Butterflies are crucial bioindicators of urban environmental changes. Utilizing urban green spaces to create ecological corridors and habitats is essential for maintaining biodiversity. Therefore, understanding the factors that influence landscape patterns in urban green spaces and their impact on butterfly diversity is crucial. This study investigated how landscape patterns in urban green spaces affect butterfly diversity through a year-long survey across 24 urban parks in Fuzhou. The main findings were as follows: (1) A total of 7786 butterflies from 59 species were recorded, with the highest species diversity and richness observed in Fushan Country Park. Seasonal abundance peaked in summer, while richness was highest in autumn. Species composition varied significantly across park types. (2) Monophagous butterfly diversity was positively correlated with woodland proportion and negatively to waterbody largest patch index. Polyphagous and oligophagous butterfly diversity showed positive correlations with woodland aggregation index and grassland proportion within 500 m buffers, but negative with construction land proportion. Factors such as the waterbody proportion and landscape division index influenced butterfly diversity in different activity spaces. (3) Butterfly communities with different feeding types and vertical activity space ranges responded differently to landscape pattern indices. Seasonal variations indicated that polyphagous butterflies and those occupying the middle activity space exhibited similar responses to environmental factors.
蝴蝶是城市环境变化的关键生物指示物种。利用城市绿地创建生态廊道和栖息地对于维护生物多样性至关重要。因此，了解影响城市绿地景观格局的因素及其对蝴蝶多样性的影响至关重要。本研究通过对福州24个城市公园进行为期一年的调查，探究了城市绿地景观格局如何影响蝴蝶多样性。主要研究结果如下：（1）共记录到7786只蝴蝶，分属59个物种，其中福山郊野公园的物种多样性和丰富度最高。季节性丰度在夏季达到峰值，而丰富度在秋季最高。不同公园类型的物种组成差异显著。（2）单食性蝴蝶多样性与林地比例呈正相关，与水体最大斑块指数呈负相关。多食性和寡食性蝴蝶多样性与500米缓冲区内的林地聚集指数和草地比例呈正相关，但与建设用地比例呈负相关。水体比例和景观分割指数等因素在不同活动空间影响蝴蝶多样性。（3）具有不同取食类型和垂直活动空间范围的蝴蝶群落对景观格局指数的响应不同。季节性变化表明，多食性蝴蝶和占据中间活动空间的蝴蝶对环境因素表现出相似的响应。
