长江中游高山泥炭湿地在区域生态安全和生物多样性保护方面具有举足重要的地位,有壳变形虫是一类在泥炭湿地表面大量生活的原生动物,它们对环境变化敏感,是环境变化的有效指示器。泥炭湿地的现代生态学调查已经表明,有壳变形虫群落对泥炭的表面湿度和水文条件具有灵敏的响应,但是与其他环境条件如水化学因子的关系尚不明确。本文主要调查了长江中游高山泥炭湿地有壳变形虫群落特征及其对水化学因子的响应,发现Cr和Mn对有壳变形虫的群落组成具有较为明显的影响。有壳变形虫的群落组成在不同湿地间有一定差异,这种空间上的差异分布可能反映了湿地的不同类型、发育阶段和人类活动等信息。有壳变形虫可为湿地的科学管理、动态监测和可持续发展等方面提供有效的指示信息。
Alpine peat wetlands in the middle reaches of the Yangtze River play an important role in regional ecological security and biodiversity conservation. Amoebae are a group of protozoa living on the surface of peat wetlands. They are sensitive to environmental changes and are effective in environmental change Indicator. Modern ecological investigation of peat wetlands has shown that the crustaceans community has a sensitive response to peat surface moisture and hydrological conditions, but the relationship with other environmental conditions such as hydration factors remains unclear. In this paper, we investigated the characteristics of crustaceans and their responses to water chemistry in the mountainous mid-stream alpine peat wetlands. It was found that Cr and Mn had a significant influence on the composition of crustaceans. The composition of crustaceans in different wetlands have some differences. The spatial distribution may reflect the different types of wetlands, developmental stages and human activities. Crayfish provides an effective indicator of the wetland’s scientific management, dynamic monitoring and sustainable development.
