Problems solved by technology

However, since the change of lake water quality is a cumulative process, it has a cumulative lag effect on meteorological factors, and the time scales of responses of different water quality elements to meteorological factors are different. The selection of meteorological factors by traditional analysis methods has limitations. It is not the optimal meteorological factor affecting the water quality of lakes, and the conclusions obtained are limited

Embodiment Construction

[0069] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0070] Step (5), example description:

[0071] In order to further illustrate the advantages of the present invention, taking the water quality of Erhai Lake, a plateau lake in Dali City, Yunnan Province, and the observation data of Dali Meteorological Station closest to Erhai Lake as examples, the method for constructing and screening the optimal meteorological factors affecting lake water quality is briefly described.

[0072] Step (5.1), data

[0073] The water quality elements use the monthly water quality element data monitored by the Dali Bai Autonomous Prefecture Environmental Monitoring Station from January 2008 to March 2018, including total phosphorus, chemical oxygen demand, dissolved oxygen, permanganate index, five-day biochemical oxygen demand, Algae count, total nitrogen, ammonia nitrogen, transparency, dissolved oxygen saturation rate, chloro...

Abstract

The invention discloses a method for constructing and screening optimal meteorological factors influencing lake water quality. The method is different from the traditional technical thought and methodthat the related coefficients of the screened meteorological factors influencing the lake water quality are low. According to the invention, the meteorological factor sequence is reconstructed; the optimal meteorological factors influencing the lake water quality are screened, the response and lag characteristics of the lake water quality to the meteorological factors are objectively reflected, ascientific basis is provided for lake water quality ecological evaluation research and water quality factor prediction, the application prospect is wide, and meanwhile huge social and economic benefits can be generated.

Description

technical field [0001] The invention belongs to the field of ecological environment protection research and forecasting, and in particular relates to a method for constructing and screening optimal meteorological factors affecting lake water quality. Background technique [0002] The ecological environment is the basic condition for human survival, closely related to human activities, and affects human survival and development. A good ecological environment is the fairest public product and the basis for human survival and health, as well as the existence and development of civilization. Due to natural, historical, man-made and other reasons, as well as the irrational use and over-exploitation of natural resources, the ecological environment has been destroyed, and the pollution of water resources has become increasingly serious. Human health restricts the sustainable development of economy and society. [0003] The construction of ecological civilization is closely relate...
