Study on non-point pollution characteristics of urban runoff in Fuzhou city

With the rapid urbanization, while point source pollution is of control, urban non-point source pollution turns into a serious threat to urban watershed.

To calculate average perennial load of non point source pollution, a direct measurement method is developed.

The occurrence of non point source pollution, is not only related to its sources, landscape pattern, but also dependents on the factors such as soil erosion, rainfall, irrigation, surface and underground run off.

In order to work out a minimum fertilizer application rate for both keeping conventional yield and reducing nutrient loading of non point source pollution, an experiment of formulated fertilization scheme on rice at different rates and.
