大气中二氧化碳(CO2)浓度水平的增加可能通过蒸散发的变化影响陆地水文过程。应用变入渗能力(VIC)模型,研究了西江流域对co2浓度升高的水文响应。在植物生理研究的基础上,对标准VIC模型进行了修正,加入了对气孔阻力和叶面积增加的植被类型特异性响应的机制描述。引入二氧化碳浓度的动态(月)上升来估计过去20年(1991-2010)二氧化碳增加的历史影响。农田是该地区径流增加响应中最重要的贡献者。在大气二氧化碳浓度加倍的情况下(660 ppm),在基线气候条件下,河流流量可能增加约3%(即21.8毫米/年)。随着环境中二氧化碳的暴露,蒸散量的减少和相关的河流流量的增加预计会偶尔增加洪水的频率和严重程度,并影响森林流域中依赖流量的水生生物群。
Increases in atmospheric carbon dioxide (CO2) concentration levels may affect terrestrial hydrologic processes through changes in evapotranspiration. This study assesses the hydrologic response to the elevated CO2levels for the Xijiang (West River) basin in South China by applying the Variable Infiltration Capacity (VIC) model. The standard VIC model is modified by incorporating a mechanistic description of vegetation-type specific responses of both stomatal resistance and leaf area increase based on plant physiological studies. The dynamic (monthly) rises of CO2concentration are introduced to estimate the historical impacts of increased CO2over the past two decades (1991–2010). The cropland is identified as the most important contributor in the response of streamflow increase for the region. For a doubled atmospheric CO2concentration scenario (660 ppm), the streamflow might rise about 3% (i.e. 21.8 mm/yr) under the baseline climatic conditions. Decreases in evapotranspiration and associated streamflow increases in response to ambient CO2exposures are expected to episodically increase the frequency and severity of flood and affect flow-dependent aquatic biota in forested watersheds.
