城市周边农田提供了多样化的生态服务。然而，它正经历着来自城市扩张的越来越大的压力。虽然与耕作相关的土地利用对节肢动物群落的影响越来越受到关注，但这项研究的大部分是通过比较传统种植制度和有机种植制度进行的。本研究确定了城市蔓延的影响和非种植生境在确定城市周边农田景观中节肢动物多样性方面的作用。利用30个样地的多尺度节肢动物数据，采用线性混合模型分析了距市区距离(0-13 公里、13-25 公里和>；25 公里，分别为I、II、III区)对节肢动物的影响。结果表明，城市蔓延、农田景观干扰和非耕作生境干扰对节肢动物有负面影响，后者要求节肢动物每年通过扩散从周围景观中重建。而节肢动物物种丰富度变化不明显，节肢动物丰富度在II区最低。一般来说，非种植生境的斑块密度(PD)、Shannon多样性指数(SHDI)和聚集指数(AI)是节肢动物种群变化的主要驱动因素。这项研究有助于确定城市蔓延对节肢动物多样性的影响，并记录城市近郊农田景观的多重功能。
Peri-urban farmland provides a diversity of ecological services. However, it is experiencing increasing pressures from urban sprawl. While the effects of land use associated with farming on arthropod assemblages has received increasing attention, most of this research has been conducted by comparing conventional and organic cropping systems. The present study identifies the effects of urban sprawl and the role of non-cropped habitat in defining arthropod diversity in peri-urban farmed landscapes. Multi-scale arthropod data from 30 sampling plots were used with linear-mixed models to elucidate the effects of distance from urban areas (0–13 km; 13–25 km and >25 km, zones I, II, and III, respectively) on arthropods. Results showed that urban sprawl, disturbed farm landscapes, and disturbance in non-cropped habitats had negative effects on arthropods, the latter requiring arthropods to re-establish annually from surrounding landscapes via dispersal. While arthropod species richness showed no obvious changes, arthropod abundance was lowest in zone II. Generally, patch density (PD), Shannon diversity index (SHDI), and aggregate index (AI) of non-cropped habitat were major drivers of changes in arthropod populations. This study contributes to identifying the effects of urban sprawl on arthropod diversity and documenting the multiple functions of farm landscapes in peri-urban regions.
