Multiattribute Assessment of Alternative Cropping Systems
从盈利和环境两个角度评估了美国中西部72种玉米、大豆和苜蓿草种植系统,发现低投入、少耕的玉米-大豆轮作在高产土壤上,以及低投入、少耕的连作玉米在低产土壤上,无论优先考虑利润还是环境都是优选方案。
Abstract Multiattribute rankings of seventy‐two alternative midwestern cropping systems involving corn, soybeans, and alfalfa hay are analyzed from profitability and environmental quality perspectives. Environmental consequences are simulated using EPIC and GLEAMS, and profitability is based on budget analysis. Results are analyzed using an algorithm based on multiattribute decision theory. A corn‐soybean rotation using low input levels and minimum tillage on high‐productivity soil, and continuous corn using low input levels and minimum tillage on low‐productivity soil are in the preferred set regardless of whether profits or preserving the environment is the first priority for the decision maker.
