Description

Technical Field

[0001] This invention belongs to the field of water environment analysis and relates to correlation analysis technology, specifically a correlation analysis method and system for water environment analysis. Background Technology

[0002] Water pollution is caused by harmful chemicals that reduce or eliminate the usability of water, polluting the environment. Whether or not the water is drinking water, it severely impacts the health of nearby residents. Therefore, it is crucial to identify the cause of water pollution as soon as it occurs. In similar water environments, the causes of pollution often exhibit consistency. Therefore, analyzing data from similar water environments can help determine the current causes of pollution. However, current analyses based on historical data largely rely on experience-based judgments and lack quantitative analysis, making it difficult to promptly identify the true causes of water pollution.

[0003] Therefore, a correlation analysis method and system for water environment analysis is proposed. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a water environment analysis method and system based on correlation analysis. This method and system includes: a water environment data collection module to pre-collect all historical basic data of the water environment; a water environment classification module to classify the water environment according to its size and flow pattern; a water environment pollution survey module to analyze the pollution status of the water environment; a similar water environment screening module to initially screen water environments with similar pollution status from historical basic data of similar water environments based on the current pollution status; a pollution cause analysis module to obtain the water environment with the highest environmental data similarity from the water environments with similar pollution status; and using the pollution cause of the most similar water environment as an investigative clue to investigate the pollution cause of the current water environment; thus improving the efficiency of water pollution cause investigation.

[0005] To achieve the above objectives, an embodiment of the first aspect of the present invention provides a water environment analysis method based on correlation analysis, comprising the following steps:

[0006] Step 1: The water environment data collection module collects all historical basic data on the water environment in advance;

[0007] Step 2: The water environment classification module classifies the water environment according to its size and flow pattern;

[0008] Step 3: The water environment pollution survey module analyzes the pollution status of the water environment;

[0009] Step 4: The similar water environment screening module, based on the current water environment pollution status, initially screens out water environments with similar pollution status from historical basic data of similar water environments;

[0010] Step 5: The pollution cause analysis module obtains the water environment with the highest environmental data similarity from water environments with similar pollution conditions; and uses the pollution cause of the most similar water environment as an investigation clue to investigate the pollution cause of the current water environment;

[0011] The historical basic data of the water environment includes historical environmental data, pollution data, and causes of pollution.

[0012] The historical environmental data refers to the surrounding environmental factors that affect water quality when each water environment experiences water pollution.

[0013] The pollution data includes the manifestations and severity of water pollution in each water environment.

[0014] The causes of pollution are the reasons for each instance of water pollution in each water environment.

[0015] The water environment classification module classifies water environments in the following way: based on the geographical location, water environment, size of the water body, and water flow, water environments are divided into four types: rivers, lakes, and seas.

[0016] The water environment pollution survey module analyzes the pollution status of the water environment by having personnel conduct pollution surveys at regular intervals T. The survey content includes current environmental data and pollution status data of the water environment. The time interval T is set based on practical experience.

[0017] The similar water environment screening module identifies water environments with similar pollution levels through the following steps:

[0018] Step S1: Obtain the water body type of the current surveyed water environment; mark the water body type as S;

[0019] Step S2: Obtain historical basic data of water environment for all water bodies of type S;

[0020] Step S3: Based on the water pollution performance in the current water pollution data, obtain water environment basic data with similar pollution performance from the pollution data in the historical basic data of similar water environments;

[0021] The method for judging similar pollution performance is as follows: a similarity threshold K is set in advance based on actual experience, and the current water environment pollution performance and the historical similar water environment pollution performance are quantified; the quantification method is based on the actual pollution performance; similar pollution performance is defined as the difference between the current water environment quantified water pollution performance and the historical water environment quantified water pollution performance is less than the similarity threshold K.

[0022] The pollution cause analysis module obtains the water environment with the highest environmental data similarity through the following steps:

[0023] Step P1: Quantify each item in the current water environment and the water environment data after preliminary screening; and perform normalization processing.

[0024] Step P2: For each type of water pollution manifestation, assign a weight to each item in the environmental data according to the degree of influence of each item on the manifestation; label each environmental data item as m, label the weight of the current environmental data m as Wm, and label the value of the current environmental data m as Vm; label each water environment after preliminary screening as i, label the weight of the environmental data m of water environment i as Wmi; label the value of the environmental data m of water environment i as Vmi;

[0025] Step P3: Calculate the similarity Ci between the environmental data of water environment i and the current water environment data; the formula for calculating Ci is Ci = ∑ m Wmi*|Vmi-Vm|).

[0026] To achieve the above objectives, an embodiment of the second aspect of the present invention provides a water environment analysis system based on correlation analysis.

[0027] It includes a water environment data collection module, a water environment classification module, a water environment pollution survey module, a similar water environment screening module, and a pollution cause analysis module; the modules are connected electrically.

[0028] The water environment data collection module is used to collect all historical basic data of the water environment in advance; and send the collected historical basic data to the similar water environment screening module and the pollution cause analysis module.

[0029] The water environment classification module is used to classify water environments according to their size and flow patterns, and then send the classification results to the similar water environment screening module.

[0030] The water environment pollution survey module is used to analyze the pollution status of the water environment and send the analysis results to the similar water environment screening module and the pollution cause analysis module.

[0031] The similar water environment screening module is used to initially screen out water environments with similar pollution conditions from historical basic data of similar water environments based on the current pollution status of the water environment; and send the preliminary screening results to the pollution cause analysis module.

[0032] The pollution cause analysis module is used to obtain the water environment with the highest environmental data similarity from water environments with similar pollution conditions; and to use the pollution cause of the most similar water environment as an investigation clue to investigate the pollution cause of the current water environment.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] This invention collects historical environmental and pollution data for various water environments in advance and quantifies the environmental and pollution data; it then performs correlation analysis between the current water pollution situation and the pollution situation of other water environments in the past to find similar historical water pollution situations; by quantifying and analyzing the data, it effectively utilizes historical data and improves the efficiency of water pollution cause investigation.

[0044] It is understandable that water pollution is caused by harmful chemicals that reduce or eliminate the usability of water, thus polluting the environment. Regardless of whether the water is drinking water or not, it will seriously affect the health of nearby residents. Therefore, when water pollution occurs, it is necessary to find the cause of the pollution as soon as possible. In similar water environments, the causes of water pollution are often consistent. Therefore, analyzing data from similar water environments can help to analyze the causes of current water pollution.

[0045] In a preferred embodiment, the historical basic data of the water environment includes historical environmental data, pollution data, and causes of pollution;

[0059] Step P3: Calculate the similarity Ci between the environmental data of water environment i and the current water environment data; the formula for calculating Ci is Ci = ∑ m Wmi*|Vmi-Vm|).
