区域农业干旱模型的建立与应用
Establishment and Application of Agricultural Drought Model
【摘要】 本研究采用调查、实验、模型相结合方法,建立了区域农业干旱模型。并将其应用于区域农业干旱评价、监测及对策分析等方面。研究结果表明:气象干旱指标P/E(p-降水量,E-潜在蒸发量)不能准确表达农业干旱状况,本研究所建立的农业干旱模型经验证有广泛的适用性和准确性,对农业干旱的评价、监测与实际相符,对农业于旱理论与实践都具有一定价值。
【Abstract】 Agricultural drought model contains sontains 5 sub-models agricultural drought index model, watercirculation model, wrter reguirement model,forest water balance model and cropance model and crop productive POtentialities’model. The inspected regions included Liaohe basin, Hailuanhe basin, Huaihe baisn, Huanghe basin andChangjing basin. The results showed thtt agricultural drought model was compatible and precision, andcould be used to evaluate and monitor agricultural drought make strategies of agricultural drought andestimate crop yield.
