| 摘 要： | 为了解广西红水河流域大型底栖动物群落结构状况,于2013年春季(4月)、夏季(7月)、秋季(11月)对红水河流域13个采样点进行了调查. 采集并鉴定出大型底栖动物179个分类单元,隶属7纲20目66科. 其中水生昆虫种类数所占比例最高(79.3%),软体动物次之(15.1%). 各季节大型底栖动物个体数表现为夏季>春季>秋季. 依据大型底栖动物群落组成相似性,利用聚类分析将13个采样点分为2组. 组1采样点主要分布于岩滩水库和红水河干流,组2采样点主要分布于各个支流,2组采样点在无度量多维标定排序轴上分布差异明显. 指示种分析结果显示,组1指示种为马速达多足摇蚊(Polypedilum masudai),组2指示种以宜兴似动蜉(Cinygmina yixingensis)敏感物种为主. 功能摄食类群研究结果表明,红水河大型底栖动物以刮食者占绝对优势,其个体数占总个体数的比例为36.45%,撕食者(6.15%)和杂食者(3.25%)所占比例较小. 单因素方差分析结果显示,其他类(包括软甲纲、蛭纲以及蜱螨亚纲)和捕食者相对丰度存在季节性差异(P<0.05). T检验结果表明,收集者、捕食者和杂食者存在组间差异(P<0.05).

| Abstract: | To explore the status of macroinvertebrate communities and their response to ecological changes, an investigation was carried out in 13 sections of Hongshui River in Guangxi Province in April, July and November 2013. A total of 179 species were identified, belonging to 66 families, 20 orders and 7 classes. The dominant class of macroinvertebrate was Insecta (79.3%), followed by Gastropoda (15.1%). Macroinvertebrates were most abundant in summer, followed by spring and autumn. The results of cluster analysis (CA) showed that the 13 sections were divided into two groups. The first group was distributed in Yantan Reservoir and the main stream of Hongshui River, while the second group was located in the tributaries. According to non-metric multi-dimensional scaling analysis (NMDS), two clusters were separated into different areas at the ordination axes. Indicator value analysis was conducted to identify the indicator species for different clusters. Polypedilum masudai was the indicator of cluster 1 and Cinygmina yixingensis, a sensitive species, was the main indicator of cluster 2. The results of functional feeding groups showed that scrapers were the main components in Hongshui River, with its proportion being 36.45%, followed by shredders (6.15%) and omnivores (3.25%), which only accounted for small percentages. The results of one-way ANOVA showed that predator and other classes which consist of Malacostraca, Hirudinea and Acari had seasonal differences. The results of independent-samples T test showed that collector-gatherers, predators and omnivores had significant differences in group 1 and group 2. |
