Abstract

Abstract With the rapid development of economy, the rapid growth of population and the accelerating pace of urbanization, water pollution is becoming more and more serious. Most urban parks and lakes are polluted and seriously eutrophic, losing their due landscape ecological value. This study takes lake A in a city as an example, based on the perspective of geographical environment and relying on the ecological restoration project of Lake A. This paper analyzes the changes of physical and chemical indexes and biological indexes of water quality with time series through the whole process tracking and monitoring of ecological restoration project; Through the evaluation of eutrophication of lake A, the test indexes and sensitivity of ecological restoration effect are studied. Combined with the current eutrophication evaluation system, new water quality test parameters are proposed to diagnose and evaluate the water quality of shallow eutrophic lakes after ecological restoration. The results show that through the implementation of ecological restoration project, the water quality of lake A has been well improved and basically stabilized at the class IV standard of surface water; The dominant species of phytoplankton community changed from large-scale colony algae to small-scale individual algae, the algal biomass was well controlled and the eutrophication status was improved.
