Tallgrass prairie has been reduced to a fraction of its original extent, due to rapid conversion to other land use types, especially agricultural and urban. Restoration is a relatively new process to convert agricultural land back to communities dominated by native vegetation. We used a differential equations compartmental model to quantify changes between land use types, incorporating the impact of human population within the Midwestern tallgrass prairie ecosystem. We considered transitions between native prairie, prairie restored through the Conservation Reserve Program (CRP), agricultural, and urban land. We used historical data to determine parameter ranges. Sensitivity analyses emphasize the importance of increasing incentives for CRP enrollment as a means to restoring the tallgrass prairie ecosystem.

高草草原生态系统内的土地利用动态：保护储备计划（CRP）的案例

由于迅速转变为其他土地利用类型，尤其是农业和城市土地，高草草原已经减少到其原始范围的一小部分。恢复是一个相对较新的过程，可以将农业用地转化为以原生植被为主的社区。我们使用微分方程分区模型来量化土地利用类型之间的变化，并纳入中西部高草草原生态系统中人口的影响。我们考虑了原始草原，通过保护储藏计划（CRP）恢复的草原，农业和城市土地之间的过渡。我们使用历史数据来确定参数范围。敏感性分析强调了增加CRP入学激励的重要性，作为恢复高草草原生态系统的一种手段。
