Abstract

During the process of high-density urban development, the green spaces in residential areas become fragmented, which has a profound impact on the urban ecosystem. As an essential part of the ecosystem, the foraging behavior and diversity of pollinating insects are closely tied to green spaces. Studying the mechanism of fragmented green space in high-density urban residential areas on pollinating insects is of great significance for maintaining urban ecological balance and promoting biodiversity conservation. The fragmented green spaces exhibit features like miniaturized areas, scattered distribution, and simplified plant communities. Ecological functions are limited due to reduced habitat connectivity and a discontinuous spatial and temporal supply of resources. Pollinating insects have a demand for food resources and suitable habitat conditions, and plant traits and spatial perception influence their foraging behavior. Therefore, fragmented green space limits their resource accessibility, increases their behavioral adaptation and energy consumption, thus affecting their foraging behavior. It acts on pollinating insect diversity through the species screening effect, causing population isolation and barriers to gene exchange. In summary, an in-depth analysis of the mechanisms of the two can provide a scientific basis for optimizing the greening space of urban residential areas and protecting pollinating insects.
