中文摘要：

2004-2010年中央的一号文件都是关于＂三农＂问题。中国农业发展历史悠久,在世界具有独特性。河南省作为全国第一人口、农业、粮食、粮食加工大省,在全国农田系统研究中更具代表性和特殊性。已有文献从4个方面对农田系统开展研究：第一,地形视角,分为山地、平原区、丘陵区农田系统;第二,研究内容方面,施肥、养分及其流失,化感作用,碳平衡,受污农田,生物多样性,LUCC变化;第三,耕作方式视角,可划分为轮作、间作、免耕等农田系统类型;第四,研究方法上,有经济学方法、生态学方法、物理学方法、3S技术方法等。目前成果尚存在以下不足：第一,对传统农区关注不够;第二,3S技术应用范围急需扩展;第三,田野调查方法运用不足;第四,微观视角研究欠缺。并且,在农田与环境相互作用机理、农田区位理论、农田结构及其动态分化研究、研究方法的综合运用、不同尺度农田系统运行模式的总结、中国农田系统研究等方面尚待加强。进一步提出了农田的发展趋势：数量进一步减少;产出逐渐提高、但弱势地位难以改观;产出差异扩大;发展模式更趋多元化;集聚经济将重现活力;影响因素更趋复杂。

英文摘要：

The first documents which central government issues are on the three Rural-related Problems from 2004 to 2010.China is unique,and has a long history in agriculture,especially Henan Province which is more representative,specificity,and is first in population,agriculture,food,food processing.Farmland system has been studied from the following four aspects： the first,terrain which are divided into mountains,plains,hills area;the second,research contents which are divided into fertilization,nutrient and its loss,pest and disease control research,allelopathy,carbon balance,contaminated farmland,biological diversity,LUCC change;the third,farming methods which are divided into crop rotation,intercropping,free-tillage;the fourth,research methods which are divided into economic approach,ecological method,physical method,3S technology.There are deficiencies： the first,traditional farming areas have been gotten insufficient attentions;the second,3S technology would need to expand the scope of technology applications;the third,methods of field survey have been gotten insufficient use;the fourth,micro-perspective was lack.Besides,the following can be strengthened in the mechanism of interactions between farmland and environment,farmland location theory,farmland structure and dynamics of change,the integrated use of research methods,summary of different scales of farmland system operating mode,research of China＇s farmland system and so on.Further,the trends of farmland development are put forward： the number will be further reduced;the output is going to gradually increased,but the weak position will be unlikely to improve;the differences in output would be expanded;more models may be come forth;agglomeration economy will be revitalized;the factors are to more complex.
