以城市化形式出现的土地使用变化是影响森林提供生态系统服务的直接驱动因素。为了更好地理解这一驱动因素，我们模拟了城市化对美国佛罗里达两个不同流域三个调节和提供生态系统服务的影响。该研究综合了现有的地理空间和地块一级的森林清查数据，以评估57年期间碳储存、木材体积和水量的未来变化。利用土地覆被数据和人口分布模型制定了2003-2060年城市化和土地利用变化情景。然后使用综合评估和生态系统服务权衡模型来量化生态系统服务的变化。在城市化的2060年情景中，下苏瓦尼农村和彭萨科拉湾城市流域的碳储量分别减少了16%和26%。木材量减少了11%，在下苏瓦尼和21%，在彭萨科拉湾流域。然而，两个流域的产水量增加了4%。确定并绘制了最易受城市化影响的具体分流域，并讨论了生态系统服务的相互作用或权衡和协同增效。研究结果揭示了城市化如何驱动生态系统服务及其权衡的时空动态。本研究为决策者和规划者提供了一种更好地开发综合建模方案以及设计土地利用变化和生态系统服务评估的绘图和监测协议的方法。(C)2016爱思唯尔有限公司版权所有
Land use change in the form of urbanization is a direct driver affecting the provision of ecosystem services from forests. To better understand this driver, we modeled the effects of urbanization on three regulating and provisioning ecosystem services in two disparate watersheds in Florida, USA. The study integrated available geospatial and plot-level forest inventory data to assess future changes in carbon storage, timber volume and water yield during a period of 57 years. A 2003-2060 urbanization and land use change scenario was developed using land cover data and a population distribution model. The Integrated Valuation and Ecosystem Services Tradeoffs model was then used to quantify changes in ecosystem services. Carbon storage was reduced by 16% and 26% in the urbanized 2060 scenario in both the rural Lower Suwannee and urban Pensacola Bay watersheds, respectively. Timber volume was reduced by 11% in the Lower Suwannee and 21% in the Pensacola Bay watershed. Water yield, however, increased in both watersheds by 4%. Specific sub-watersheds that were most susceptible to urbanization were identified and mapped and ecosystem service interactions, or trade-offs and synergies, are discussed. Findings reveal how urbanization drives the spatio-temporal dynamics of ecosystem services and their trade-offs. This study provides policy makers and planners an approach to better develop integrated modeling scenarios as well as designing mapping and monitoring protocols for land use change and ecosystem service assessments.
