英文文献摘要：
Participation in the Conservation Reserve Program (CRP) is associated with a number of farm and operator characteristics. But casual observation suggests that socioeconomic status is also correlated with program enrollment outcomes. This study examines the relationship between county-level socioeconomic status and participation patterns in CRP, while controlling for other factors that typically impact program enrollment. Result suggest that farms in low socioeconomic status counties are less likely to participate, enroll a smaller share of their land, and receive less per acre enrolled.

参与保护保护区计划(CRP)与一些农场和经营者的特点有关。但偶然的观察表明，社会经济地位也与项目的报名结果相关。本研究调查了县级社会经济地位和参与CRP的模式之间的关系，同时控制了其他通常影响项目登记的因素。结果显示，社会经济地位较低县的农户参与农户活动的可能性较低，登记的土地份额较小，每英亩获得的农户收入也较低。
