Water hyacinth blue breeds quickly, is easy to float and spread, and can quickly cover the water body, resulting in poor water transparency. Therefore, in natural waters, water hyacinth blue competes with other aquatic (floating and submerged) plants and algae for mineral nutrition, sunlight, etc. resources, thereby inhibiting the growth of other aquatic and algal organisms. In 2011, Wu Fuqin et al. tracked the results of Yunnan Dianchi Lake and also showed that water hyacinth could affect the photosynthesis of phytoplankton, submerged plants and algae by water environment quality and inhibit its growth. In addition, the outbreak of water hyacinth blue and its decay stage will consume a large amount of dissolved oxygen in the water body at the same time, and the space for reproduction of underwater animals such as fish will be reduced, and even a large number of fish will die. It is similar to changing the original food chain in the water body, thereby reducing the stability of the ecosystem in this water area.
