Influence of Miaozhai Reservoir on Water Cycle
The westerly belt in the mid-latitude area, the polar easterly wind in the high-latitude area, the water conservancy measures on the east coast of the mainland, the construction of reservoirs and ponds, etc. Intercept floods, increase runoff in dry season, increase evaporation due to the expansion of water surface area and the increase of groundwater level, and transfer water across basins.
Description:
Expanding irrigation area increases evaporation to some extent, and increases water vapor content and precipitation in the atmosphere. Agricultural and forestry measures, changing drought into water, intensive cultivation, closing hillsides to facilitate afforestation and afforestation can increase infiltration, regulate runoff, increase evaporation and increase precipitation to a certain extent.
Reclaiming land around the lake reduces the natural water storage capacity of the lake, weakens its flood control and drought resistance, and also weakens the regulation of the lake water body on the climate in the surrounding areas. The factors affecting underground runoff can refer to the factors affecting surface runoff and infiltration, mainly considering karst landform, because there are many underground caves and underground rivers in karst landform area, which store a lot of groundwater.
