6) abandonment of the arable land
弃耕撂荒
1.
Based on the cost-income datum(1980～2002) of farm product and the China Agricultural Yearbook,taking these main crops in the progress of the arable land use as a study case,this paper studied the characters and its driving force for the annual changes of the degree of intensity,the sowing area and the abandonment of the arable land.
结果表明:近20多年来,中国农地利用的集约度与总播种面积均有不断提高与扩大的总体趋势,但在扩大过程中却有三次显著下降变化,在集约度下降时期(1984~1986年、1992~1993年、1997~1999年),农作物播种面积明显缩小,农地弃耕撂荒现象开始显著增加;导致这些变化的根本原因同农地利用过程中成本要求与土地要素纯收益的变化密切相关,但在时间响应上,由于农户要经过一个“观望-权衡-行动”的响应过程,从而往往滞后1~3年。
