Embodiment 1

[0042] This embodiment is to evaluate the health of the water ecosystem of a lake in northern China (replaced by WL lake below), and the evaluation process is as follows figure 1 As shown, the specific evaluation process is as follows:

[0043] (1) Investigation and analysis of lake water environment.

[0044] In the spring, summer and autumn of 2014, a total of 53 sampling points were set up in the lake area to collect water samples and monitor the physical indicators of the lake: temperature (T), turbidity (Turb), transparency (SD), conductivity (TDS), suspended solids (SS ); chemical indicators: pH, dissolved oxygen (DO), chemical oxygen demand (CODcr), permanganate index (COD Mn ), ammonia nitrogen (NH3 -N), total nitrogen (TN), total phosphorus (TP), five-day biochemical oxygen demand (BOD 5 ), fluoride (F - ), volatile phenol (VF); toxicity indicators: acute toxicity (Acutoxic), comprehensive toxicity (Comtoxic); hygiene indicators: total number of bacteria.

Abstract

The invention discloses a health assessment method based on a lake water ecosystem, pertaining to the technical field of environment protection. The method comprises following steps: firstly, investigating and analyzing lake water environment and lake water aquatic organism, and utilizing canonical correspondence to analyze and explore the relations between aquatic organism distribution and environment factors; further determining candidate indictors, determining assessment indictors, determining assessment indictor weight, establishing assumable indictor system, calculating health comprehensive indictors of the lake water ecosystem and assessing the health state of the lake water ecosystem. The health assessment indictor system of the lake water ecosystem is utilized for scientific assessment of the healthy condition of the lake water ecosystem and helps objectively reflect the environment of lake water and the health condition of aquatic communities.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a health evaluation method based on lake water ecosystems. Background technique [0002] In recent years, due to the increasing intensity of water resources utilization and pollutant discharge, the water ecological environment problem has become one of the most important environmental problems in my country. Compared with the 20th century, water environmental problems have undergone significant changes in terms of nature, scale and impact. Water environmental pollution has developed from single pollution to compound pollution, interweaving of various old and new pollutants, and the complex situation of coupling effects of pollution and non-pollution. The problems have become more complex and the risks are greater. The current water quality evaluation methods are far from meeting the needs of water environment management. It is the development trend ...
