摘要
对蒸散估算的尺度放大是研究的热点问题。选择有大量数据积累的鄂尔多斯高原皇甫川流域为研究区,利用点面结合的方式对数据进行补测,以生物学为基础,建立了植物蒸腾和植被蒸散模型,经验证,模拟效果较好。从而在植物叶片-个体-群落-景观尺度上实现了转换,为实现好的蒸散模拟提供了方法。
Upscaling of evapotranspiration is a hot topic.The study area is located in the Huangfuchuan watershed of Ordos Plateau which had been intensively studied in the past.In order to develop models,the data were collected complementarily in a integrative way of partial and whole.Plant transpiration and vegetation evapotranspiration models were developed based on biology.The verification is at an acceptable level of uncertainty.Scaling of leaf-individual-community-landscape was realized and a good method estimating evapotranspiration was provided.
