摘要

田边等线性景观要素是农业环境气候措施(AECMs)支持采用的农业措施。农业环境气候措施旨在改善农场及周边地区的生态条件。农业环境气候措施在提高多种生态系统服务(ESs)供应方面的有效性仍存在争议,而有关农业环境气候措施在不同实践下产生的生态系统服务束的知识仍然缺乏。我们旨在评估促进线性景观要素实施的 AECM 在提供高水平的多重生态系统服务方面的潜力,并分析不同地理环境下景观层面的生态系统服务束。我们评估了线性景观要素(木本植物、草本植物、花卉和混合植物)对六种环境服务(食物和饲料供应、授粉、害虫控制、气候调节、美学和生境维护)的潜在影响,并结合了情景模拟和空间显式建模方法。我们的研究结果表明,线性景观要素对所有调节和文化 ES 都有积极影响。线性景观要素越丰富,整体生态系统服务供应量就越高。然而,线性景观要素对多种生态系统服务的影响取决于线性要素的类型及其实施的地理环境。当基线环境中的生态系统供应量已经很高时,线性元素的实施所引起的变化要比基线环境中一种或几种生态系统的初始供应量较低时低得多。我们的分析使人们深入了解了针对多个环境目标的 AECM 的效率。我们的方法是为事先综合分析 AECM 的一般框架迈出的第一步,该框架可用于设计农业环境政策。从更实际的角度来看,我们的研究结果可以作为为农业生态补偿机制提供额外付款的基础。我们的研究还证实了欧盟生物多样性战略的相关性,该战略承诺确保至少 10% 的农业面积具有高生物多样性景观特征(如线性景观要素),以及改革后的共同农业政策中针对非生产要素和生物多样性的强化条件和生态计划的相关性。

Effects of linear landscape elements on multiple ecosystem services in contrasting agricultural landscapes

Linear landscape elements, such as field margins, are agricultural practices whose adoption is supported by agri-environmental climate measures (AECMs). AECMs are meant to improve ecological conditions on farms and surrounding areas. The effectiveness of AECMs to enhance the supply of multiple ecosystem services (ESs) is still debated and knowledge on the resulting ESs bundles under different practices stemming from AECMs is still lacking. We aimed at assessing the potential of AECMs that promote the implementation of linear landscape elements to provide high levels of multiple ESs and at analyzing bundles at landscape level in different geographical contexts. We assessed the potential effects of linear landscape elements (woody, grassy, flower and a mix) on six ESs (food and feed provision, pollination, pest control, climate regulation, aesthetics, and habitat maintenance), combining scenarios and spatially explicit modelling approaches. Our results showed the positive effects of linear landscape elements on all regulating and cultural ESs. The more abundant the linear elements, the higher the overall ESs supply. However, the effect of linear landscape elements on multiple ESs depended on the types of linear elements and the geographical context of their implementation. When the supply of the ES was already high in the baseline situation, the changes induced by the implementation of the linear elements were much lower than when the baseline situation showed a lower initial supply of one or several of the ESs. Our analyses give insights on the efficiency of AECMs on multiple environmental targets. Our approach is a first step towards a general framework for an ex-ante integrated analysis of AECMs that can be used to design agri-environmental policies. From a more practical perspective, our results can form a basis for additional payments for AECMs. Our study also confirms the relevance of the EU biodiversity strategy that commits to ensure at least 10% of agricultural area as high-biodiversity landscape features such as linear landscape elements, and the relevance of the enhanced conditionality and eco-schemes in the reformed Common agricultural Policy targeting non-productive elements and biodiversity.

期刊介绍: Ecosystem Services is an international, interdisciplinary journal that is associated with the Ecosystem Services Partnership (ESP). The journal is dedicated to exploring the science, policy, and practice related to ecosystem services, which are the various ways in which ecosystems contribute to human well-being, both directly and indirectly. Ecosystem Services contributes to the broader goal of ensuring that the benefits of ecosystems are recognized, valued, and sustainably managed for the well-being of current and future generations. The journal serves as a platform for scholars, practitioners, policymakers, and other stakeholders to share their findings and insights, fostering collaboration and innovation in the field of ecosystem services.
