生态系统服务的提供随自然和人为因素的变化而变化，但这一领域的研究主要是忽略社会生态系统内发生的时滞和反馈的分析。这方面的影响尚未研究，但核心是了解服务提供将如何改变，由于未来的土地利用/覆盖变化。城市地区的扩张速度比任何其他土地使用都要快，这使得城市成为研究此类遗留影响的理想研究系统。我们评估的程度，目前提供的一套8个生态系统服务，量化使用现场收集的数据，是由当前和历史（可追溯到150年）土地覆盖。五个服务（地上碳密度，娱乐用途，鸟类物种丰富度，鸟类密度，和一个度量的娱乐体验质量（与过去的连续性）更强烈地决定了过去的土地覆盖。时滞从20年（鸟类物种丰富度和密度）到100多年（地上碳密度）不等。因此，历史上的土地覆盖对目前的服务提供有很大的影响。如果忽视这种时间滞后，我们就有可能得出关于某些生态系统服务的分布和质量如何因土地利用/覆盖变化而改变的错误结论。虽然这一发现增加了预测未来情景的复杂性，但生态学家可能会发现，他们可以将生物多样性保护议程与文化遗产保护联系起来，某些行动方案可以在多种环境和文化产品中实现双赢。(C)2015作者爱思唯尔有限公司出版
Ecosystem service provision varies temporally in response to natural and human-induced factors, yet research in this field is dominated by analyses that ignore the time-lags and feedbacks that occur within socio-ecological systems. The implications of this have been unstudied, but are central to understanding how service delivery will alter due to future land-use/cover change. Urban areas are expanding faster than any other land-use, making cities ideal study systems for examining such legacy effects. We assess the extent to which present-day provision of a suite of eight ecosystem services, quantified using field-gathered data, is explained by current and historical (stretching back 150 years) landcover. Five services (above-ground carbon density, recreational use, bird species richness, bird density, and a metric of recreation experience quality (continuity with the past) were more strongly determined by past landcover. Time-lags ranged from 20 (bird species richness and density) to over 100 years (above-ground carbon density). Historical landcover, therefore, can have a strong influence on current service provision. By ignoring such time-lags, we risk drawing incorrect conclusions regarding how the distribution and quality of some ecosystem services may alter in response to land-use/cover change. Although such a finding adds to the complexity of predicting future scenarios, ecologists may find that they can link the biodiversity conservation agenda to the preservation of cultural heritage, and that certain courses of action provide win-win outcomes across multiple environmental and cultural goods.
