Land Use and Watershed Health in the United States
在全美流域尺度上实证分析土地利用对水质和水生生态系统的影响，发现集约农业和城市发展显著影响常规水污染，交通和采矿用地则显著影响有毒水污染，并探讨了结果对水质量交易政策设计的启示。
<i>This national-scale, watershed-level analysis provides an empirical assessment of land use impacts on water quality and aquatic ecosystems in the United States. Results suggest that the level of conventional water pollution in a watershed is significantly affected by the amount of land allocated to intensive agriculture and urban development, while the level of toxic water pollution is significantly affected by the amount of land allocated to transportation and mining. We examine the relationship between land use, water quality, and aquatic species extinction and discuss the implications of the results for the design and implementation of the water quality trading policy.</i>
