摘要/Abstract

摘要： 通过测定辽宁省葫芦岛锌厂不同生境植物和主要消费者的碳、氮稳定同位素比值，研究冶金区不同消费者碳、氮稳定同位素组成及不同消费者之间的关系。结果表明：节肢动物δ¹³C、δ¹⁵N值的变化范围分别为-12.61‰~-29.63‰、1.73‰~9.94‰，变化幅度较大。研究区植物以C3植物居多，导致不同群落生境动物δ¹³C值较低；螳螂、蜘蛛δ¹⁵N比值高于其他动物；通过营养级模型计算可知不同消费者之间的关系，蝗虫、蚱蜢等草食性动物形成第二营养级，即初级消费者；第三营养级包括蜘蛛、螳螂，为次级消费者。

Abstract: By measuring the δ¹³C and δ¹⁵N ratios of plants and their main consumers in different habitats of Huludao Zinc Plant, Liaoning Province of Northeast China, this paper studied the relationships between the carbon and nitrogen stable isotopes composition of different consumers and the consumers. In the study area, the δ¹³C and δ¹⁵N values of arthropods had a greater variation range, being -12.61‰--29.63‰ and 1.73‰-9.94‰, respectively. The C3 plants were dominant, which led to the lower δ¹³C values of the animals in different habitats. The δ¹⁵N values of Argiope bruennichii and Paraten odera sinensis were higher than those of the other animals. According to the trophic model, herbivores (Locusta migratoria manilensis and Acrida chinensis) were at the second trophic level, i.e., the primary consumers, whereas A. bruennichii and P. odera sinensis were at the third trophic level, i.e., the secondary consumers.
