本文以白草沟小流域为例,应用系统工程原理进行系统诊断,建立了多目标数学规划模型,在满足目标函数,即经济纯收入最大、土壤流失量最小、投资最少、生物量最大的情况下,求出模型的最优解。
Taking Baicaogou small watershed as an example, this paper uses system engineering principles to diagnose the system and establishes a multi-objective mathematical programming model. When the objective function is satisfied, ie the net economic income is the largest, the soil loss is the smallest, the investment is the least and the biomass is the largest Under, find the optimal solution of the model.
