Since there are various stakeholders related to water in Blue-Green Infrastructure that perform various ecological functions in a given city, there is a need for a plan to manage their interests and conflicts. Previous studies have verified the spatial preferences of many local residents using techniques, such as the public participation geographic information system, but have failed to show how stakeholders vary in regard to their dependence on water and their different spatial preferences. Therefore, this study intended to discuss the direction of collaborative planning by analyzing the Blue-Green Infrastructure of Siheung Hojobul wetland using spatial Q methodology, finding various stakeholders, and identifying the areas they prefer. The analysis results showed that local residents and environmental NGOs want to conserve middle and upper streams, but ecotourism guides and officials want to develop them for ecotourism, demonstrating a great difference in perspectives. However, they all agreed to develop a lower stream for ecotourism. Although this study has limitations as a single case study, the spatial Q methodology used in this study is significant in demonstrating that the use of the Blue-Green Infrastructure planning method for resident participation can reduce conflicts and encourage cooperation among competing parties.

由于蓝绿基础设施中有各种与水相关的利益相关者，在特定城市中执行各种生态功能，因此需要制定计划来管理他们的利益和冲突。先前的研究已经使用公众参与地理信息系统等技术验证了许多当地居民的空间偏好，但未能展示利益相关者在对水的依赖和不同空间偏好方面的差异。因此，本研究旨在通过使用空间 Q 方法分析始兴 Hojobul 湿地的蓝绿基础设施，寻找各种利益相关者，并确定他们喜欢的区域来讨论协作规划的方向。分析结果显示，当地居民和环保NGO希望保护中上游，而生态旅游指导和官员希望开发它们用于生态旅游，显示出巨大的视角差异。然而，他们都同意开发生态旅游的下游。尽管本研究作为单一案例研究存在局限性，但本研究中使用的空间 Q 方法对于证明使用蓝绿基础设施规划方法进行居民参与可以减少冲突并鼓励竞争方之间的合作具有重要意义。
