Health Assessment of Dali Lake based on The Benthic Macroinvertebrate Biotic Integrity Index
In August 2021,a study on the health of Dali Lake was carried out by investigating benthic macroinverte-brates at seven different sampling locations.This study also led to the creation of the benthic index of biotic integrity(BIBI)evaluation system.The findings revealed the presence of six different genera and species of benthic macroin-vertebrates in Dali Lake,belonging to two phyla,three orders and five families.The BMWP and FBI indices,ob-tained through range test,discriminatory power and Pearson correlation screen,formed the basis of BIBI's assess-ment system for Dali Lake.Calculations indicated that the macrobenthos biological integrity index in Dali Lake was 0.83,while the benthic index of bioticintegrity had a score of 74.45.Thus,the aquatic ecosystem of Dali Lake in 2021 was deemed sub-healthy.
