Coastal zone pollutant load estimation method

Abstract

The invention belongs to the coastal zone ecological environment evaluation field, and especially relates to a coastal zone pollutant load estimation method comprising the following steps: 1, determining a pollution source and main pollutants, and determining a point source pollution source and a non-point source pollution source according to research area pollutant formation characteristics and data obtainable conditions; determining main pollutants according to statistics of the pollutant content; wherein the point source pollution comprises industrial wastewater; wherein the non-point source pollution refers to water body pollution caused by the fact that various pollutants converge into a receiving water body under the action of large-area rainfall and runoff scouring; 2, estimating pollution load, including point source pollution load estimation and non-point source pollution source load estimation; main pollutants being total nitrogen, total phosphorus, chemical oxygen demand andammonia nitrogen. The method has the beneficial effects that main factors related to the pollutant load in the coastal zone range are generalized, a complete coastal zone pollutant load estimation system is established, and the current situation of the pollutant load level in the coastal zone range is analyzed.

Description

technical field [0001] The invention relates to the field of ecological environment evaluation and utilization in coastal zones, in particular to a method for estimating pollutant loads in coastal zones. Background technique [0002] Assessing the status quo of the ecological environment of the coastal zone and constructing a framework for assessing the ecological environment of the coastal zone are of great scientific significance for the protection of the ecological environment, the rational development of natural resources, and the coordinated development of the coastal zone's environment and economy. For the study of ecological environment evaluation, Fang and Lin have done research on the degree of ecological environment protection in the process of urbanization in China; Deng Zongcheng et al. have used the principal factor analysis method to select evaluation indicators, and have done research on the carrying capacity of the marine ecological environment in Qingdao; Guo...

AI Technical Summary

Problems solved by technology

[0004] However, there are many main factors related to pollutant load in the coastal area, and there is a lack of a complete evaluation system for pollutant load, so it is impossible to analyze the current status of pollutant load in the Bohai New Area.
