Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art, to provide a method for configuring shrub and grass planting bags under near-natural restoration in the northern sandy area, and to solve the problem of how to make the plant species composition and community configured in the restoration process of the existing northern sandy area. The structure is similar to natural vegetation, and with the succession of vegetation, it gradually achieves the effect of near-natural restoration

Embodiment 1

[0037] The present embodiment relates to a method for configuring a shrub-grass planting bag under near-natural restoration in a northern sandy area, and the specific steps include:

[0038] S1. Collect the survey data, analyze the site conditions of the local sandy land (desert) and desertified grassland and the ecological characteristics of the main natural vegetation types in combination with the sample plot and quadratic survey, so as to provide the basis for the determination of the species composition of the shrub and grass planting package; the main investigation content include:

[0039] ① Regional climate characteristics: precipitation, frost-free period, accumulated temperature, etc.;

[0040] ②Site characteristic parameters: topography, landform, soil type and physical and chemical properties, etc.;

[0041] ③ Community botanical characteristic parameters: species composition, community structure and height, coverage, density of different plants, etc.;

[0042] Th...

Embodiment 2

[0065] This example is an application test of the method for configuring the shrub and grass planting bag under the near-natural restoration in the northern sandy area described in Example 1. The test is mainly carried out in the Naritusumu and Wulagai management areas of the Zhenglan Banner, Xilin Gol League.

[0066] 1. Selection of shrub and grass planting bags in the Wulagai experimental area

[0067] 1.1 Experimental Design

[0068] After using the method of Example 1 to investigate and analyze the natural vegetation in the Wulagai community, the Wulagai community set up 4 combinations of shrub and grass planting packages (as shown in Table 1) for the composition of 4 kinds of natural grassland vegetation, and each combination was repeated 3 times. The size of the cell is 5*5m 2 , The plot was planted on July 5, 2019, with a seeding rate of 3.0kg / mu. In August 2019, a preliminary survey and statistics of the community have been carried out. Vegetation survey (monthly f...

Abstract

The invention belongs to the technical field of plant planting, and relates to a shrub and grass planting bag configuration method under near-natural recovery in northern desert areas, which specifically comprises the following steps: S1, collecting survey data; s2, determining species composition of a shrub and grass planting bag; s3, planting test and effect evaluation: investigating vegetation species composition recovered by the shrub and grass planting bags, comparing community structure indexes with natural vegetation indexes, and carrying out similarity analysis and plant species composition and dominant species analysis, and S4, product optimization and shaping; through a more scientific shrub and grass planting bag configuration method, the recovered vegetation is more similar to natural vegetation in the aspects of category composition, community structure and the like, and the stability of an ecological system is more perfect; according to the method, main dominant species and associated species in the natural vegetation are more scientifically matched, the proportion of different plant species in the shrub and grass planting bag is configured, and a foundation is laid for gradual forward succession of the recovered vegetation to the natural vegetation.

Description

Technical field: [0001] The invention belongs to the technical field of plant planting, and relates to a method for configuring a shrub grass planting bag under near-natural restoration in a northern sandy area. Background technique: [0002] The grassland area in northern my country is about 1.6 million square kilometers, and grass animal husbandry production is the most important grassland utilization method in the northern region. High-intensity utilization leads to the degradation of plant communities, the expansion of desertification, and even the loss of some ecosystem services. Although, with the support of a series of national ecological conservation projects, the ecological environment in this area has been significantly improved. However, the region still faces severe environmental pressures due to human activities and global climate change. [0003] As one of the most vulnerable areas in my country, it has a very important strategic position in the construction ...
