Embodiment 1
[0036] The structure of collecting soil on the surface when wind and sand occurs in the present invention mainly includes an upper part 1 and a lower part 2, wherein the upper part 1 is composed of a grid part 1-1 and a fixed part 1-2, and the lower part 2 is composed of a uniform sprinkler. The pile of weeds or straw 2-1 is composed, and the thickness of the pile is controlled between 2-6cm. More specifically, the size of the mesh 1-1-1 of the grid part 1-1 is smaller than that of the weeds or straw 2-1. length. The mesh part 1-1 is a nylon mesh. The fixing part 1-2 is an iron nail.
Embodiment 2
[0038] The research area is located in Xinbaolige Gacha, Sunid Right Banner, Inner Mongolia, with geographic coordinates of 42°59′N, 112°45′E. It belongs to an arid continental climate, with an annual average temperature of 5.0°C and an average annual precipitation of 181.9mm. The temperature changes drastically and the temperature difference is large. The winter is long and cold, and the summer is relatively hot. The precipitation is less and unevenly distributed. The sunshine time is long and the light energy is sufficient. The annual number of windy days is 59.6, and the annual number of sandstorm outbreak days is 12.1 on average. It is the best wind energy area in China and one of the areas with frequent sandstorms. The vegetation type is temperate desert grassland, the grassland is severely degraded, the surface is gravel, the plants are sparse, and the coverage is ≤5%.
[0039] The selected plot is relatively flat, covering an area of 9200m 2 (Plot 1), adopt net fenc...
Embodiment 3
[0043] The location of the study area is the same as Example 2, and sample plot 2 is set on the northwest side of it, with an area of 9000m 2 , take net fence protection. Randomly set 10 pieces of 20×20m 2 For the plots, 5 were set as controls, and the other 5 were covered with grass nets; the thickness was controlled between 2-2.5 cm, and then covered with grid-shaped nylon nets. Similarly, five measuring rulers made of steel rulers with a length of 10 cm were vertically arranged at equal distances along the diagonal direction in each plot to measure the thickness of the accumulated soil.
[0044] In December 2011, 5 communities were selected for the implementation of the grass-covering net project, and the accumulation of surface soil and seed resources was completed by using the sandstorm in winter and spring. Vegetation characteristics survey was carried out in mid-August 2012, and five 1×1m 2 Sample plots were used to measure vegetation density and aboveground biomas...
