摘要:
This paper analyzes the impact of human activities on river ecosystems from two aspects of agricultural production and watershed water conservancy project construction. Among them, dambased water conservancy projects have caused runoff patterns and artificial segmentation of rivers, which has seriously damaged the energy and material of river corridors as well as the capacity of species to transport the passage. Modern agricultural production not only uses a lot of pesticides and chemical fertilizers, but also occupies a large number of terraces and floodplains, directly leading to the emergence of non-point source pollution. Sometimes the runoff characteristics of the city will also be changed, so the ecological value of the rivers in the city is seriously damaged under such circumstances.
