What impact will tourism activities have on water bodies in farm eco-tourism areas?

(1) The tourism industry has a considerable demand for water, which puts great pressure on regional water resources. In order to meet tourists' demand for water, farm eco-tourism resorts often adopt water supply projects such as building reservoirs, barrages, and underground reservoirs to capture atmospheric precipitation, surface runoff, and underground diving.

(2) Changes in the spatial and temporal distribution of surface water and groundwater have broken the long-term water cycle, causing the flow of springs and streams to decrease, or even dry up and disappear.

(3) On the one hand, the self-purification ability of water bodies is reduced. Some water bodies look as clear as a mirror, but in fact they are seriously contaminated by E. coli and organic matter. On the other hand, due to changes in water conditions, the original wet environment will gradually transform into a dry environment. The populations of aquatic organisms, hygrophytes, wetland waterbirds, etc. will decrease or disappear, and lower plants such as mosses on the riverbed will be difficult to sustain.

(4) Intensive tourist activities and engineering construction reshape the surface contours, exacerbating the degree of soil erosion, causing a large amount of soil components to be washed into water bodies, and the sediment content of runoff greatly increases, especially in the rainy season. , the originally clear stream became turbid.
