Frequently, the plants used for the management of contaminated soil are those native to the area of action and provide a range of ecosystem services (ES). However, in many cases the sustainability of the afforestation planning and the provision of ES are not evaluated under scenarios of climate change (CC). In the present research work, we propose a fast‐track methodology for evaluating the potential distribution of forest species and provisioning of carbon sequestration under soil contaminated by trace elements. Furthermore, the effect of CC on the potential distribution was evaluated through the calibration of the Sierra model from MicroLEIS‐DSS. Seven tree species were selected due to their tolerance of soil contaminated by trace elements during the afforestation planning using the vegetation cover maps (1998–2013) of the Guadiamar Green Corridor. Additionally, compilation, standardization, and cluster process of soil database were applied following INSPIRE, EU‐HYDI, and JRC recommendations. Finally, the carbon sequestration rate of vegetation cover has been calculated according to IPCC methodology. The results show the loss of forest aptitude (Eucalyptus, P. pinea, P. alba, Quercus) under scenario of CC and decreasing of the ES provided. The proposed methodology could support the decision making to determine forest species suited for the regulation of contaminated soils and the provision of ES at spatiotemporal scales.

评估提供生态系统服务以支持针对土壤污染的植物修复措施。瓜迪亚马尔绿色走廊的案例研究(西班牙西南部)

通常,用于管理受污染土壤的植物是活动区域内的原生植物,并提供一系列生态系统服务(ES)。但是,在许多情况下,没有在气候变化情景下评估造林计划的可持续性和提供生态系统服务。在当前的研究工作中,我们提出了一种快速方法论,以评估森林物种的潜在分布以及在被微量元素污染的土壤下提供碳固存。此外,通过MicroLEIS-DSS中Sierra模型的校准评估了CC对电势分布的影响。选择了7种树种,是因为它们在使用Guadiamar Green Corridor的植被覆盖图(1998-2013年)进行造林规划时对微量元素污染的土壤具有耐受力。此外,根据INSPIRE,EU-HYDI和JRC建议,应用了土壤数据库的编译,标准化和聚类过程。最后,根据IPCC方法计算了植被覆盖的碳固存率。结果表明森林适应力的丧失(桉树PpineaP。在CC和减少ES的情况下提供albaQuercus)。所提出的方法可以支持决策的确定,以确定适合于受污染土壤调控的森林物种和时空尺度上的生态系统服务。
