Embodiment 1

[0060] This example takes the temporal and spatial analysis of runoff pollution sources in the Shishili River Basin in 2016 as the research object.

[0061] The Shishili River is an important urban landscape river in the urban area of ​​Hefei. It is located in the southwest suburb of Hefei City. It flows from northwest to southeast into Chaohu Lake. In addition to the rainwater catchment area transferred by Tangxi River, the total area of ​​the basin is 135.8km 2 , the total length of the river is about 22.9km, and it is one of the main flood passages in the southwest of Hefei. There is no mining in this watershed, no drainage of paddy fields, and rural farming is almost completely banned. The runoff pollution in the watershed mainly comes from rainfall runoff.

[0062] (1) Design the formula for calculating the total load of pollutants in rainfall runoff

[0063] According to the pre-investigation of the Shishili River, the runoff production of each land use type in the wate...

Description

technical field [0001] The invention belongs to the field of pollution load measurement and calculation, and more specifically relates to a rainwater runoff pollution load measurement method based on remote sensing interpretation and rainfall experiment. Background technique [0002] The quality of my country's surface water environment is gradually improving, but the phenomenon of black and odorous water bodies in cities is still prominent, which not only damages the urban living environment, but also seriously affects the image of the city. Urban black and odorous water remediation work can be carried out from two perspectives: point source pollution and non-point source pollution. Relatively speaking, the investigation and accounting of point source pollution is relatively simple and easy to control. After several years of treatment, it has achieved fruitful results. However, non-point source pollution has a wide range of sources and complex components. An important caus...
