摘　　要：研究目的:以宁夏南部山区为例,研究农业劳动力析出对生态脆弱区耕地撂荒的影响。研究方法:二分类logistic回归模型。研究结果:撂荒耕地面积与劳动力外出数量、时间及农户所拥有的耕地总面积呈正相关;耕地中的坡耕地和旱地首先被撂荒。研究结论:劳动力析出会促使农户撂荒部分质量差的耕地;这种撂荒行为有助于生态环境的自然恢复。The purpose of this paper is to assess the influences production abandonment in ecological sensitive areas by taking of labor emigration from agriculture on cultivated land the mountain area in southern Ningxia as an example. Method employed is binary logistic regression model. The results indicate： （1）the area of production abandoned cultivated land is positively correlated with the amount of labor emigration, the time of emigration and total area of cultivated land owned by farmer households; （2）the slope farmland and dry land will be firstly abandoned. It is concluded that the labor emigration from agriculture can impel the farmer households to abandon partial cultivated land with lower quality, and the abandonment of which will be helpful to the restoration of ecological environment.
