Fuzzy Comprehensive Evaluation of Qinghe Water Environment Based on Biometric Index of Macrobenthos Community Biological Index

Abstract

With the rapid improvement of my country's industrialization process, the unreasonable use of water resources, deforestation, vegetation destruction and other phenomena frequently occur, especially the poor public awareness of environmental protection, lack of awareness of the protection of water resources in the Qinghe River, etc. Decline. Studying the Qinghe water environment based on the macrobenthos community biological index can provide a strong scientific basis for the management of the Qinghe water environment. The purpose of this paper is to comprehensively evaluate the water environment of Qinghe River based on the biometric index of macrobenthos community. During the experiment, samples were collected and analyzed for the sample collection method, namely direct hand net sampling in shallow rivers and foot manipulation in deeper water. Using the BI index method, the spatial distribution of macrobenthos species and the fuzzy comprehensive health assessment of the Qinghe water environment were investigated and analyzed.
