This paper aimed to decide the characteristics which can describe the extent of cultivated land abandoning, select items which apply to judge the sustainability of cultivated land abandoning and divide the sustainability patterns of cultivated land abandoning.

2) Abandoned arable land
退耕撂荒地
1.
In order to understand dynamics of soil water-stable aggregates along chronosequences and relationship with soil physico-chemical properties on abandoned arable land in eroded hilly loess plateau,11 arable old land with different ages after being abandoned in Zhifanggou catchment were studied systematically through the approach of substituting the temporal serial with spatial serial.
研究了侵蚀环境退耕撂荒地生态恢复过程中水稳性团聚体的变化规律及其与土壤养分状况及土壤微生物量的关系,结果表明,侵蚀环境退耕撂荒地土壤水稳性团聚体含量迅速提高,在退耕撂荒的第一个10年,水稳性团聚体增大约253。

In order to understand dynamics of soil water-stable aggregates along chronosequences and relationship with soil physico-chemical properties on abandoned arable land in Eroded Hilly Loess Plateau,11 arable old land with different ages after being abandoned in Zhifanggou Catchment were studied systematically through the approach of substituting the temporal serial with spatial seri- al.
本文研究了侵蚀环境退耕撂荒地生态恢复过程中水稳性团聚体的变化规律及其与土壤养分状况及土壤微生物量的关系,结果表明,侵蚀环境退耕撂荒地土壤水稳性团聚体含量迅速提高,在退耕撂荒的第一个10年,水稳性团聚体增大约253。
3) 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。
4) Abandoned land
撂荒地
1.
Species diversity of plant communities on abandoned land in the Guandi Mountains,Shanxi;
山西关帝山撂荒地植物群落物种多样性研究(简报)
2.
Based on the dataset of 52 plots investigated from the field,the interspecific relationship among 31 dominant populations of the communities of abandoned land in Guandi Mountains,Shanxi was studied by using χ2 test for 2×2 contingency tables,Pearson s correlation coefficient test and Spearman s rank correlation coefficient test,respectively.
根据野外52个样方的调查数据,运用2×2列联表的χ2检验、Pearson相关系数检验和Spearman秩相关系数检验研究了山西关帝山撂荒地植被31个建群种和优势种种间关联和相关关系。
5) wasteland problem
农地撂荒
1.
Focusing on the wasteland problem,this paper points out that the essential reason of wasteland problem lies in the lower return of agricultural investment.
作者针对我国当前的农地撂荒问题,指出农地撂荒的根源在于农地投资的比较收益低下。
6) deserted farmland
