Background art:
the grassland area in the north of China is about 160 ten thousand square kilometers, and the grass husbandry production is the most main grassland utilization mode in the north. The high intensity of utilization leads to the degradation of plant communities, the expansion of desertification and even the loss of certain ecosystem service functions. Although, the ecological environment of the region is obviously improved under the support of a series of ecological conservation projects in China. However, this area is still under severe environmental stress due to the influence of human activities and global climate changes.
As one of the most vulnerable areas of the ecological environment in China, the ecological safety barrier has a very important strategic position in the construction of the ecological safety barrier and the economic zone in the north. In the prior art, in the treatment process of the northern sandy area, when the plants are replanted on the degraded desertification grassland to recover the grassland vegetation, although different plant species combination modes are used, the prior plant establishment and the ecological benefit establishment of the plant species in the recovery process are more considered, and the similar relation with the natural vegetation in the plant species configuration process and the similar degree after vegetation recovery are not fully considered.

The allocation proportion of the seeds of each species is determined according to the composition proportion of the natural vegetation species, the local site condition, the germination and growth condition of the seeds, the sowing mode and the like.
S3 planting test and effect evaluation
The matched shrub and grass planting bag is subjected to field sowing and planting tests, the vegetation recovery effect is investigated after 2-3 years, indexes such as vegetation type composition and community structure recovered by the shrub and grass planting bag for investigation are compared with natural vegetation indexes, similarity analysis and plant type composition and dominant species analysis are carried out, the dominant species are determined by calculating important values, the similarity analysis is used for judging the similarity of the shrub and grass planting bag for recovering the vegetation, and the important value analysis is used for judging whether the dominant species of the planting bag are the same as the dominant species of the natural vegetation. The vegetation composition and community structure are investigated by adopting a conventional ecological field investigation method, wherein a herbaceous sample is 1m multiplied by 1m for an investigation sample, and a shrub sample is 10m multiplied by 10m for the investigation sample; measuring the vegetation coverage by adopting a network cable method; the density (number of plants) is measured by a counting method; measuring the biomass on the ground, namely, uniformly separating seeds and cutting stems and leaves on the ground, weighing fresh weight, bagging, taking back to a laboratory, drying at 65 ℃ and measuring dry weight.

TABLE 7 comparison of Umbelliferae shrubbery planting bag 4 with natural grassland
The method is characterized in that a long-term process is needed to restore the desertified grassland to the grassland in the natural state by using the shrub and grass planting bags in proportion, test data of 3 years cannot represent the long-term process, and the data of the last 2021 year in 8 months are subjected to important value analysis and are compared with the original grassland important value. The important values of the planting bag 1 are that the maximum value of the wheatgrass and the Chinese wildrye is 0.24 and 0.19 respectively, and the maximum value of the alfalfa bean and the high-speed sand planting is 0.15 and 0.10 respectively, which indicates that the main dominant species are the grassy ice grass and the Chinese wildrye of the gramineae and the alfalfa bean and the high-speed sand planting of the leguminosae, and are matched with the types of the dominant species of the natural vegetation, namely the Chinese wildrye, the wheatgrass and the miscellaneous grass; the important values of the grasses such as the leymus chinensis, the wheatgrass and the like of the planting bags 2 and 4 are relatively close to those of natural grassland, the grasses are the dominant species in the community, and the planting bags 4 are leguminous, and although the leguminous is also a suboptimal plant, the planting bags 4 can substitute for the high-yield firewood and high-yield sand of the Melissitus ruthenicus. Therefore, after 3 years of restoration, the planting bags 1, 2 and 4 are closer to the vegetation composition of the natural grassland. The planting bag 3 is made of the miscellaneous grass and the salsola collina which becomes the dominant plant and is not in accordance with the composition of natural grassland plants. By contrast, the planting bag 2 is closer to the natural grassland plant composition in the 3-year ecological restoration.

The average height of the planting bag 3 is the highest and reaches 27.27cm, the average coverage of the planting bag 3 is the highest and reaches 62.67%, and the density of the planting bag 1 is the highest and reaches 42.67 plants/m2. Because the proportion of plants in each grass planting bag is different, the performance of the possible treatment effect on height, coverage and density is different.
As can be seen from table 10, the height of the planting bag 3 was significantly higher than the height of the planting bags 2 and 5(P < 0.05) in the expression of the vegetation height after restoration, and the coverage of the planting bag 3 was significantly higher than the coverage of the planting bags 2 and 5(P < 0.05) in the expression of the vegetation coverage after restoration, and the restoration effect of the shrub grass planting bag 3 was the best in terms of height and coverage. In the expression of vegetation density after restoration, planting bag 1 was significantly higher than planting bag 3(P < 0.05), possibly due to interspecies competition, resulting in a decrease in the density of planting bag 3.
