A method for building ecological protection forests in water source areas for the prevention and control of non-point source pollution

Abstract

The invention discloses a method for constructing an ecological protection forest in a water source area for the prevention and control of non-point source pollution, belonging to the technical fields of non-point source pollution prevention and ecological engineering. It includes the following steps: plant configuration: select suitable tree species for local growth according to local conditions, and rationally match evergreen tree species and water-tolerant wet broad-leaved forest species for forest stand tree species configuration according to the seasonal change characteristics of tree species. , to create a better ecological landscape effect, in which the water-tolerant wet broad-leaved forest species are deciduous tree species, and the tree species allocation principle of the stand is: the water-resistant wet broad-leaved forest is equipped with evergreen economic tree species, and the lower layer of the water-resistant wet broad-leaved forest is equipped with evergreen shrub species ; Afforestation; Management. The above-mentioned method for constructing an ecological shelterbelt in a water source area for the prevention and control of non-point source pollution has a reasonable design. The construction of an ecological shelterbelt in a water source area by this method is conducive to maintaining biodiversity, improving ecological functions such as water and soil conservation and water conservation, and effectively preventing and controlling water sources. Area source pollution.

Description

technical field [0001] The invention belongs to the technical fields of prevention and control of non-point source pollution and ecological engineering, and in particular relates to a method for constructing ecological protection forests in water source areas for the prevention and control of non-point source pollution. Background technique [0002] The water source area is a natural basin that is formed naturally or artificially, collects surface water through surface runoff, and provides clean water. At present, in some areas, the land use mode in the water source area has changed, intensive management has become increasingly serious, the original vegetation has been severely damaged, and soil erosion tends to worsen, resulting in a large number of non-point source pollutants continuously entering the water body, which is harmful to the water environment and water resources. produce adverse effects. Soil erosion is an important cause of non-point source pollution in water...
