摘 要:蚂蚁作为草地生态系统重要组分之一,其种类和分布、筑巢和采食等对草地植被演变和土壤特性变化起重要作用。本文综述了中、高海拔不同草地类型中,蚂蚁的种类及分布、蚂蚁与草地动物的关系及蚂蚁对草地植被和蚁丘土壤理化特征的影响。结果显示:(1)蚂蚁适应性强,分布广,各类草地均有分布,但不同草地类型中蚂蚁种类有所不同;(2)蚂蚁作为草地生态系统的消费者,与其他草地动物有竞争、捕食与被捕食、共生与寄生等关系,这对草地健康的保持有利有弊,但最终维持着草地生态系统的平衡;(3)蚂蚁筑巢降低草地物种多样性,改变草地植物群落结构;(4)蚂蚁的挖掘、搬运、排泄和掩埋等增加蚁丘土壤养分和微生物活性,增加土壤孔隙度而降低容重,但其对土壤水分的影响因草地类型不同而异。为深入揭示蚂蚁在草地生态系统中的作用,未来还需开展如下研究:蚂蚁筑丘及采食活动对草地植被微斑块形成的作用机制及对演替的影响;蚂蚁在草地虫害防控中的作用;蚂蚁分泌物如何影响草地土壤微生物群落的构成。Ant is one of important components of grassland ecosystem. The species, distribution, nesting and feeding of ants play an important role in vegetation succession and soil characteristics in grasslands. We summarized the species and distribution of ants in different type grasslands in middle and high altitude areas, relationship between the ants and other animals, the effects of the ants on plant community composition and physical and chemical characteristics in ant nest soil. The results indicated that:(1) The ants were high adaptability and widely distributed in each of grassland, and the species was different among different grasslands;(2) Ants acts as consumers of grassland ecosystems, the relationships between ants and other animals exhibited competition, predation and prey, symbiosis and parasitism, all of these can benefit or harm the health of grassland, which will ultimately maintains the balance of the grassland ecosystem;(3) Ants reduced plant species diversity and changed the plant community structure by building nest;(4) Ants increased the nutrients and microbial activity of ant nests soil by digging, transporting, excreting and burying, and also increased porosity and reduced bulk density of nest soil, while the effect of ants on the soil moisture varied from the different grasslands. In order to deeply reveal the effects of ants on grassland ecosystem, the following studies needed to be carried out in the future: effects of anthill formation on the grassland succession and mechanisms of feeding and nesting activities of ants on the formation of grassland vegetation micropatches;the role of ants in controlling and prevention of grassland pest;how do the ant secretions affects the composition of grasslands soil microbial communities.
