Maintaining and, where possible, improving the ecological status of our water resources are of particular importance for the future. So, one of the main drivers of landscape design must be to protect our waters. In this study, we carried out an evaluation of four hydrologic ecosystem services (HES) in the Zala River catchment area, the largest tributary of Lake Balaton (more than half of the lake’s surface inflow comes from the Zala River), Hungary. The lake has great ecological, economic and social importance to the country. We used the cell-based InVEST model to quantify the spatial distribution of flood control, erosion control and nutrient retention ecosystem services for phosphorus and nitrogen; then, we carried out an aggregated evaluation. Thereby, we localized the hot spots of service delivery and tested the effect of focused land use changes in critical areas of low performance on the examined four HES. Forests proved to have the best aggregated result, while croplands near the stream network performed poorly. The modelled change in land use resulted in significant improvement on nutrient filtration and moderate to minimal but improving change for the other HES in most cases. The applied method is suitable as a supporting tool at the watershed level for decision-makers and landscape designers with the aim of protecting water bodies.

维持并在可能的情况下改善水资源的生态状况对未来特别重要。因此，景观设计的主要驱动力之一必须是保护我们的水域。在这项研究中，我们对匈牙利巴拉顿湖最大支流（湖面流入量的一半以上来自扎拉河）扎拉河集水区的四种水文生态系统服务（HES）进行了评估。该湖对国家具有重要的生态、经济和社会意义。我们使用基于细胞的 InVEST 模型来量化磷和氮的防洪、侵蚀控制和养分保留生态系统服务的空间分布；然后，我们进行了汇总评估。从而，我们定位了服务提供的热点，并测试了在被检查的四个 HES 上表现不佳的关键区域的重点土地利用变化的影响。事实证明，森林的综合结果最好，而河流网络附近的农田表现不佳。在大多数情况下，土地利用的模拟变化导致养分过滤的显着改善和适度到最小但改善了其他 HES 的变化。所应用的方法适合作为流域层面的支持工具，为决策者和景观设计师提供保护水体的目的。在大多数情况下，土地利用的模拟变化导致养分过滤的显着改善和适度到最小但改善了其他 HES 的变化。所应用的方法适合作为流域层面的支持工具，为决策者和景观设计师提供保护水体的目的。在大多数情况下，土地利用的模拟变化导致养分过滤的显着改善和适度到最小但改善了其他 HES 的变化。所应用的方法适合作为流域层面的支持工具，为决策者和景观设计师提供保护水体的目的。
