As an important part of urban infrastructure, urban water system is of great and far-reaching significance for ensuring urban flood control and waterlogging safety, protecting ecological environment and building livable homes. Taking the urban water system of Nantong as an example, Nantong Water Resources Bureau issued Revision of Nantong Urban Water System Planning in 2017, and put forward the construction of the "two circles, eight lakes and nine veins" water system layout, giving new vitality to the urban water system. In view of problems existing in newly excavated artificial landscape lakes, such as fragile water ecosystem, strong eutrophication trend, poor environmental sensory effect and unsatisfactory water landscape effect, it is urgent to study the in-situ water ecological restoration technique of "algae-controlling zooplankton j submerged plant community" to build a "gran-type clear water" ecosystem for artificial landscape lakes, so as to improve the water sensory index and self-purification ability and finally realize the double improvement of "sensory effect and water quality" of artificial landscape lakes.
