Steady‐State Solutions to Soil Salinity Optimization Problems
构建了一个考虑盐分动态积累的利润最大化模型，计算加州两地区脐橙的稳态最优用水量和土壤盐分，发现多数情况下维持最高产量的用水量是最优的。
Abstract This paper is concerned with the profit‐maximizing choice of water quantities given the choice of crop and water quality but taking into account the dynamics of salt accumulation over time. The optimization model formulated in this paper is based on a detailed representation of the salt transport process in soils but assumes known or average rainfall levels. Optimal water quantities and soil salinities in steady state were calculated for navel oranges in two areas of California. Water applications sufficient to maintain maximum yields were found to be optimal in many cases.
