摘要
本文采用农业系统工程方法与农业气候分析方法相结合的途径,对黑龙江省海伦县的农业气象灾害类型及主要作物的受害减产率进行了定量研究,并建立了寻求作物抗灾稳产合理种植比例的数学模型及用计算机进行了优化处理。在此基础上,提出了针对不同情况所应采用的各种决策方案。本文的研究结果。经过用历史资料的效果检验后,已提供给当地生产领导部门参考使用。
The combination of methods of agricultural system engineering and traditional agricultural climatic analysis is used for studying the types of agricultural climatic disaster and decreased rates of crop yields caused by the hit of natural adversity in Hailun county,Heilongjiang province.The mathematics model of rational planting ratio in order to fight disaster and get stable yields has been found.Optimization treatment was computerized.Basing on the results mentioned above,several strategic plans aiming at different conditions have been suggested.After the examination of effectiveness with historical data,the results of the study have been recommended to the local production leadership departments.
