棕地旧址重建提供了创造城市绿色空间的机会，提供广泛的生态系统服务。因此，重要的是要了解利益相关者需要哪些生态系统服务，以及这种需求是否存在权衡或协同效应。我们对棕地的生态系统服务需求进行了定量调查，其中包括所有主要的利益相关者群体。结果显示，对与房地产开发相关的服务（例如地面强度和低洪水风险）和所有其他与植被相关的服务的需求之间存在很强的权衡关系。在对更“自然”的植被站点（例如具有生物多样性保护作用）的服务需求与与美学和娱乐相关的服务需求之间存在次要的，但较弱的权衡。具有强烈生物多样性保护偏好的利益相关者在生态系统服务需求上形成了一个明显的群体。虽然“发展”与“绿色空间”之间的权衡可能是不可避免的，但对其他服务的需求普遍缺乏强有力的权衡，这表明，只要这些在生物物理上是可能的，大多数利益相关者都希望从以前的棕地地块创造多功能的绿色空间。
Brownfield site redevelopment presents an opportunity to create urban green spaces that provide a wide range of ecosystem services. It is important, therefore, to understand which ecosystem services are demanded by stakeholders and whether there are trade-offs or synergies in this demand. We performed a quantitative survey of ecosystem service demand from brownfield sites that included all major stakeholder groups. Results showed that there was a strong trade-off between demand for services related to property development (e.g. ground strength and low flood risk) and all other services, which were linked to vegetated sites. There was a secondary, but weak, trade-off between demand for services of more ‘natural’ vegetated sites (e.g. with a biodiversity protection role) and those linked to aesthetics and recreation. Stakeholders with a strong preference for biodiversity protection formed a distinct group in their ecosystem service demands. While a ‘development’ vs ‘green space’ trade-off may be unavoidable, the general lack of strong trade-offs in demand for other services indicated that the creation of multifunctional greenspaces from former brownfield sites would be desirable to most stakeholders, as long as these are biophysically possible.
