Typical urban inland lake aquatic ecosystem health assessment:a case study of Guozheng lake in Wuhan city
摘要
Abstract
Conducting systematic assessments of the ecological health status of complex urban lakes under significant human disturbance is a crucial foundation for carrying out ecological restoration and biodiversity recovery effort.The research area is Guozheng Lake in Wuhan,which is the largest sub-lake of East Lake.The study involved analyzing 18 sampling points across the lake's northern,central,and southern areas to establish an evaluation system for aquatic ecosystem health.The system included elements such as water quality,aquatic life,and sediment microorganisms,and corresponding grading standards were developed.After conducting microscopic examinations,it was found that the benthic animal diversity in the northern part of Guozheng Lake was higher,with a Shannon-Wiener index of 2.37,which was higher than that in the central(1.98)and southern(1.33)lake areas.The northern area had the most arthropods and the least annelids,among which Tanypus chinensis was the dominant species;rotifers were the most numerous among planktonic animals,while diatoms and Cyanophyta were the most common among planktonic plants.Pearson correlation analysis showed that water temperature,TOC,COD,DO,and other water quality indicators significantly affected plankton diversity.High-throughput sequencing analysis found that the bacterial community abundance in the sediments of the northern lake area was less than in other areas.High-throughput sequencing analysis revealed that the bacterial community abundance in the sediments of the northern lake area was less than in other areas.The overall ecological health comprehensive index(EHCI)of Guozheng lake was 0.55,which was considered"fair"according to grading standards.However,the ecological health of the central and southern lake areas was weaker than that of the northern lake area.This research can provide precise control strategies for the ecosystem protection and restoration of specific lake areas,offering a basis for the management,protection,and restoration of lake ecosystems.关键词
