Problems solved by technology

However, in the previous vegetation restoration process, most of them only considered the restoration status of biodiversity index and vegetation coverage, but seldom considered the impact of species structure changes, so it is very unfavorable for vegetation restoration of ecosystem functions
At present, there is no published evaluation method of vegetation restoration effect based on plant species structure.

Embodiment Construction

[0008] The present invention will be described in further detail below, but not as a limitation of the present invention.

[0009] Step 1: Near the target sample plot of vegetation restoration, select a non-degraded vegetation sample plot with the same geographical and climatic conditions as a control sample plot.

[0010] Step 2: Take a sample plot in the control plot (arbor sample plot 10m×10m, shrub forest 2m×3m, herb 1m×1m) to investigate vegetation parameters, including the species name, number of plants and coverage of each herbaceous and shrub species , average height, species name, diameter at breast height, crown width, and plant height of each tree plant.

[0011] Step 3: Calculate the plant species structure of the plot vegetation (including diversity index, richness index, flora structure index, source structure index, group structure index, dominant species structure index) based on the survey data of the control plot.

[0012] 1) Calculate the Simpson diversity ...

Abstract

The invention relates to a vegetation restoration effect evaluation method based on a plant species structure. The plant species structure comprises the variety index, the richness index, the flora structure index, the source structure index, the plex structure index and the dominant species structure index. According to the vegetation restoration effect evaluation method based on the plant species structure, a contrast sample land is arranged, a quadrat survey is conducted so that data can be obtained, the plant species structure of a vegetation restoration sample land and the plant species structure of the contrast sample land are compared, and the vegetation coverage of the vegetation restoration sample land and the vegetation coverage of the contrast sample land are compared, and the vegetation restoration effect is evaluated according to difference values. The vegetation restoration effect evaluation method based on the plant species structure has the advantages that the restoration effect of plant species constitutes can be specifically and fully compared; the main problem, existing after vegetation restoration, of the plant species structure can be visually reflected.

Description

technical field [0001] The invention relates to a vegetation restoration effect evaluation method based on plant species structure, belonging to the technical field of ecological restoration. Background technique [0002] Vegetation restoration is relative to vegetation destruction, and its main purpose is to restore or rebuild destroyed or damaged vegetation and restore its ecosystem functions. Therefore, increasing the coverage rate of vegetation to the original level and making the plant species structure reach the original composition characteristics as far as possible are the two main tasks of vegetation restoration. Therefore, the restoration status of plant species structure and vegetation coverage rate are two key indicators to evaluate the effect of vegetation restoration. [0003] Plant species structure is different from biodiversity in that it involves not only biodiversity index, but also species structure characteristics such as source structure, floristic str...
