摘要:
伴随着举世瞩目的三峡工程全面竣工,三峡水库于2010年正式进入年水位落差达30 m的正常运行阶段.水库湖沼学可为环境友好型大坝建设和水库可持续管理提供科学依据.本文在三峡成库8 a以来生态系统长期监测与研究的基础上,对三峡水库水环境现状进行了归纳和总结,分析了水环境动态的时空异质性、水库纵向分区与群落组成、垂向分布及藻类水华的成因和动态,并对三峡水库藻类水华预警与生态-水文调控机制展开了论述.最后,本文尝试给出以下两方面的展望:1)大型水库湖沼学观测研究应有长期的策略;2)近期研究应重点关注水华暴发水动力学机制的量化和水华预警模型及生态水力调度平台的耦合.

Abstract:
As the final completion of the world-famous Three Gorges Project, the Three Gorges Reservoir(TGR) came into a normal operation stage since the year 2010, with an annual water level fluctuation of 30 m. Reservoir limnology can provide a scientific basis for environment-friendly dam construction and reservoir sustainable management. On the basis of long-term monitoring and investigation on the TGR ecosystem for 8a, this paper described the current status of aquatic environment in the reservoir, and elaborated the spatial-temporal heterogeneity of water environmental dynamics, longitudinal zonation and biological community structure, vertical distribution, and forming and tendency of algal bloom of the TGR. The early warning of algal bloom and eco-hydrological regulation mechanism were also analyzed. Two perspectives of ecological research on TGR were finally pointed out in the paper:1) Limnological observation and research in the large reservoir should have a long-term strategy; 2) Research in near future should focus on the quantification of hydrodynamics mechanism on algal bloom, and the coupling of early warning models of algal bloom and eco-hydraulic regulation platform.
