Artificial water bodies in Central Asia offer unique environments in which to study plankton diversity influenced by topographic barriers. However, the complexity of these ecosystems and limited comprehensive studies in the region challenge our understanding. In this study, we systematically investigated the water environment parameters and phytoplankton community structure by surveying 14 artificial waters on the southern side of the Altai Mountains and the northern and southern sides of the Tianshan Mountains in the Xinjiang region. The survey covered physical and nutrient indicators, and the results showed noticeable spatial differences between waters in different regions. The temperature, dissolved oxygen, total nitrogen, and total phosphorus of artificial water in the southern Altai Mountains vary greatly. In contrast, the waters in the northern Tianshan Mountains have more consistent physical indicators. The results of phytoplankton identification showed that the phytoplankton communities in different regions are somewhat different, with diatom species being the dominant taxon. The cluster analysis and the non-metric multidimensional scaling (NMDS) results also confirmed the variability of the phytoplankton communities in the areas. The variance partitioning analysis (VPA) results showed that climatic and environmental factors can explain some of the variability of the observed data. Nevertheless, the residual values indicated the presence of other unmeasured factors or the influence of stochasticity. This study provides a scientific basis for regional water resource management and environmental protection.
中亚的人工水体提供了独特的环境，可用于研究受地形屏障影响的浮游生物多样性。然而，这些生态系统的复杂性以及该地区有限的综合研究对我们的理解提出了挑战。在本研究中，我们通过对新疆地区阿尔泰山南侧以及天山南北两侧的14个人工水域进行调查，系统地研究了水环境参数和浮游植物群落结构。该调查涵盖了物理和营养指标，结果显示不同区域的水域之间存在明显的空间差异。阿尔泰山南侧人工水体的温度、溶解氧、总氮和总磷变化很大。相比之下，天山北侧的水体物理指标更为一致。浮游植物鉴定结果表明，不同区域的浮游植物群落存在一定差异，硅藻种类是优势分类群。聚类分析和非度量多维标度（NMDS）结果也证实了这些区域浮游植物群落的变异性。方差分解分析（VPA）结果表明，气候和环境因素可以解释部分观测数据的变异性。然而，残差值表明存在其他未测量的因素或随机性的影响。本研究为区域水资源管理和环境保护提供了科学依据。
