摘要
根据农田水量平衡原理 ,建立了灌溉条件下的干旱模拟模型。以湖北省某灌区旱作物棉花为例 ,模拟该灌区 17年来棉花发生干旱的情况 ,根据模拟结果 ,通过对比分析了该灌区自然条件下和灌溉条件下的棉花、晚稻产量与干旱所造成的损失 。
Based on the principle of water balance on farmland, a simulation model for agricultural drought under condition of irrigation is proposed. Case study of cotton cropping area in an irrigation district in Hubei Province is conducted with a series of cotton drought data in 17 years. Through comparison between the yield and loss of cotton under conditions of with and without irrigation, the irrigation benefit of the district is assessed.
