Embodiment 1

[0049] Site selection: Slope 1 of the Nangou River Basin in Ansai County, Shaanxi Province.

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

[0051] After the slope is graded, the slope position is classified, and the slope is divided into three parts according to the length: uphill, middle and downhill. Each part accounts for 1 / 3 of the entire slope length; above the middle of the slope, it occupies the entire 1 / 2 of the slope length is the mid-upper slope position, and below the middle of the slope surface, accounting for 1 / 2 of the entire slope length is the mid-down slope position.

[0052] After the slope and slope are graded, the vegetation configuration is follow...

Embodiment 2

[0090] Site selection: Slope 2 of Nangou River Basin, Ansai County, Shaanxi Province.

[0091] Slope and slope classification are the same as in Example 1.

[0092] A slope vegetation configuration method suitable for loess hilly areas, the steps are:

[0093] 1. Plant configuration method

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

[0095] After measurement, the actual slope of the slope in this embodiment is 15°, which belongs to a gentle slope with a slope length of 150m and a semi-sunny slope. The original vegetation on the slope surface is the secondary natural grassland with the dominant community of Artemisia spp. Osmanthus osmanthus is a companion species.

[0096] According to the slope length and slope conditions, take the upslope position (above the middle of the slope, accounting for 1 / 3 of the slope l...

Embodiment 3

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

[0125] Slope and slope classification are the same as in Example 1.

[0126] A slope vegetation configuration method suitable for loess hilly areas, the steps are:

[0127] 1. Plant configuration method

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

[0129] After measurement, the actual slope of the slope in this embodiment is 37°, which belongs to a steep slope with a slope length of 78m and a semi-sunny slope. The original vegetation on the slope surface is the secondary natural grassland with the dominant community of Artemisia spp. Osmanthus osmanthus is a companion species.

[0130] According to the slope length, adopt the upslope and mid-slope positions (the upper and middle parts of the slope, accounting for 2 / 3 of the sl...

Abstract

The invention discloses a slope vegetation configuration method suitable for a loess hilly region, and belongs to the technical field of ecological restoration engineering. The method comprises the following steps: dividing a sloping field into a flat slope, a gentle slope, a slope, a steep slope and a sharp slope; grading the slope positions; planting herbaceous plants at an uphill position of the gentle slope site, planting shrubs at a middle slope position, and planting arbors at a downhill position; planting herbaceous plants at the middle-upper slope position of the slope site, planting shrubs and arbors at the middle-lower slope position, and planting arbors at the bottom of the slope; and planting herbaceous plants at the uphill position and the middle slope position of the steep slope site, planting shrubs and arbors at the downhill position respectively, and planting arbors are planted at the bottom of the slope. According to the slope vegetation configuration method suitablefor the loess hilly region, the problems of water and soil loss, sparse slope vegetation and low soil nutrient in the loess hilly region in China are solved by configuring different plants and fish-scale pits, and the purposes of improving the sustainability of vegetation construction and restoring ecology are achieved.

Description

technical field [0001] This field belongs to the technical field of ecological restoration engineering in loess hilly areas, and in particular relates to a slope vegetation configuration method suitable for loess hilly areas. Background technique [0002] The loess hilly area has vertical and horizontal ravines, broken terrain, wide distribution of Liangmao slopes, loose and erodible surface soil structure, and serious soil erosion and soil degradation. While soil erosion takes away a large amount of runoff and sediment, a large amount of soil nutrients such as nitrogen and phosphorus are also lost. Vegetation restoration can conserve water sources, improve soil quality, increase surface coverage to prevent soil erosion, and then have a conservation effect on soil salinity loss. Therefore, vegetation restoration and reconstruction are fundamental measures for soil erosion control in loess hilly areas. [0003] At present, the method of planting composite vegetation implemen...
