dc.description.abstract本研究では, 陸面過程モデル(siBuc)を用いてHuBEx-loP期間(1998/5/1-8/31)について中国淮河流域の水・熱収支を計算する.モデル実行時に必要な気象強制力データセットは, GAMRHUBEXプロジェクトの集中観測期間(HUBEX-IOP)で取得された地上気象・水文データから作成された.また日射量に関しては, GMSデータを併用して改善を行った.次に安徽省の農業形態を参考にし, 領域内に存在するすべての農耕地を4つ(1期作水田, 2期作水田, 冬小麦+夏大豆, 冬小麦+夏とうもろこし)に分類した.また中国全土の農業需水量データから淮河流域に関係の深いものを選び出し, 農耕地ごとに生育段階に応じた最適水深, 土壌水分を設定した。数値シミュレーションではこの最適条件を満足するように給水排水量が決定される.灌漑により土壌水分が一定以上に保たれており, かつ日射量が多いため, 北部の畑作地帯においては南部の稲作地帯以上に潜熱が大きいことが明らかになった.ja
dc.description.abstractIn this study, the energy and water budget of Huaihe River Basin in China is calculated by land- surface scheme(SiBUG). The dataset which is used as forcing data for Land Data Assimilation is created by using meteorological and hydrological data obtained during HUBEX-IFO (1998/5/1-8/31). And the diurnal variation of downward short-wave radiation is improved using GMS data.Then based on the agricultural report, all cropland are categorized into four classes (annual paddy, semiannual paddy, wheat + soybean, wheat + maize).According to the water requirement data in the literature, appropriate water level and soil moisture condition is defined depending on the growing stage.In the numerical simulation, irrigation water is supplied or drained to meet this appropriate condition.Due to irrigated water and larger solar radiation, latent heat flux in the northern farmland becomes larger than that in the southern paddy field.ja
