Wetland buffer area water ecological health evaluation method based on trend decision

Abstract

The invention discloses a wetland buffer area water ecological health evaluation method based on trend judgment, which comprises the following steps: S1, judging influence factors based on Meta analysis: setting retrieval keywords, collecting experimental observation data of potential influence factors, obtaining key influence factors of water ecological health through environmental factor correlation analysis, and calculating the weight of the influence factors; s2, collecting index data; s3, establishing a prediction model based on machine learning; and S4, trend judgment: inputting the predicted value of each key influence factor and the influence weight of different influence factor types into the water ecological health evaluation model to obtain the water ecological health condition after n years in the future, and taking the water ecological health condition as the prediction evaluation of the current water ecological health state. According to the method, the influence factors which are high in correlation and sensitive in influence can be obtained, limitation caused by regional scale research is eliminated to the maximum extent, the current water ecology health is evaluated from the future perspective, and the development trend of the current water ecology health state and the current state can be better reflected.

Description

technical field [0001] The invention belongs to the field of water ecological health evaluation, and mainly relates to a water ecological health evaluation method of wetland buffer zone based on trend judgment. Background technique [0002] Wetland refers to the area where the surface is too wet or often accumulates water and grows wetland organisms. Wetland ecosystem is a unified whole composed of wetland plants, wetland animals, microorganisms and their environment. Wetlands have multiple functions: protect biodiversity, regulate runoff, improve water quality, regulate microclimate, provide food and industrial raw materials, and provide tourism resources. Water quality evaluation refers to the selection of corresponding water quality parameters, water quality standards and evaluation methods according to the evaluation objectives, to evaluate the quality and utilization value of water bodies and the effect of water treatment. Water quality assessment is a basic work for ...

AI Technical Summary

Problems solved by technology

In the selection of evaluation factors, most of the influences of a single type are considered, which has a one-sided impact on the overall water ecological health evaluation. weight, leading to the loss of parameter information expression

In addition, in terms of forecasting, machine learning is an advanced and efficient means, but for machine learning, a common problem is that its predictions are often not based on physical meaning

That is to say, the algorithm is only looking for the correlation between the input and the output, but sometimes, this correlation may be "false", or may give wrong results, which can be directly used in the evaluation of water ecological health. results in algorithmic models that cannot handle changes in the relationship between inputs and outputs
