Pollination mapping and modeling have opened new avenues for comprehending the intricate interactions between pollinators, their habitats, and the plants they pollinate. While the Lonsdorf model has been extensively employed in pollination mapping within previous studies, its conceptualization of bee movement in agricultural landscapes presents notable limitations. Consequently, a gap exists in exploring the effects of forest fragmentation on pollination once these constraints are addressed. In this study, our objective is to model pollination dynamics in fragmented forest landscapes using a modified version of the Lonsdorf model, which operates as a distance-based model. Initially, we generated several simulated agricultural landscapes, incorporating forested and agricultural habitats with varying forest proportions ranging from 10% to 50%, along with a range of fragmentation degrees from low to high. Subsequently, employing the modified Lonsdorf model, we evaluated the nesting suitability and consequent pollination supply capacity across these diverse scenarios. We found that as the degree of forest fragmentation increases, resulting in smaller and more isolated patches with less aggregation, the pollination services within landscapes tend to become enhanced. In conclusion, our research suggests that landscapes exhibiting fragmented forest patch patterns generally display greater nesting suitability due to increased floral resources in their vicinity. These findings highlight the importance of employing varied models for pollination mapping, as modifications to the Lonsdorf model yield distinct outcomes compared to studies using the original version.
授粉测绘与建模为理解传粉者、其栖息地以及它们所授粉的植物之间的复杂相互作用开辟了新途径。虽然朗斯多夫模型在以往研究的授粉测绘中得到了广泛应用，但其对农业景观中蜜蜂活动的概念化存在显著局限性。因此，一旦解决这些限制因素，在探索森林破碎化对授粉的影响方面就存在空白。在本研究中，我们的目标是使用朗斯多夫模型的修改版本对破碎森林景观中的授粉动态进行建模，该模型是一个基于距离的模型。首先，我们生成了几个模拟农业景观，纳入了森林和农业栖息地，森林比例从10%到50%不等，以及从低到高的一系列破碎化程度。随后，我们使用修改后的朗斯多夫模型，评估了这些不同情景下的筑巢适宜性以及随之而来的授粉供应能力。我们发现，随着森林破碎化程度的增加，导致斑块更小、更孤立且聚集性更低，景观中的授粉服务往往会得到增强。总之，我们的研究表明，由于其附近的花卉资源增加，呈现破碎森林斑块模式的景观通常表现出更高的筑巢适宜性。这些发现凸显了采用多种模型进行授粉测绘的重要性，因为与使用原始版本的研究相比，对朗斯多夫模型的修改产生了不同的结果。
