本研究以南水北调东线重要蓄水湖之一的微山湖为研究对象，研究了2012年4个季节中大型无脊椎动物群落结构和群落-环境关系在河口、运河和湖区三个典型栖息地的变化。共记录到72个类群，隶属于3门9纲24科，其中耐性寡毛类和摇蚊为优势类群。环境条件和大型无脊椎动物群落在空间和时间尺度上明显分离。群落结构表现出明显的空间变化，但比季节变化更大，在排序图上，三个区域的位置明显分开。通过双向聚类分析，与时间尺度相比，保留了更多的指示物种来解释区域差异。不同的环境变量对不同季节的大型无脊椎动物群落有显著的区分作用，其中pH是唯一保留在所有模型中的变量。本研究为南水北调中线前典型调水蓄水湖的环境特征和大型无脊椎动物群落提供了有用的背景信息。在SNWD运行后，我们可以预见跨流域调水(IBWT)，通常伴随着水位上升、营养格局变化和生物群演替，将严重影响受水区。因此，我们提出了南水北调中线工程的几点管理策略：(1)及时收集目标和详细的数据；(2)政府应防止水污染，并采取有效措施保护水环境；(3)环境评估与IBWT规划的其他方面应协调一致；(4)应统筹考虑不同流域的水资源规划、调度和分配；(5)在工程运营过程中应关注物种的迁徙和入侵。
In the present study, we choose the Weishan Lake, one of important water transfer and storage lakes on the eastern route of the South-to-North Water Diversion Project (SNWD) in China, to clarify how the community structure and assemblage-environment relationships of macroinvertebrates varied across three typical habitats (the River Mouth, Canal and Lake regions) over the four seasons in 2012. A total of 72 taxa belonging to 3 phyla, 9 classes and 24 families were recorded, with tolerant oligochaetes and chironomids as the dominant taxa. The environmental conditions and macroinvertebrate assemblages were clearly separated at spatial and temporal scales. Assemblage structure showed both significant but larger spatial than seasonal variations, with a clear separation of sites from three regions in an ordination plot. Compared to the temporal scale, more indicator species were retained to be responsible for the regional differences according to the two-way cluster analysis. Different environmental variables were significant for distinguishing macroinvertebrate assemblages among four seasons, and among them, pH was the only variable which was retained in all models. Our study provided useful background information of environmental characteristics and macroinvertebrate communities in a typical water transfer and storage lake before the water transfer of the SNWD. After the operation of SNWD, we envisage inter-basin water transfer (IBWT), which is usually accompanied by water level rise, nutrient pattern change and biota succession, will seriously affect recipient basins. Therefore, we propose several management strategies for SNWD: (1) target and detailed data should be collected on a timely basis; (2) government should prevent water pollution and adopt effective measures to protect the water environment; (3) the environmental assessments and other aspects of IBWT planning should be coordinated; (4) an overall consideration of different basins should be given to achieve a greater range of water resources planning, scheduling, and allocation; and (5) the migration and invasion of species should be of concern during the operation of the project.
