The perspective of ecosystem services bundle is virtually a spatial clustering on landscape to mapping the relationship between ecosystem services and support the spatial strategy of landscape management. However, the efficiency of various clustering algorithms for geographically different regions are still in obscurity. In this study, we provided landscape functional zoning as a planning tool based on the ecosystem services bundles formed by carbon sequestration, soil retention and water yield. Then we used four landscape pattern indices to evaluate the performance of six clustering algorithms on landscape functional zoning. The case counties include Lankao, Jinggangshan and Luquan in China. The results showed the Natural Breaks (Jenks) scheme should be the most reasonable zone because of its high aggregated distribution and low diversity. This scheme was adjusted using some other schemes and has been employed as the final 7 kinds of zoning types. There were 5 types appeared in Lankao and Jinggangshan, and 6 types appeared in Luquan. We discussed that landscape functional zone can be a nexus connecting landscape planning and social policy. Rural reconstructing process on landscape was depicted, and landscape functional zone was proposed a practical planning tool bridged human wellbeing. The task of landscape functional zoning with the management indications may provide interdisciplinary support to decision-makers and natural resource users on landscape management.
生态系统服务束的观点实际上是对景观进行空间聚类，以映射生态系统服务与景观管理空间策略之间的关系。然而，各种聚类算法在地理上不同区域的效率仍然不清楚。在本研究中，我们提供了基于碳封存、土壤保持和产水量形成的生态系统服务束的景观功能分区，作为一种规划工具。然后，我们使用了四个景观格局指数来评估六种聚类算法在景观功能分区上的性能。案例县包括中国兰考、井冈山和鹿泉。结果表明，自然断点（Jenks）方案应该是最合理的分区，因为它具有较高的聚集分布和较低的多样性。该方案经过其他方案的调整，最终被划分为 7 种分区类型。在兰考和井冈山出现了 5 种类型，在鹿泉出现了 6 种类型。我们讨论了景观功能区可以作为连接景观规划和社会政策的纽带。描述了景观上的农村重构过程，提出了景观功能区作为连接人类福祉的实用规划工具。具有管理指示的景观功能分区的任务可以为决策者和自然资源使用者提供景观管理的跨学科支持。
