| 摘 要： | 农田水分在"土壤-作物-大气"连续系统内,通过降水、灌溉、土壤蒸发、作物蒸腾、下渗、地下水补给等形式进行着复杂的交换。本文从农田水量平衡原理出发,以农田表层为原型,根据气候条件和作物种植情况,建立农业干旱两层动态模拟模型,模拟农作物生长期农田水分循环过程及土壤墒情信息,为旱情预警预报提供信息。 |
| 关 键 词： | 农田水分 农业干旱 模拟技术 土壤墒情 旱情等级 |

| Abstract: | Ground moisture performs quite complicated exchanges and cycles in the continuous system of "soil-crop-atmosphere",in forms of rainfall,irrigation,soil evaporation,crop evaporation,infiltration,and groundwater supply.According to climate and crop conditions,this paper establishes a dual-level dynamic simulation model on agricultural drought.Farmland surface ground is determined as the prototype,based on ground moisture equilibrium principle.With this model,we are able to simulate ground moisture cycle process,as well as soil moisture information during crop growing period.Information and forecasting on drought emergency is offered. |
| Keywords: | ground moisture agricultural drought simulation technology soil moisture information drought grade |
