Problems solved by technology

[0004] In order to solve the technical problems existing in the prior art, the present invention provides a method for generating differentiated river patrol strategies, which can rationally allocate river patrol resources based on different river and lake water environment conditions, realize differentiated river patrol, and achieve water environment quality as a priority. Guided by promoting river chiefs to pay more attention to the state of rivers and lakes with poor water quality and their existing problems, and gradually increase the proportion of rivers and lakes with good water quality

Embodiment 1

[0045] This embodiment provides a device for generating differentiated river patrol strategies, such as figure 1 As shown, it includes a data cleaning module, a data model training module, a data visualization model, and a decision-making assistant generation module.

[0046] 1. The data cleaning module is used for data preprocessing and data cleaning, including down-sampling of river patrol problem data (also called river and lake problem data), so that the river patrol problem data and water quality monitoring data have the same data granularity, realizing data Alignment; code the water quality grade data as tag data, and divide it into three types of tags, namely five types of excellent, five types and five types of inferior; correlate the data with the ID of the river and lake as the associated field, and generate the river patrol path In the buffer zone, the drainage type data of drainage households, river patrol problem data and water quality grade data are fused to form...

Embodiment 2

[0103] Based on the same inventive concept, this embodiment provides a method for generating differentiated river patrol strategies. The decision-making rationality of river patrol resource allocation needs to be supported by a data model. As well as water service data such as drainage household data, machine learning technology is used to build a data model, complete the generation of prediction results and use it to formulate differentiated river patrol strategies, and guide the river patrol resource allocation plan and daily river patrol key tasks during the planning period. Specifically, rivers and lakes with water quality monitoring equipment are deployed to generate river and lake monitoring water quality data from the monitoring data collected by water quality monitoring points; rivers and lakes without water quality monitoring equipment deployment need to use the constructed random forest model to Predict and evaluate the water quality of rivers and lakes with water dat...

Abstract

The invention relates to a water affair engineering and environmental engineering technology, in particular to a differential river patrol strategy generation method and device, and the device comprises a data cleaning module which is used for data preprocessing, data cleaning and sample filtering to obtain a clean sample set; a data model training module which is used for training and evaluating a random forest model by using a clean sample set so as to predict river and lake water quality grades, carrying out clustering analysis on all rivers and lakes in a target window period by using a Gaussian hybrid clustering model, and expanding the training sample set through a label propagation technology; a model prediction and data visualization module which is used for predicting the river and lake water quality through a random forest model to obtain corresponding river and lake water quality grade information, and is used for evaluating a replacement feature important value of a river and lake patrol sorting score; and a decision-making auxiliary generation module which is used for formulating a differentiated river patrol strategy by combining the river-lake water quality grade information and the river-lake river patrol sorting score. River patrol resources can be reasonably distributed based on different river and lake water environment conditions, and differential river patrol is achieved.

Description

technical field [0001] The invention relates to the technical fields of water engineering and environmental engineering, in particular to a method and device for generating differentiated river patrol strategies. Background technique [0002] The comprehensive implementation of the river chief system is an inherent requirement for implementing the concept of green development and promoting the construction of ecological civilization. It is an effective measure to solve complex water problems and maintain the healthy life of rivers and lakes. It is an institutional innovation to improve the water governance system and ensure water security. It is the main job of the "river chief" to carry out river and lake inspections and promptly discover and promote the resolution of river and lake water pollution and water environment problems. [0003] At present, river chiefs use a "no difference" patrol strategy, that is, river chiefs at the same level are required to carry out river a...
