摘要
【目的】探索、完善地下水动态敏感性分析方法。【方法】通过对地下水动态敏感性分析方法研究现状的分析,对地下水动态敏感性分析的概念进行了重新定义,并探索性地将正交试验与地下水动态建模相结合,用以进行地下水动态敏感性的分析。【结果】建立了基于改进正交试验法的地下水动态敏感性分析方法,将该方法用于宝鸡峡灌区,所得结果与现有其他方法所得结果相近,即均认为地表水灌溉量和蒸发量是影响灌区地下水动态的主要因素,并且该方法也在理论上克服了现有分析方法的一些局限性。【结论】基于改进正交试验法的地下水动态敏感性分析方法在实际中具有一定可行性,是对传统地下水动态敏感性分析方法的补充和完善。
【Objective】 The study was done to explore and perfect the methods on sensitivity analysis for the groundwater dynamics.【Method】 Based on analysis of the research status about the method on sensitivity analysis for the groundwater dynamics,we redefined the concept of sensitivity analysis for the groundwater dynamics and tentatively put forward an idea that the sensitivity of the groundwater dynamics can be analysed with the combination of the orthogonal experiment and the dynamic model of groundwater.【Result】 We established a new method on sensitivity analysis for the groundwater dynamics based on the improved orthogonal test method.It has been applied in the Baojixia irrigation district,and gives a good sensitivity outcome similar with other methods,that is,the amount of surface irrigation and the amount of evaporation capacity are the main factors affecting the groundwater dynamics in the Baojixia irrigation district.It also overcomes some limitations of the existing analysis methods.【Conclusion】 In practical application,the new method is feasible,and is a supplement for traditional study on groundwater dynamic sensitivity.
