Problems solved by technology

Therefore, only using the above-mentioned conservation and treatment methods cannot well solve the problem of fragile ecosystems and large-scale soil erosion.
Moreover, the slope surface is exposed seriously, and due to wind erosion, water erosion, gravity erosion, etc., there is often a large area of ​​arsenic sandstone collapse, and there is no good efficient and low-cost treatment method; and the rainwater collection place in the ditch, the water flow often carries a large amount of water. Sediment flows away, but cannot form an effective inte

Embodiment 1

[0054] In Erhugougou, a small watershed in Geqiugou, Nuanshui Township, Zhungeer Banner, Ordos, the invention was tested.

[0055] In order to facilitate observation of test phenomena, observation of test data and analysis of test results, a segmented test is carried out on the entire spatial configuration mode.

[0056] (1) Vegetation collocation on the slope and establishment of interception ditch and cellar

[0057] a. Choose a gentle slope edge area for plantation of Chinese pine plantation, use mechanical digging, hole-shaped soil preparation, planting with characters, and the spacing between plants and rows is 2m×2m.

[0058] b. Excavate the interception ditch parallel to the ditch at a distance of 1.5m from the ditch edge, with a depth of 40-50cm and a width of 30-40cm. Spray W-OH with a concentration of 4-6% in the ditch to prevent water infiltration.

[0059] c. Dig cellars 4 to 8 meters away from the side of the intercepting ditch along the ditch. The depth of the ...

Abstract

The invention discloses a corrosion-resistance and growth-promotion binary three-dimensional configuration mode suitable for a pisha sandstone area typical geomorphological structure. Different treatment modes are adopted for different three-dimensional spatial positions such as a slope top, a trench slope and a trench bottom, different plants are planted in a matched mode, corresponding engineering measures are taken, and thus the good effects of solidifying pisha sandstone, promoting growth of plants, preserving soil and water and controlling soil and water losses of a pisha sandstone area are achieved. By means of the method, soil and sand can be stabilized, and meanwhile vegetation recovery of the pisha sandstone area is promoted.

Description

Technical field: [0001] The method relates to an anti-corrosion and growth-promoting binary three-dimensional configuration mode suitable for small watersheds of sandstone, and belongs to the technical field of ecological restoration in arid and desertified areas. Background technique: [0002] The arsenic sandstone belongs to a special landform structure in the Loess Plateau area, with red and white alternates, and is mainly distributed in the area centered on the border between Shanxi, Shaanxi and Mongolia. Due to the bare surface, coupled with the interaction of water erosion, wind erosion and gravity erosion, the local extremely serious soil erosion has become the main source of coarse sand in the middle reaches of the Yellow River. When there is no water, the arsenic sandstone is as hard as a rock, but when it meets water, it becomes soft and muddy in a very short time, and at the same time, it is severely eroded by wind. Because the terrain in this area is broken, the...
