论文摘要
经济发展的普遍趋势是从农业到制造业，再到服务经济体的转变。因为与每个部门相关的就业类型会影响自然资源使用，因此这种全球趋势可能会在可预测的土地使用过渡中表现出来。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，经济转变在大多数县和整个县都是普遍的。农业土地扩展到自然地区，但最终被城市所取代。与土地覆盖的部门有关，我们看到服务就业的增加与城市地区的增长之间存在牢固的关系。但是，我们发现大型农业地区和大型自然地区都在高服务就业中出现。最后，我们测试了第100个子午线是否与土地覆盖与经济部门之间的可预测关系相关联，并找到了强大的结果，这些结果表明了东部和西部的不同发展模式。
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.
