Problems solved by technology

However, this patent is mainly an auxiliary processing technology for remote sensing information to participate in eutrophication evaluation, which can only replace the eutrophication identification method based on laboratory sample analysis, and does not have fully automated functions from automatic water quality monitoring to intelligent identification , there is no need to consider the impact of geographical attributes on different types of lakes in the discriminant method

Embodiment 1

[0043] This embodiment provides an intelligent method for judging the nutritional status of lakes and reservoirs, the process is as follows figure 1 shown, follow the steps below:

[0044] (1) In the target waters of lakes and reservoirs, measure water body transparency, chlorophyll a, total phosphorus and total nitrogen concentration; the frequency of measurement is not less than once per week, and each measurement operation is not less than 4 weeks. Take the average value of the series;

[0045] (2) In the target water area of ​​lakes and reservoirs, conduct surveys and surveys on geographical attributes such as longitude, latitude and elevation, query the "World Map" and "World Climate Zone Distribution Map" and determine the geographical divisions they belong to as "frigid zone" and "cold zone" according to the elevation. One of the "inland mountainous area", "inland plain area", "coastal area" and "arid and transitional area"; the following table shows the correspondence b...

Abstract

The invention belongs to the technical fields of environmental protection and comprehensive utilization of resources, and relates to an intelligent distinguishing system for nutritional status of lakes and reservoirs. The system includes: a data collection module, a data distinguishing module and a data dissemination module. The data distinguishing module includes: a water quality information pre-treatment module, a geographic zoning sort module, a distinguishing module based on the geographic zone, a neural network data drive analysis module and a result optimization module. The neural network data drive analysis module includes an input layer, a hidden layer and an output layer. The input layer has four input nodes. The hidden layer includes five nodes. The output layer is used for outputting computation results as a nutrition state result II. The data dissemination module is used for receiving the output nutrition state results of the result optimization module and disseminating. The intelligent distinguishing system can realize fast accurate and intelligent distinguishing of the nutritional status of the lakes and reservoirs.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and resource comprehensive utilization, and relates to an intelligent discrimination method and device for the nutritional status of lakes and reservoirs. Background technique [0002] Poor water exchange in lakes and reservoirs makes it easy to suffer from excessive nutrient salts to form eutrophication, which in turn induces excessive algal blooms and causes algal blooms. The eutrophication of lakes and reservoirs in the world has exceeded 50%. Most of the lakes and reservoirs in the Yangtze River Basin, Yunnan-Guizhou Plateau, Northeast China and Mongolia-Xinjiang region have reached eutrophication or are about to become eutrophic, causing incalculable economic losses. Maintaining the healthy water environment of lakes and reservoirs has become one of the core issues of sustainable social and economic development. Only by quantitatively, accurately and quickly judging the nutri...
