- 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。
- Abstract:
- 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.
