中文摘要: 针对现存水 -碳耦合模型中存在机理复杂、结构不平衡、不确定性较大、资料需求难以满足等问题,根据非线性水文循环模拟理论的 从复杂现象中,寻找简单规律 的理念,基于非线性水文循环理论构建具有一定物理机理和精度的水 -碳耦合模拟方法。采用American-Flux的Duke站点和白洋淀上游的崇陵试验流域小区的试验数据,在点尺度和小区尺度对构建模型的精度加以验证,结果显示,基于非线性理论的耦合模型能够更加合理和准确的模拟水文循环中蒸散发量和土壤含水量的变化过程;最后采用该模型估算了温室气体排放量对水文循环要素的影响,在二氧化碳浓度加倍情景下,试验小区径流深增加0.5%;平均土壤含水量增加1.2%;蒸散发量减少4.9%。综合表明,构建模型达到了采用简单方法解决复杂问题的效果。
英文摘要: The current water-carbon coupling models have several issues such as complex mechanisms,unbalanced structure,large uncertainty,and difficulty to meet the information needs.According to the concept offrom the complex phenomena,find a simple rulefrom the nonlinear hydrological cycle simulation theory,a nonlinear water-carbon coupling model was developed based on the nonlinear system theory of the hydrological cycle and Jarvis stomatal conductance method.The experimental data at the Duke station of American-Flux and in the Chongling experimental watershed of the upstream of Baiyangdian were used to verify the model accuracy at the point and watershed scales.The results indicated that the nonlinear water-carbon coupling model can simulate the variations of evapotranspiration and soil moisture reasonably and accurately.The model was applied to estimate the effects of greenhouse gas discharge level on the hydrological cycle elements.When the concentration of carbon dioxide increases,the increase of runoff is 0.5%,increase of average soil moisture is 1.2%,while decrease of evaporation is 4.9%.Overall,the water-carbon coupling model achieves a simple solution to solve the complex problems.
