Numerous studies have emphasised the ecological importance of linear and insular uncropped habitats, including forest shelterbelts, patches, and grassy margins. Usually, their biodiversity-enhancing effects are mentioned, mainly based on research in bird and above-ground arthropod communities, while the diversity of herbaceous vegetation and soil mesofauna is barely mentioned. Our research investigated the impact of six different habitats (cultivated areas, grassy field margins, shelterbelts and their grassy edges, forest and grassland patches) on soil-related diversity in an agroforestry landscape. We concentrated on the diversity and species composition of herbaceous and soil microarthropod communities, which sensitively indicate the effect of the structure and management of the different ecotones on ecological conditions. Our research found that both shelterbelts and grassy margins provide better habitats for major microarthropod groups than cultivated fields. Concerning shelterbelts of different tree species, QBS-ar showed better soil biological conditions in the belt dominated by the native field maple when compared to the non-native black locust. Collembola was more abundant inside the shelterbelts than in their edges, while diversity showed an opposite pattern. The soil fauna and coenology results reflect the importance of habitat variability in agroforestry landscape by increasing soil-related invertebrate and herbaceous communities' diversity.

农林业景观中的土壤中型动物和草本植被模式

许多研究都强调了线性和孤立的未耕种栖息地的生态重要性,包括森林防护林带、斑块和草地边缘。通常,它们的生物多样性增强作用被提及,主要基于对鸟类和地上节肢动物群落的研究,而很少提及草本植被和土壤中型动物的多样性。我们的研究调查了六种不同栖息地(耕地、草地边缘、防护林及其草地边缘、森林和草地斑块)对农林业景观中土壤相关多样性的影响。我们专注于草本和土壤微型节肢动物群落的多样性和物种组成,这敏感地表明了不同交错带的结构和管理对生态条件的影响。我们的研究发现,与耕地相比,防护林带和草地边缘都为主要的微型节肢动物群体提供了更好的栖息地。就不同树种的防护林带而言,QBS-ar与非本地刺槐相比,在以本地枫树为主的林带中表现出更好的土壤生物条件。跳虫在防护林内比在其边缘更丰富,而多样性则显示出相反的模式。土壤动物群和群落学结果通过增加与土壤相关的无脊椎动物和草本群落的多样性反映了生境变异在农林业景观中的重要性。与非本土刺槐相比,QBS-ar在以本土枫树为主的地带表现出更好的土壤生物条件。跳虫在防护林内比在其边缘更丰富,而多样性则显示出相反的模式。土壤动物群和群落学结果通过增加与土壤相关的无脊椎动物和草本群落的多样性反映了生境变异在农林业景观中的重要性。与非本土刺槐相比,QBS-ar在以本土枫树为主的地带表现出更好的土壤生物条件。跳虫在防护林内比在其边缘更丰富,而多样性则显示出相反的模式。土壤动物群和群落学结果通过增加与土壤相关的无脊椎动物和草本群落的多样性反映了生境变异在农林业景观中的重要性。
