美国的就业和土地利用：横截面和短期趋势揭示了第96子午线的重要性
Employment and Land Use in the United States: cross-sectional and short-term Trends reveal the Importance of the 96th Meridian
摘要：
经济发展的普遍趋势是从农业经济转向制造业经济，最后转向服务业经济。由于与每个部门有关的就业类型影响自然资源的使用，这一全球趋势可能表现在可预测的土地使用过渡中。我们将这些与城市、农业和自然土地的变化联系起来。我们发现，经济转型是普遍存在于大多数国家和跨国家。农业用地扩展到自然区域，但最终被城市所取代。将部门与土地覆盖联系起来，我们看到服务业就业的增加与城市地区的增长之间存在着密切的关系。然而，我们发现，无论是大农业区和大自然区也发生高服务就业。最后，我们测试了第100子午线是否与土地覆被和经济部门之间的可预测关系有关，并发现了强有力的结果，表明东部和西部的不同发展模式。
英文摘要：
A pervasive trend in economic development is the shift from agricultural to manufacturing and finally to service economies. Because the type of employment associated with each sector influences natural resource use this global trend may manifest itself in predictable land use transitions. We relate these to changes in urban, agricultural, and natural lands. We find that the economic transition is common in most counties and across counties. Agricultural land expands to natural areas but is eventually replaced by urban. Relating sectors to land cover, we see a strong relationship between increases in service employment and the growth of urban areas. However, we find that both large agricultural areas and large natural areas also occur with high service employment. Finally, we test if the 100th Meridian is associated with predictable relationships between land cover and economic sectors and find strong results that suggest different development patterns in the East and West.
