作物蒸散量计算模型研究进展

Advances in Calculation Models of Crop Water Evapotranspiration

从作物需水量与蒸散量关系出发,对目前国内外计算作物蒸散量的不同模型,包括单一模型、互补相关模型、红外遥感模型、SWAP模型等进行了总结,初步探讨了这些模型各自的优势和存在的问题,并预测了作物蒸散量计算模型的发展趋势。

In this paper,the relationship between crop water demand and evapotranspiration was discussed. The different models for calculating crop water evapotranspiration at home and abroad,including single model,complementary correlation model,infrared remote sensing model,and SWAP model were summarized. The advantages and existing problems of these models were preliminarily discussed,and the development trend for calculation models of crop evapotranspiration was predicted.
