In the context of the unprecedented loss of biodiversity, effective conservation assessment approaches are critical for preserving both species diversity and ecosystem processes. Since ecosystem processes also provide services that benefit society directly, for example, storm attenuation and water filtration, integrating delivery of ecosystem services into conservation assessments would increase social acceptance of conservation. To date, the degree of spatial congruence between ecosystem services and species diversity has only begun to be explored. This has been done mainly through the identification of hot spots of maximal production of ES and species, which generally do not overlap spatially. Integrating ES into the process of systematic site selection should improve not only the protection of species diversity but also functional diversity. Indeed, functional diversity, as defined by the value, range and relative abundance of biological attributes (traits) in a community, is believed to be more strongly associated with ecosystem processes than species diversity per se. It may therefore become an important component of conservation assessments when integrating ecosystem services.

在生物多样性空前丧失的背景下，有效的保护评估方法对于保护物种多样性和生态系统过程至关重要。由于生态系统过程还提供直接造福社会的服务，例如减弱风暴和过滤水，因此将生态系统服务纳入保护评估将增加社会对保护的接受程度。迄今为止，生态系统服务与物种多样性之间的空间一致性程度的探索才刚刚开始。这主要是通过识别ES和物种最大生产的热点来实现的，这些热点在空间上通常不重叠。将ES纳入系统选址过程，不仅可以提高物种多样性的保护，还可以提高功能多样性的保护。事实上，功能多样性被定义为群落中生物属性（特征）的价值、范围和相对丰度，被认为与生态系统过程的关系比物种多样性本身更为密切。因此，在综合生态系统服务时，它可能成为保护评估的一个重要组成部分。
