基于宁夏回族自治区南部旱作农区干旱气候特征和作物种群干旱适应性 ,借助农业系统工程原理和方法进行优化设计 ,组建了不同生态类型地区的抗旱应变种植制度决策系统。在综合考虑各种干旱发生频率及其对作物产量影响程度的基础上 ,种植制度优化模式包括了随机型和确定型两种决策方案。系统分析和生产验证表明 ,优化方案可产生显著的经济和生态效益
Based on the characteristics of arid climate and the adaptive adaptability of crop population to drought in the southern part of Ningxia Hui Autonomous Region, the optimal design of agriculture system engineering principles and methods was used to establish the decision-making system of drought-resistant planting system in different ecotypes. Based on a comprehensive consideration of the frequency of occurrence of various droughts and their impact on crop yield, the optimization model of cropping system includes two kinds of decision-making schemes: stochastic and deterministic. System analysis and production verification show that the optimization program can produce significant economic and ecological benefits
