中文摘要：

螺类是软体动物腹足纲的通称,是湿地生态系统大型无脊椎动物的重要组成部分。湿地螺类在维持湿地生物多样性和复杂食物网结构,保障湿地物质循环和能量流动等方面具有重要的生态功能。从基本组成、生活型、功能群方面归纳了螺类群落结构特征;分析了螺类的时空分布格局;重点讨论了影响螺类群落结构的温度、盐度、底质等非生物因子和植被、物种间影响等生物因子以及人类对螺类的影响;概述了湿地演替过程中螺类群落的变化和螺类的环境指示功能。依据目前中国自然湿地螺类的研究特点和国际研究动态,展望了未来我国螺类群落的生态学研究的重点。

英文摘要：

Snails are gastropod mollusks. They play an important ecological role in wetland ecosystems by maintaining biodiversity, food web complexity, material cycling, and energy flow. In this review, we summarized the community composition and population structural characteristics of wetland snails including their abundant species, life forms, and functional groups. We then performed a detailed analysis of the spatial and temporal distribution of snails. We also discussed the main ecological and environmental factors that influence snail community structure and distribution patterns, including abiotic factors （ e.g., temperature, salinity, and sediment）, biological factors （ e.g., vegetation and interactions between species） , and human influences. We summarized the snail community changes during wetland ecosystem succession and identified potential indicator functions with respect to the wetland environment. Based on current research on snails in the natural wetlands of China and other global studies, we discussed further research necessary to understand wetland snail ecology in China.
