摘　　要：当农地利用的纯收益逐年降低,且其后出现农地利用集约度降低和相应农作物播种面积减少甚至农地的弃耕撂荒现象时,就出现了农地的边际化现象。农地在边际化的进程中会经历不同的边际化阶段,不同阶段的边际化程度不同,可分为初始边际化、中期边际化、完全边际化。本文依托湖北省通城县的实地调查资料结合统计资料,研究了通城县的两种代表性农地——水田和旱地的边际化进程。结果表明:同种类型的农地的边际化程度随着时间的推移而变化,不同类型农地的边际化进程也有差别。在通城县,旱地的边际化进程快于水田。一般来说,边际化会导致相应农作物的播种面积减少,而完全边际化会直接导致农地的弃耕撂荒。When the net income of arable land use reduces every year, and after that, the degree of intensity and the planted area reduce too, even more abandonment of arable land take place. We can judge that there is marginalization phenomenon in the land use. The course of the marginalization of arable land use can be distinguished to different phase, they are preliminary marginalization, metaphase marginalization and absolute marginalization. This paper is case of Tongcheng county Hubei province, basing on the data of coming from every farmer and agricultural yearbooks. We have studied the marginalization course of two kinds of arable land. The results indicate that the marginalization degree of same kind of arable land will be change in different time. The course of marginalization of different arable land use is different. In Tongcheng county, the course of dry land is faster than the paddy field. In a general way, the marginalization of arable land can result in the sowing area of the crop shrink evidently and the absolute marginalization can result in the abandonment of arable land.
