Relationship between Water Body Flow Velocity and SPI Value of Different Pollution Types
ZHANG Shiliang;Fushun Investment Audit Center;
In the paper,Liaoning Fushun urban river way is adopted as the research object,water body pollution types are divided into hybrid type,nutrition leading type and inorganic leading type according to different water particular pollutants in order to study the inner relationship between water flow velocity and SPI value of different pollution types in urban landscape water body as well as influencing factors thereof. Partial correlation analysis and correlation analysis methods are used to explore the effect mechanism of water flow velocities with different pollution types to water bodies. The study indicates that the flow velocity mainly acts through the SPI value of water inorganic suspended solid contents and algae on water bodies,and the study provides scientific basis for urban landscape water appearance pollution control.
