Embodiment 1

[0046] This example further elaborates a method for optimizing lake water ecological effect monitoring points of the water diversion project in conjunction with the "Diversion of the River to Taitai" project in the Taihu Lake Basin. The specific process is as follows:

[0047] (1) Define the scope of monitoring

[0048] The project of "Diverting the Yangtze River to Taihu Lake" diverts the Yangtze River into Taihu Lake through the Wangyu River Diversion, aiming to ensure the water supply of Taihu Lake and suppress the occurrence of cyanobacteria blooms in Taihu Lake. The water delivery river of the water diversion project is Wangyu River, and the lake directly receives water The water receiving area is Gonghu Bay. Accordingly, it is determined that the monitoring scope of this embodiment is the upstream section of Wangyu River Wangting Water Conservancy Project and Gonghu Bay.

[0049] (2) Set monitoring section or point

[0050]According to the layout principles of river a...

Abstract

The invention relates to a method for optimizing an ecological effect monitoring point position of diversion project lake water, belonging to the technical field of environmental and ecological hydraulics. The method comprises the following steps: (1) defining the geographical range of ecological impact monitoring of the diversion project lake water; (2) arranging the monitoring point positions ofa diversion riverway and a water receiving lake; (3) determining monitoring time and frequency; (4) determining an aquatic biocenosis index and a non-biological physicochemical index as monitoring indexes for representing water ecology impact; and (5) clustering and optimizing monitoring point position number and monitoring frequency based on the Euclidean distance coefficient of the non-biological physicochemical index and the Bray-Curtis similarity coefficient of the aquatic biocenosis index. The monitoring index related to the method is easy to obtain, and wide-range implementation and application are convenient. According to the method, an efficient optimization method can be provided for large-scale water receiving eutrophication lake water ecology impact monitoring point position arrangement and frequency setting of diversion works, and the monitoring workload is reduced.

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...
