Embodiment 1

[0049] Site selection: Slope 1 of Nangou Watershed, Ansai County, Shaanxi Province.

[0050] A slope vegetation configuration method suitable for the loess hilly area. First, the selected slope is graded, and the slope is divided into a flat slope with a slope of 0-10°, a gentle slope with a slope of 10-20°, and a slope of 20-30°. ° slopes, steep slopes with a gradient of 30-40° and steep slopes with a gradient of >40°;

[0051] After the slope is graded, the slope position is graded, and the slope is divided into three parts: the upper slope, the middle slope and the downward slope according to the length, and each part accounts for 1 / 3 of the whole slope length; 1 / 2 of the slope length is the middle and upper slope position, and below the middle of the slope, accounting for 1 / 2 of the whole slope length is the middle and lower slope position.

[0052] After the slope and the slope position are classified, the vegetation configuration is then carried out, and the steps are a...

Embodiment 2

[0090] Site selection: Slope 2 of Nangou Watershed, Ansai County, Shaanxi.

[0091] The grades of grade and grade are the same as in Example 1.

[0092] A method for configuring slope vegetation suitable for loess hilly area, the steps of which are:

[0093] 1. Plant configuration

[0094] (1) Measurement of the site conditions of the slope surface: First, use the compass to measure the slope of the vegetation construction slope, measure the length of the slope, and delineate the boundary of the slope position.

[0095] After measurement, the actual slope of the slope in this example is 15°, which is a gentle slope with a slope length of 150m and a semi-sunny slope. The original vegetation on the slope is secondary natural grassland with S. Cinnamon is a companion species.

[0096] According to the slope length and slope conditions, the upper slope position (above the middle of the slope surface, accounting for 1 / 3 of the slope length, and the length is 50m) is used to buil...

Embodiment 3

[0124] Site selection: Slope 3 of Nangou Watershed, Ansai County, Shaanxi Province.

[0125] The grades of grade and grade are the same as in Example 1.

[0126] A method for configuring slope vegetation suitable for loess hilly area, the steps of which are:

[0127] 1. Plant configuration

[0128] (1) Measurement of the site conditions of the slope surface: First, use the compass to measure the slope of the vegetation construction slope, measure the length of the slope, and delineate the boundary of the slope position.

[0129] After measurement, the actual slope of the slope in this example is 37°, which is a steep slope, with a slope length of 78m and a semi-sunny slope. The original vegetation on the slope surface is secondary natural grassland with S. Cinnamon is a companion species.

[0130] According to the length of the slope, the upper and middle slopes (upper and middle of the slope, accounting for 2 / 3 of the slope length in total, 52m in length) were used to plan...

Abstract

The invention discloses a slope vegetation configuration method suitable for loess hilly areas, belonging to the technical field of ecological restoration engineering. Plant herbs on the slope, shrubs on the middle slope, and trees on the down slope; herbs on the upper slope of the slope site, shrubs and trees on the middle and lower slope, and trees on the bottom of the slope; Plant herbs on the upper and middle slopes of the site, shrubs and trees on the downslope, and trees at the bottom of the slope. The purpose of the present invention is to provide a slope vegetation configuration method suitable for the loess hilly area, by configuring different plants and fish scale pits to solve the problems of soil erosion, sparse vegetation on slopes, and low soil nutrients in the loess hilly area of ​​my country, so as to improve vegetation The sustainability of construction, the purpose of ecological restoration.

Description

technical field [0001] The field belongs to the technical field of ecological restoration engineering in loess hilly areas, and particularly relates to a slope vegetation configuration method suitable for loess hilly areas. Background technique [0002] The loess hilly area is characterized by vertical and horizontal gullies, broken terrain, extensive distribution of Liangmao slopes, loose and erodible topsoil structure, serious soil erosion and soil degradation. While soil erosion takes away a large amount of runoff and sediment, a large amount of soil nitrogen and phosphorus and other nutrients are also lost. Vegetation restoration can conserve water sources, improve soil quality, and increase surface coverage to prevent soil erosion, which in turn will preserve soil salinity. [0003] At present, the compound vegetation construction method implemented in the loess hilly area mainly adopts the mixed forest of arbor and irrigation, and the unified fish scale pit is used fo...
