摘要
为了解燕山地区访花昆虫的群落结构及与其生境类型、干扰程度、海拔之间的关系,本文采用样线法和灯诱法于2019年、2020年每年的7-8月对该地区湿地、森林、灌丛、草地、农田5种生境,不同海拔梯度(0-1,200 m)的访花昆虫进行了采集。共采集访花昆虫1,306头,隶属7目44科153种,其中鳞翅目昆虫物种数最多,半翅目昆虫个体数最多。灌丛生境的访花昆虫多样性最高。在中低海拔200-400 m段,Shannon-Wiener多样性指数、Margalef丰富度指数和Simpson优势度指数均最高。双变量回归结果表明,Shannon-Wiener多样性指数和Margalef丰富度指数分别与最暖季降水量和年降水量显著正相关(P<0.05)。冗余分析(redundancy analysis)结果表明,环境因子显著影响访花昆虫多样性,但不同测度之间存在一定差异。温度和湿度均与Pielou均匀度指数呈正相关,与Shannon-Wiener多样性指数、Margalef丰富度指数和Simpson优势度指数呈负相关;弱干扰和中干扰程度对访花昆虫多样性影响最小,科学管理农牧活动是保护访花昆虫多样性的关键。
Aim Our aim is to clarify the relationship between diversity and community structure of flower-visiting insects and their habitat type,disturbance degree,and altitude in the Yanshan area.Methods Throughout July-August of 2019 and 2020,we collected flower-visiting insects in five habitats,including wetland,forest,shrub,grassland and farmland,with different gradients of 0-1,200 m above the sea level by using the method of transects and light lures.Result A total of 1,306 flower-visiting insects were collected,belonging to 153 species,44 families,and 7 orders,among which Lepidoptera had the largest number of species and Hemiptera had the largest number of individuals.The diversity of flower-visiting insects is highest in the shrub cluster.The Shannon-Wiener,Margalef,and Simpson indices are the highest in the middle and low altitudes of 200-400 m.The results of bivariate regression indicate that the Shannon-Wiener and Margalef indices are positively correlated with precipitation in the warmest season and annual precipitation respectively(P<0.05).Redundancy analysis(RDA)demonstrated that environmental factors significantly affected the diversity of flower-visiting insects,but there was some variation among different measures.Temperature and humidity are positively correlated with the Pielou index and negatively correlated with the Shannon-Wiener,Margalef,and Simpson indices.The results further indicate that scientific management of husbandry activities is the key to protecting the diversity of flower-visiting insects.Conclusion Scientific management of husbandry activities is the key to protecting the diversity of flower-visiting insects.
