Abstract

Abstract: This study, conducted in experimental fields located in the Ili River Valley of Xinjiang, systematically investigatedthe effects of soybean-maize strip intercropping patterns on the structure and functional characteristics of arthropod communities. The findings aim to provide scientific insights for agricultural biodiversity cultivation and ecological pest management in soybean fields. Using a combination of five-point sampling and insect net methods, dynamic monitoring was conducted seven times across four planting patterns (monoculture, 2:2:2, 6:3, and 1:4:1). Diversity indices (Shannon-Wiener, Simpson dominance, Pielou evenness, and Margalef richness) were applied to analyze arthropod community diversity, stability, and ecological functions. A total of 2 classes, 13 orders, 40 families of arthropods were identified. Monoculture fields contained 2 classes, 13 orders, 29 families (36 species), while the 6:3, 2:2:2, and 1:4:1 intercropping patterns exhibited 32 families (42 species), 34 families (48 species), and 40 families (53 species), respectively. The three intercropping patterns significantly increased species richness, Margalefrichness, Pielou evenness, and Shannon-Wiener diversity, whereas monoculture showed higher Simpson dominance. Soybean-maize strip intercropping enhances ecosystem biodiversity, regulates pest-predator dynamics, and improves stability, thereby reducing crop damage. The 1:4:1 pattern, with optimal predatory subcommunity diversity and stability, is recommended for pest control in soybean-maize intercropping systems.

Key words: soybean-maize strip intercropping, arthropod community, community characteristics, stability
