Embodiment 1

[0024] This embodiment 1 is implemented under the following conditions of implementation and technical requirements:

[0025] 1. The total width of the near-natural plant community on the river bank in Shanghai Nanhui is 18m, divided into horizontal structure and vertical structure.

[0026] 2. The horizontal structure is divided into three parts. The strip-shaped planting area with a total width of 18m is divided into three equal parts along the direction parallel to the bank to obtain three strip-shaped areas near the river, in the middle, and away from the river, with a width of 6m. The vertical structure is divided into upper, middle and lower floors.

[0027] 3. The upper layer is the arbor layer.

[0028] Among them, water and wet deciduous trees and water and wet evergreen trees are planted at intervals near the river. The planting length of deciduous trees is 8m, and the planting length of evergreen trees is 4m. DBH 12-14cm, canopy closure 55-65%. The deciduous tree...

Embodiment 2

[0037] This embodiment 2 is implemented under the following conditions of implementation and technical requirements:

[0038] 1. The total width of the near-natural plant community on the river bank in Qingpu, Shanghai is 15m, divided into horizontal structure and vertical structure.

[0039] 2. The horizontal structure is divided into three parts, and the strip-shaped planting area with a total width of 15m is divided into three equal parts along the direction parallel to the bank to obtain three strip-shaped areas near the river, in the middle, and far away from the river, with a width of 5m. The vertical structure is divided into upper, middle and lower floors.

[0040] 3. The upper layer is the arbor layer.

[0041]Among them, water and wet deciduous trees and water and wet evergreen trees are planted at intervals near the river. The planting length of deciduous trees is 8m, and the planting length of evergreen trees is 4m. DBH 13-15cm, canopy closure 60-70%. The decidu...

Embodiment 3

[0050] Present embodiment 3 is implemented under the following conditions of implementation and technical requirements:

[0051] 1. The total width of the near-natural plant community on the river bank in Minhang, Shanghai is 16.5m, divided into horizontal structure and vertical structure.

[0052] 2. The horizontal structure is divided into three parts. The strip-shaped planting area with a total width of 16.5m is divided into three equal parts along the direction parallel to the bank to obtain three strip-shaped areas near the river, in the middle, and away from the river, with a width of 5.5m. The vertical structure is divided into upper, middle and lower floors.

[0053] 3. The upper layer is the arbor layer.

[0054] Among them, water and wet deciduous trees and water and wet evergreen trees are planted at intervals near the river. The planting length of deciduous trees is 8m, and the planting length of evergreen trees is 4m. DBH 12-15cm, canopy closure 50-70%. The dec...

Abstract

The invention discloses a method for constructing a near-nature plant community for preventing and controlling non-point source pollution, belonging to the technical field of plant planting. The plant community constructed by the method disclosed by the invention is located on the bank of a riverway, is belt-shaped and15-18m wide and comprises a horizontal structure and a vertical structure, wherein the horizontal structure consists of three belt-shaped areas, namely a near-riverway area, a middle area and a far-riverway area; and the vertical structure comprises upper, middle and lower layers which are formed by planting various humidity-tolerance mesic arbors, shrubs and herbaceous plants in a compounding and intercropping manner, the upper layer is an arborous layer, the middle layer is a shrub layer and the lower layer is a herbaceous layer. Through a reasonable plant space distribution and allocation method, direct runoff time can be increased effectively, the processes of pollutant infiltration, interception, absorption and the like can be promoted, and non-point source pollution can be prevented and controlled effectively; moreover, the constructed near-nature plant community can effectively create ecological benefit and has excellent function of landscape aesthetics.

Description

Technical field [0001] The present invention involves a method of plant planting technology, which is specifically a method to build a river bank with polluting the pollution of the surface source. Background technique [0002] With the increase of population and the acceleration of urbanization, the emissions of a large number of industrial, agricultural and domestic sewage have caused rivers and lakes to worsen.Water pollution is generally divided into two types: point source pollution and surface source pollution; with the effective control of point source pollution, facial source pollution has become the most important source of water pollution pollution such as rivers, lakes, etc.The highest and most distributed.Pollutants such as fertilizers, pesticides, sediment, and nutritional salt in farmland. During the process of precipitation or irrigation, they enter the water body through the field runoff of the farmland.The proportion of hard grounds and lower pads is very high. S...
