农业集约化导致地面节肢动物和相关生态系统服务严重减少。在农业景观中保护和重建半自然生境是被广泛接受的应对这些下降的措施。然而，这些措施的有效性在目标类群及其功能特征之间存在差异，同时也受到当地管理的影响。在这里，我们研究了不同功能组的步甲和蜘蛛在苹果园的物种丰富度和丰富度的影响景观复杂性（%半自然栖息地）和当地的管理强度（割草和土壤总氮（NO3）含量）。非肉食性步甲和步甲的总体丰度和物种丰富度均受到割草的负面影响，而肉食性步甲和步甲的总体丰度则受到割草和景观复杂性的交互作用的影响，在半自然栖息地稀缺的情况下，割草表现出积极的响应，但在半自然栖息地比例较高的景观中表现出消极的响应。地猎蜘蛛和蜘蛛总体丰度与%半自然生境总体呈正相关，而结网蜘蛛丰度和地猎蜘蛛物种丰富度与低或中等丰度半自然生境景观呈正相关，但与半自然生境更丰富的景观呈负相关。非肉食性步甲的多样性受益于低氮的应用，而肉食性步甲丰度受益于割草强度，特别是在简单和结构均匀的农业景观。建网和地面狩猎蜘蛛积极响应低氮应用和中间景观复杂性。总体而言，较低的当地管理强度促进了步甲的生长，而蜘蛛则因景观复杂性的增加而受到青睐。我们的结论是，分类群和功能群的具体，多尺度的保护策略，因此需要保护无脊椎动物捕食者在苹果园。
Agricultural intensification has caused severe declines in ground-dwelling arthropods and associated ecosystem services. The conservation and re-establishment of semi-natural habitats in agricultural landscapes represent widely accepted measures to counter these declines. The effectiveness of these measures nonetheless varies between target taxa and their functional traits, while also being affected by local management. Here, we studied how species richness and abundance of different functional groups of carabid beetles and spiders in apple orchards were affected by landscape complexity (% semi-natural habitat) and local management intensity (mowing and soil total nitrogen (STN) content). Both abundance and species richness of non-carnivorous carabids and carabids overall were negatively affected by STN, while the abundance of carnivorous carabids and carabids overall was affected by interactive effects of mowing and landscape complexity, showing a positive response to mowing where semi-natural habitats are scarce, but negative responses in landscapes with a higher proportion of semi-natural habitats. The abundance of ground-hunting spiders and spiders overall was generally positively related to % semi-natural habitats, while the abundance of web-building spiders and the species richness of ground-hunting spiders showed a positive correlation with STN at landscapes with a low or medium abundance of semi-natural habitats, but a negative correlation where semi-natural habitats were more abundant. Non-carnivorous carabid diversity benefitted from low nitrogen application, while carnivorous carabid abundance benefitted from mowing intensity especially in simple and structurally homogenous agricultural landscapes. Both web-building and ground-hunting spiders positively responded to low nitrogen applications and intermediate landscape complexity. Overall, a low local management intensity promoted carabid beetles, while spiders were favored by increasing landscape complexity. We conclude that taxon- and functional group-specific, multi-scale conservation strategies are therefore required to conserve invertebrate predators in apple orchards.
