Abstract

The water conservation service function, which is one of the most important ecological service function in the regional system, directly reflects the regulation role of a region in precipitation, the redistribution function of precipitation, and the ecohydrological value. With the development of the comprehensive evaluation method and the deepening of research on water conservation service function, relevant evaluation calculation process has changed significantly. Nowadays, in the assessment of the water conservation service function, it is necessary not only to calculate and evaluate relevant indicators, but also to localize specific parameters in the model and analyze the effectiveness of the overall model for specific study areas. However, the current literature review lacks systematic summaries of model evaluation methods. Meanwhile, the review is also insufficient on model validity verification and significance analysis methods, the result verification and applicability analysis methods such as parameter localization in water conservation studies. We reviewed the research advance on typical ecosystem water conservation ser-vice assessment methods with a specific focus on the model assessment methods that have developed rapidly in recent years. At the same time, we summarized methods commonly used for parameter localization, as well as validity testing and sensitivity analysis of simulation results, and discussed existing problems and future directions in this field.

生态系统水源涵养服务功能可以直观地反映区域对降水的调节作用和对降水的重新分配功能及生态水文价值,是区域系统中至关重要的生态服务功能之一。随着模型综合评估方法的发展和水源涵养服务功能研究的不断深入,相关评估计算流程也发生了明显变化。如今,在进行水源涵养服务功能评估时,不仅需要计算和评估相关的指标,还需要对特定参数进行本地化和对模型进行有效性分析,以更好地适用于具体的研究区域。然而,当前综述文献普遍缺乏对模型评估方法的系统性汇总,同时,缺少关于水源涵养研究的模型有效性验证和显著性分析方法、参数本地化等结果验证及适用性分析方法的综述性文献。本文梳理了典型的生态系统水源涵养服务功能评估方法的研究进展,并重点介绍近年来发展迅速的模型评估法。同时,汇总了目前该领域研究中常见的参数本地化方法、模拟结果的有效性检验方法和敏感性分析方法,并探讨了当前研究存在的问题和未来发展方向。.
