摘要：

农业用地的变化会影响生态系统服务及其相互作用。然而，人们对不同地形梯度下农业用地转型对生态系统服务相互作用的不同影响仍知之甚少。这限制了农业系统的综合管理。我们的目标是分析不同地形梯度上主要农业用地类型的转型趋势，并探究这些转型对生态系统服务相互作用的不同影响。以杭州为研究区域，重点分析了四种主要的农业用地类型（耕地、果园、茶园和废弃地）。利用GTWR模型研究了它们的转型对生态系统服务权衡/协同作用的影响的时空非平稳性。结果表明，在2010-2020年期间，平原地区的农用地利用格局变得更加多样化和分散化，而丘陵和山地地区的农用地利用格局则转向更加单一和连片。在2010-2015年和2015-2020年期间，农业用地转型的主要输出类型是耕地。平原地区的主要输入类型从耕地转变为果园，而丘陵和山地地区则为果园和茶园。生境质量与其他生态系统服务之间较强的协同作用主要在平原地区。随着时间的推移，碳固存和土壤保持之间较强的协同作用主要从山地地区转移到平原地区。不同地形梯度上各种废弃类型通过削弱各类生态系统服务的供给能力，进而促进了它们之间的协同效应。在丘陵和山地地区，生态系统服务之间的权衡可通过将耕地转化为果园和茶园来缓解。这些发现强调了在不同地形梯度的生态系统管理中采取差异化、动态化和系统化的农业空间发展措施的重要性。

Abstract:

Changes in agricultural land use affect ecosystem services and their interactions.  However, the differential influences of agricultural land use transitions under different topographical gradients on ecosystem service interactions remain poorly understood, which limits the integrated management of agricultural systems.  The objectives of this study were to analyze the transitional trends of major agricultural land types across distinct topographical gradients and to probe the differential impacts of these transitions on ecosystem service interactions.  Using Hangzhou of China as the study area, the analysis focused on four major agricultural land use types (arable land, orchard, tea garden, and abandoned land).  The GTWR model was applied to investigate spatiotemporal non-stationarity in the impacts of their transitions on the ecosystem service trade-offs and synergies.  The results showed that during 2010–2020, the agricultural land use pattern in plain areas became more diversified and fragmented, while it shifted towards greater homogeneity and contiguity in hilly and mountainous areas.  Between 2010–2015 and 2015–2020, the dominant output type of agricultural land use transition was arable land.  The dominant input type in plain areas shifted from arable land to orchard, whereas in hilly and mountainous areas, it was orchard and tea garden.  The higher synergy between habitat quality and other ecosystem services primarily occurred in plain areas.  Over time, the higher synergy between carbon sequestration and soil retention predominantly shifted from mountainous areas to plain areas.  A variety of abandoned types across different topographical gradients fostered synergies by reducing the supply capacity of various ecosystem services.  Trade-offs between ecosystem services in hilly and mountainous areas could be alleviated by converting arable land into orchard and tea garden.  These findings highlight the importance of adopting differentiated, dynamic, and systematic measures for agricultural spatial development in implementing ecosystem management across different topographical gradients.
