A monitoring point optimization method for lake water ecological effects of water diversion projects

Abstract

The invention discloses a monitoring point optimization method for lake water ecological effects of a water diversion project, which belongs to the technical field of environment and ecological hydraulics. The method includes the following steps: (1) defining the geographical scope of the water ecological impact monitoring of the water diversion project lake; (2) setting the monitoring points of the water diversion channel and the water receiving lake; (3) determining the monitoring time and frequency; Biome indicators and abiotic physical and chemical indicators are used as monitoring indicators to characterize the impact of water ecology; (5) Based on the Euclidean distance coefficient of abiotic physical and chemical indicators and the Bray Curtis similarity coefficient of aquatic biome indicators, clustering and optimization of monitoring points The number of bits and the frequency of monitoring. The monitoring index involved in the invention is easy to obtain, and is convenient for large-scale implementation and application. This method can provide an effective optimization method for the water diversion project to monitor the water ecological impact of large-scale eutrophic lakes and frequency settings, and reduce the monitoring workload.

Description

technical field [0001] The invention belongs to the technical field of environment and ecological hydraulics, and in particular relates to a monitoring point optimization method for lake water ecological effects of a water diversion project. Background technique [0002] In recent years, with the increasingly serious drinking water and ecological crisis caused by the outbreak of cyanobacteria blooms in large eutrophic lakes such as Taihu Lake, Chaohu Lake and Dianchi Lake, the water diversion control project for large eutrophic lakes has attracted the attention of relevant departments and has become Important water conservancy engineering measures to alleviate cyanobacterial bloom disasters. Unlike small lakes, the effect of water diversion control projects on large-scale eutrophic lakes on lake ecology and environment improvement is affected and restricted by various factors. It is difficult to obtain ideal results in the short term, and water diversion control projects oft...

Problems solved by technology

Unlike small lakes, the effect of water diversion control projects on large-scale eutrophic lakes on improving lake ecology and environment is affected and restricted by many factors. It is difficult to obtain ideal results in a short period of time, and water diversion control projects often need to be operated on a regular basis.
