Crop selection and implications for profits and wind erosion in a semi-arid environment
模拟了德克萨斯州南部高原四种旱作种植制度在不同价格和随机天气下的利润分布，发现生产者风险厌恶程度、价格预期和贴现率影响最优轮作选择，进而影响长期年均风蚀土壤流失。
A daily crop growth simulation model was applied to four dry land cropping systems to estimate the profit distributions for each of four price series under stochastic weather conditions on the Southern High Plains of Texas. Stochastic dominance with respect to a function was utilized to rank each crop rotation for different risk-averse intervals. Solutions from the model indicate that long-term average annual soil loss due to wind erosion was a function of the producer's risk aversion, price expectation, and discount rate which affect the optimal crop rotation selection.
