Investigation of water environment monitoring and evaluation based on water ecological function zoning

Abstract

AbstractThis paper expounds the establishment of the water environment evaluation system and the water environment monitoring (EM) countermeasures and discusses the water environment security evaluation index system. The establishment of a water environment-sensitive monitoring area was proposed, and the establishment of a water EM network system was studied. The construction of water EM and evaluation based on the entropy weight method was carried out, and the analysis of water EM and evaluation elements of ecological function zoning were proposed. The research was carried out from two aspects, namely the problems solved by water EM and evaluation based on water ecological function zoning, and the water environment evaluation system based on water ecological function zoning. According to the experiment and investigation, the entropy weight method was introduced into the framework of the water EM and evaluation system, and a new water EM and evaluation system was constructed, which was 19% more satisfactory than the traditional water EM and evaluation system.
