Abstract

Purpose

Herbaceous plants could be an effective measure for soil bioengineering to strengthen the surface soil of the dump. Before the herbaceous plants are planted, selecting suitable herbaceous plants can improve the root reinforcement, and at the same time, it can also ensure long-term soil stability.

Methods

Firstly, a 20 × 20 m rectangular area is selected as the study site and is divided into 16 rectangular areas, each of which has a size of 5 × 5 m. In the center of each 5 × 5 m rectangular area, a 1 m × 1 m rectangular area was selected as the sampling point to investigate the growth characteristics of herbaceous plants. Secondly, the TOPSIS method of introducing weights and Wu-Waldron model are used to calculate the effective root reinforcement of herbaceous plants. Finally, by comparing the value of effective root reinforcement, herbaceous plants suitable for root reinforcement were selected.

Results

The results of the study showed that Plantago depressa has the highest weight in the study site, with a weight value of 0.1971. The root area ratio and root reinforcement of the herbaceous plants decreased with the increase of soil profile depth. By comparing the average value of effective root reinforcement at different depths, the suitable herbaceous plants identified are Artemisia sieversiana, Alopecurus aequalis and Leonurus japonicus.

Conclusions

This study provides a method to select the herbaceous plant species that reinforce the soil in the dump. This method can be applied not only in the dump but also in other areas.
