Cost‐Effective Targeting of Land Retirement to Improve Water Quality with Endogenous Sediment Deposition Coefficients
构建了一个结合空间、生物物理属性、水文模型和经济模型的框架，用于识别应纳入保护储备增强计划的农田。以伊利诺伊州某流域为例，发现应选择靠近水体的高坡度土地休耕，且边际价值租金方案比基于生产力的方案成本低39%。
An integrated framework that combines spatial and biophysical attributes of land with a hydrological model and an economic model is developed to identify cropland for enrollment in the Conservation Reserve Enhancement Program. Sediment deposition coefficients are determined endogenously depending on the land‐use decisions on other land parcels. Application of this framework to a watershed in Illinois demonstrates that highly sloping land adjacent to water bodies should be selected for retirement. A marginal value rental payment scheme can achieve program goals of 20% sediment abatement at 39% lower cost than a productivity‐based rental scheme.
