摘要
白洋淀是华北平原最大的浅水湖泊生态系统。近年,在自然和人为等多因素影响下,入淀流量锐减、生态空间萎缩、生态系统功能下降等问题频频出现。为化解白洋淀生态危机,水利部、河北省先后组织了近50次生态补水,重塑了湖泊水文情势、改善了水体质量,对生态系统结构和关键过程产生了深远影响。在分析现有生态补水生态响应研究的基础上,剖析了目前存在的主要问题,阐明了基于系统层面探究生态响应的必要性,提出了基于食物网稳定性探究生态补水对湖泊生态系统结构和功能的驱动机制、影响规律的总体框架,为浅水湖泊生态系统修复和多源生态补水机制建立提供科学支撑。
The Baiyangdian Lake is the largest shallow lake in the North China Plain.However,under the multiple pressures of natural and human activities,the lake inflow decreased sharply,the ecological space shrank,and the ecosystem function declined.To save the ecological crisis of the Baiyangdian Lake,the Ministry of Water Resources and Hebei Province organized nearly 50 ecological water supplements,which reshaped the lake's hydrological regimes,improved water quality,and profoundly impacted the ecosystem structure and ecological processes.We summarized the main problems and recommended the necessity of exploring ecological responses at the system level,and forwarded the general framework of exploring the mechanisms of ecological water supplement on the structure and functions of lake ecosystems via food web stability.The study supports the restoration of shallow lake ecosystems and the establishment of a multi-source ecological water supplement project.
