Embodiment Construction

[0059] Following example further illustrates the present invention, but should not be as the limitation of the present invention:

[0060] In order to verify the evaluation method, the water environment quality monitoring results of Huotongxi and Jiulong River estuaries in 2013 were selected for evaluation. The estuary of Huotong River is located in Badu Town, Ningde City, which mainly discharges domestic and agricultural sewage to the sea; the estuary of Jiulong River is located in Shima Town and Fugong Town, Longhai City, Zhangzhou, and mainly discharges agricultural and industrial sewage to the sea , Domestic sewage.

[0061] According to the technical scheme of the present invention, the water environment quality monitoring conditions of the above-mentioned 2 river estuaries are evaluated respectively. The specific evaluation and verification process is described as follows:

[0062] (1) The evaluation results of water environment quality at the estuary of Huotong Creek ...

Abstract

The invention discloses an evaluation method based on river estuary water environment quality. The evaluation method comprises two steps of river estuary water environment quality monitoring and riverestuary water environment quality evaluation. The specific method for evaluating the river estuary water environment quality comprises steps of calculating pollution indexes of evaluation factors, calculating water quality comprehensive evaluation indexes of all stations or evaluation units, judging the actual water quality types of all the stations, calculating the proportion of a certain type of water quality stations and judging the river estuary water environment quality condition. The method is advantaged in that the method is simple and easy to implement and is directly and tightly combined with the requirements of marine function division and marine environment protection planning, so the evaluation result has advantages of accuracy, objectivity, high operability and the like, anda scientific basis can be provided for decision makers to fully and objectively master the actual condition of the marine environment and realize marine environment protection and management; coastaleconomic development and the surrounding environment quality improvement are further promoted.

Description

technical field [0001] The present invention relates to the field of technical methods for monitoring and evaluating the water environment quality of river estuaries, and specifically relates to a multi-factor comprehensive water quality evaluation method for comprehensively integrating data of water environment elements in estuaries, combined with comprehensive evaluation categories, and a method for judging the water environment quality of estuaries. Finally, the evaluation method for the water environment quality of river estuaries will be realized. Background technique [0002] River estuaries are the main way for terrestrial substances to enter the ocean. The runoff of river basins brings a large amount of suspended sediment, rich dissolved nutrients and pollutants into the ocean, causing damage to river estuaries and bays. [0003] There are 11 major rivers in Fujian Province, including Beixi, Jiaoxi, Huotongxi, Aojiang, Minjiang, Longjiang, Mulanxi, Jinjiang, Jiulongj...
