decoupling are put forward in this paper.These suggestions include giving more concern on comparative study of different areas based on different economic and social background;strengthening the study on relationship between farmland fragmentation and comprehensive regulation of rural land;in order to expand the research angle and research content,trying to combine the discipline of geography with landscape ecology,especially using the methods of RS and GIS in farmland fragmentation.
