中文摘要: 为正确评价与合理利用若尔盖湿地水资源,对湿地SPAC系统的水分运移规律进行研究。在分别研究土壤-植物-大气各子系统及其界面的基础上,输入模型计算所需参数数据,建立湿地SPAC耦合模型。采用实测的参数验证模型,并取一定幅度变动主要参数来运算,判别模型对不同参数的敏感性。结果表明,耦合模型可以较好地描述湿地的生态-水文过程,并得到湿地植物生长的“理想”的地下水埋深(60~100cm)和“适宜”的地下水埋深(0~60cm和100~250cm)。
Abstract:This paper studied the water flow of SPAC system in Zoige wetland, so as to evaluate accurately and utilize suitably water resource of wetland. Based on the distinctive studies on the sub systems of soil plant atmosphere systems and their interfaces, a new approach of simulation is carried out using coupled model by inputting data needed. The model is tested by using the measured parameters, and the model is run under the conditions of changing the values of the main parameters within certain range to analyze the sensitivity of the parameters. This model can describe the eco hydrology process of Zoige wetland. The result shows that for Zoige wetland plant, the “ideal” ground water level is 60~100 cm, and the “feasible” ground water level is 0~60 cm and 100~250 cm.
