基于农户尺度的山区耕地撂荒影响因素分析

Reasons of Cultivated Land Abandonment in Hilly Areas Based on Perspective of Farmers

近年来,受到多种因素的影响,我国各地均出现了不同程度的耕地撂荒现象,使得本已尖锐的人地矛盾更加突出.本文基于农户尺度,以重庆市东部山区的3个区县为例,采用参与式农户评估法(PRA)对12个典型村进行农户调查,得到有效问卷975份,利用二分类Logistic回归模型分析研究区农户耕地撂荒的影响因素.研究结果表明:1)研究区内耕地撂荒现象大量存在,撂荒耕地总面积占到研究区耕地总面积的21%;2)经济因素是影响耕地撂荒的重要原因;3)丘陵山区的耕地地块破碎、区位条件是影响耕地撂荒的重要原因.

In recent years,the phenomenon of cultivated land abandonment has become a great concern in academia,as it makes the already tense contradiction between land use and people more prominent.This paper analyzed the reasons of cultivated land abandonment under the perspective of farmers.The method of participatory rural appraisal（PRA）was adopted in this study.Household survey was made at three districts and counties in east Chongqing and 975 valid questionnaires were obtained.A binary logistic regression model was employed to explain the reasons of cultivated land abandonment.The results indicated that：（1）Cultivated land abandonment was found to exist extensively throughout the area.（2）Economic factors were the main reason of cultivated land abandonment.（3）The positional condition of cultivated land impacts cultivated land abandonment in hilly area.
