Background
At present, due to the influence of global climate change and excessive grazing, the phenomena of grassland degradation or desertification frequently occur, the degradation area is increasingly enlarged, the grassland vegetation disappears to form patch-shaped sandy land, and the further development can form large-area degradation sandy land. Therefore, the method is an effective way for controlling the desertification of the grassland by controlling the continuous development of the small-area patch-shaped sandy land. The degraded grassland of mountain areas and plains around large and medium-sized cities is becoming a sand source land for sand-dust weather and sand storm, which can obviously reduce the environmental quality of the life of residents and cause serious loss of national economic development. Rainfall in summer and snowfall in winter in northern grasslands play a decisive role in the growth of vegetation in grasslands. However, northern grasslands have flat topography, stable wind direction and few shelters, and snowfall is difficult to persist on patch sand land degraded by the grasslands in winter through the action of wind power. Due to the reduction of vegetation coverage, the soil water is difficult to effectively survive under the evaporation action of rainfall in summer due to the lack of plant root system conservation.

The plant fiber net can intercept wind blowing snow in winter, grass seeds and sand substances in wind and sand flow and make the grass seeds and the sand substances fall in the grid 4. Because the covering of graticule mesh 4, can effectively reduce the temperature of sand face, increase the roughness of sand face, simultaneously, absorb and condense partly precipitation and the moisture in the air, impel the grass seed in the graticule mesh 4 to sprout naturally to reach the mesh of restoreing plaque sand 1.
In a preferred embodiment of the present application, the height of the soil heap windbreak is directly proportional to the depth of the trench 2. Specifically, the deeper the trench 2 is, the higher the height of the soil heap wind-blocking wall is, and the higher the height of the soil heap wind-blocking wall is, the better the wind-blocking effect is achieved, so that the inner area of the boundary of the patch sand 1 can be better protected, the air quantity is reduced, the wind speed is reduced, grass seeds and rain and snow are prevented from being blown away, and the purpose of continuous storage of rain and snow is achieved.
In summary, by digging a trench 2 along the boundary of the patch sand land 1 and towards one side edge of the main wind direction, stacking the excavated earth on one side of the main wind direction to form a soil heap wind shield, and planting shrubs 3 at the bottom of the trench 2 along one side edge of the main wind direction, under the action of the soil heap wind shield and the shrubs 3, the grid 4 covering the inner surface of the boundary of the patch sand land 1 can be protected, so as to prevent the grid 4 from being blown away by wind or buried in the sand, and by additionally arranging the grid 4, the earth surface sand substances and the seeds of partial herbaceous plants can be fixed and activated in the grid 4. In summer, the seeds can be promoted to germinate through the ecological residual water continuously stored in the grid 4. In winter, the shrubs 3 can be used for reducing the wind speed and stopping wind and blowing snow, so that the snow can be continuously stored in the grid 4, the growth of herbaceous plants in the grid 4 is further promoted, the purpose of preventing and treating water and soil loss is achieved, and the patch sand 1 can be restored, so that the grassland can be quickly formed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
