为了分析中国塔里木盆地沙漠绿洲的水资源转化消耗规律,建立了绿洲水热耦合平衡模型。该模型以年灌溉引水量和降水量之和作为绿洲年可供水量,采用傅抱璞公式将Budyko假设推广。以塔里木盆地绿洲的5个大型绿洲1971—2004年的年降水、灌溉引水、径流和潜在蒸散发资料,验证了水热耦合平衡关系。分析了年蒸散发规律和土地利用变化对模型参数的影响。拟合了阿克苏河绿洲的估算模型参数的经验公式。
In order to analyze the law of water resources conversion and consumption in the desert oasis of Tarim Basin in China, an oasis hydrothermal-coupled equilibrium model was established. The model uses the sum of annual water diversion and precipitation as the annual water availability of oasis, and uses the formula of Fu Baopu to popularize the Budyko assumption. The annual precipitation, irrigation diversion, runoff and potential evapotranspiration data from 5 large oases in the oasis of Tarim Basin from 1971 to 2004 were used to verify the water-heat balance relationship. The effects of annual evapotranspiration and land use change on model parameters were analyzed. The empirical formula of the estimated model parameters of Aksu River oasis is fitted.
