Cities are increasingly developing renewable energy within urban areas, yet the implications for ecosystems have not been explored. This study brings together climate change mitigation policies and ecosystem conservation in urban areas by investigating how ground-mounted solar arrays in parking lots affect arthropod abundance and biodiversity. We assess which arthropods are present under these solar canopies and investigate how integration of vegetation under the solar arrays affects arthropod abundance, abundance of different functional groups, and family richness. We sampled arthropods, collected data on habitat characteristics, and evaluated landscape cover within 2 km of eight study sites around San Jose and Santa Cruz, California. We found substantial abundance and diversity of arthropods underneath ground-mounted solar arrays in urban area parking lots, and that arrays integrated with vegetation have significantly greater arthropod abundance and more detritivores, parasitoids, and family richness. The results demonstrate that ground-mounted solar arrays in parking lots, especially when integrated with vegetation, can be a win-win for climate mitigation, arthropod richness, and ecosystem functioning.

城市在城市区域内越来越多地开发可再生能源，但尚未探索对生态系统的影响。这项研究通过研究停车场的地面太阳能电池阵列如何影响节肢动物的丰度和生物多样性，将城市地区的减缓气候变化政策和生态系统保护结合在一起。我们评估了在这些太阳冠层下存在哪些节肢动物，并研究了太阳能电池阵列下的植被整合如何影响节肢动物的丰度，不同功能群体的丰度以及家庭的富裕程度。我们对节肢动物进行了采样，收集了栖息地特征的数据，并评估了加利福尼亚州圣何塞和圣克鲁斯附近八个研究地点2公里内的景观覆盖度。我们发现市区停车场地面安装的太阳能电池阵列下的节肢动物数量众多且种类繁多，并且与植被整合的阵列中节肢动物的数量显着增加，并且有更多的有害生物，寄生物和家庭财富。结果表明，在停车场中安装在地面上的太阳能电池阵列，尤其是与植被整合在一起的太阳能阵列，可以在缓解气候变化，节肢动物丰富度和生态系统功能方面取得双赢。
