Multi-Scale Effects of Landscape Stucture on Epigaeic Arthropods Diversity in Arable Land System: A Case in Changtu County of Northern China

Understanding the multi-scale effects of arable land landscape on epigaeic arthropod diversity is essential for biodiversity conservation and agroecosystem services. Our study explored overall effect elements at three scales landscape, habitat, field. We selected 11 areas to sample using trap method, construct models data. The results showed that: (1) On scale, 1500 m was optimal radius. Shannon’s index interspersion juxtaposition can explain arthropods level 76.7%. (2) habitat scale (the radius less than 100 m), types significantly affected species number, Pielou evenness index, individual number (p < 0.05). distribution had an obvious margin effect. (3) field we also revealed Shannon herb vegetation structure change community 69.1%. believe that appropriate best lever protect agricultural biodiversity. research promote integrated regional sustainable development systems.
