Ecological protective forest belt structure on periphery of urban agglomeration

Abstract

The invention relates to an ecological protective forest belt structure on the periphery of an urban agglomeration. The structure comprises protective forest belts arranged on the periphery of a beltway or at the junctions between cities and countryside, wherein the protective forest belts between the adjacent cities are connected; each protective forest belt comprises a deceleration diversion forest belt, a vortex purification forest belt and a dense protective landscape forest belt which are sequentially arranged in the wind direction; a shrub and grass interval area is arranged between each vortex purification forest belt and the corresponding dense protective landscape forest belt, and each deceleration diversion forest belt is a pure arbor forest belt. Each vortex purification forest belt comprises arbor planted along rings, large-crown-breadth arbor planted in the centers of the rings, shrubs and herbaceous ground cover plants, and each dense protective landscape forest belt comprises shrubs, herbaceous ground cover plants and rows of arbor, wherein every two adjacent rows of arbor are planted triangularly. According to the structure, by arranging the forest belts with different functions and structures, incoming wind gradually and orderly passes through all the functional forest belts, and the effects of guiding the wind direction, reducing the wind speed and removing remaining dust are finally achieved.

Description

technical field [0001] The invention relates to the fields of ecological environment management and garden construction, in particular to an ecological protection forest belt structure on the periphery of urban agglomerations. Background technique [0002] In recent years, my country's urbanization process has accelerated, and the scale and number of cities have gradually increased. At the same time, a number of super-large urban agglomerations have emerged. With the development of the city, various environmental problems such as air pollution, water pollution, heat island effect, and noise pollution in the city have become increasingly prominent, seriously affecting the physical and mental health of urban residents and their daily work and life, and also restricting the quality of urban environment in my country. modernization. [0003] As an urban ecological barrier, urban shelterbelts can play the role of defending against sandstorms, guiding wind direction, purifying air...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems such as relatively single plant species, unreasonable initial planting density and unreasonable forest layer structure in the current urban shelterbelts, which lead to the problems that the actual benefits of the shelterbelts are not good enough, and the actual benefits are seriously lower than expected. The ecological protection forest belt structure on the periphery of the urban agglomeration, by setting forest belts with different functions and structures, makes the incoming wind pass through each functional forest belt gradually and orderly, and finally achieves the purpose of diverting wind direction, reducing wind speed, and purifying dust
