【摘要】 [目的]掌握皖南山区宁国市昆虫多样性及特征分布，并提出一系列昆虫多样性保护措施，开展了宁国市昆虫多样性调查工作。[方法]采用样线法、样方法对当地的昆虫进行采集调查，将采集到的昆虫数据进行多样性指数分析。[结果]共记录到昆虫1 098种(其中国家重点保护物种4种，安徽省重点保护物种2种),隶属于19目181科825属。其中，昆虫物种数量最多的是鳞翅目，昆虫类群科级数量最多的是鞘翅目，昆虫类群属级数量最多的是鳞翅目；在不同时空分布下，9月的昆虫种类最多，灌丛生境是昆虫物种多样性最丰富的地区。Shannon-Wiener丰富度指数最高的网格是63003310,Pielou均匀度指数最高的网格为63203340。影响宁国市昆虫多样性的因子主要包括生境破坏、农药污染、极端天气。[结论]建议宁国市合理使用农药，保护有益昆虫，合理利用昆虫资源，加强自然保护区建设，持续开展昆虫多样性基础研究。更多还原

【Abstract】 [Objective] To figure out the diversity and characteristic distribution of insects in Ningguo City which is located in the mountain area of Southern Anhui, and propose a series of conservation measures. [Method]The line transect and quadrat methods were used to collect and investigate local insects, and the collected insect data was analyzed through diversity index analysis.[Result]1 098 insect species were recorded(including 4 nationally key protected species and 2 Anhui provincial key protected species), belonging to 19 orders, 181 families, and 825 genera. Lepidoptera is the most species-rich order, Coleoptera has the highest number of families, and Lepidoptera also contains the highest number of genera. In terms of spatiotemporal distribution, the highest insect diversity was observed in September, with shrubland habitats exhibiting the richest insect diversity. The 63003310 grid shows the highest Shannon-Wiener richness index, while the 63203340 grid represents the highest Pielou evenness index. Key factors affecting insect diversity in Ningguo City include habitat destruction, pesticide pollution, and extreme weather. [Conclusion]Recommendations include rational pesticide use, protection of beneficial insects, sustainable utilization of insect resources, enhanced construction of natural reserves, and continuous foundational research on insect diversity.更多还原
