Abstract

The water transparency is an important index reflecting the water limpidity and turbidity extent. The present invention provides a method used for obtaining water transparency under current conditions and noncurrent conditions, which comprises steps of inputting data about water features, current features, boundary hydrology, water quality, and the like, into related formulas to work out suspended matter concentration, chlorophyl concentration and permanganate index concentration; and then inputting the suspended matter concentration, chlorophyl concentration and permanganate index concentration obtained into transparency prediction formulas to work out the water transparency values. The present invention is capable of used for detecting the water features under current conditions in a water environment, referring to detecting the water transparency; for calculating out the water environment or transparency improving effect for a variety of pollution controlling steps; and for working out the affecting extent on the water environment or transparency by nature factors.

Description

technical field [0001] The technical fields related to the present invention mainly include: the acquisition of the current water body characteristics (transparency) in the water environment; the calculation of the improvement effect of the water environment (transparency) under various pollution control measures; the calculation of the influence degree of the water environment (transparency) characteristics under the influence of natural factors. Background technique [0002] The transparency of water body is an important index reflecting the degree of clarity and turbidity of water body. Water transparency directly affects the growth and reproduction of aquatic plants, and is one of the factors that must be considered in the restoration and reconstruction of water ecosystems. In addition, water transparency is also an important indicator to measure the quality of water landscape characteristics and an important factor affecting the development of tourism. . [0003] At pr...
