Embodiment 1

[0017] Embodiment 1: A kind of method for constructing ecological protection forest in water source area for the prevention and control of non-point source pollution

[0018] 1) Plant configuration: choose suitable tree species for local growth according to local conditions, and rationally match evergreen tree species and water-resistant wet broad-leaved forest species according to the characteristics of seasonal changes of tree species for forest stand tree species allocation. Better ecological landscape effect. Among them, the water-tolerant wet broad-leaved forest species are deciduous tree species, and the evergreen tree species include evergreen economic tree species and evergreen shrub species. Configure evergreen shrub species. The tree species configuration is as follows: the evergreen economic tree species are Chinese torreya, Zhejiang nan, Schima superba, Southern jujube, camphor, privet, cedar, red fennel, moso bamboo, red bamboo; the evergreen shrub species are ho...

Abstract

The invention discloses a water source area ecological protection forest constructing method for non-point source pollution prevention and treatment, and belongs to the technical field of non-point source pollution prevention and treatment and ecological engineering. The method includes the following steps of configuring plants and conducting afforestation and management, wherein tree species suitable for local growth are selected according to circumstances, evergreen species and water-tolerant wet broad-leaved forest species are reasonably matched for forest stand tree species configuration according to the tree species season-phase change characteristics, the forest ecology protection function of a water source area is realized, a good ecological landscape effect is created, the water-tolerant wet broad-leaved forest species is deciduous tree species, and the forest stand tree species configuration rule includes that evergreen economical tree species is configured between water-tolerant wet broad-leaved forests and evergreen shrub tree species is configured on the lower layer of the water-tolerant wet broad-leaved forests. The water source area ecological protection forest constructing method for non-point source pollution prevention and treatment is reasonable in design; by constructing the water source area ecological protection forest through the method, the biological diversity can be easily maintained, the ecological functions of water and soil conservation, water conservation and the like are improved, and the water source area non-point source pollution is effectively prevented.

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...
