摘要: In this study, ten bioenergy crop rotations (corn, corn-stover, sorghum, soybean, corn-soybean, corn-soybean-canola, corn-stover-soybean, miscanthus, switchgrass, and sorghum-soybean) were selected based on local stakeholder (economically motivated) regulator (environmentally preferences. These crops implemented diverse landscapes (agricultural, marginal, agricultural plus marginal lands) one at time for 17 years using a SWAT model of the Saginaw River Watershed in Michigan. The evaluated 100 percent, 50 zero percent weight assigned to both stakeholders’ regulators’ preferences analytic hierarchy process (AHP), an optimization decision-making technique that aims satisfy multiple conflicting objectives. corn-soybean-canola rotation was all economic benefits (stakeholders’ preferences). Meanwhile, perennial grasses (miscanthus switchgrass) environmental (regulators’ preferences), because they maintain permanent cover, require fewer inputs than traditional row crops, are less management intensive. When implementing lands, pollution generation greatly increased field level, indicating these lands likely not viable production meet potential future renewable energy demand.
