Ratio of dominant dust retaining plants in waste dump of desert open-pit coal mine based on CATS model

doi: 10.11833/j.issn.2095-0756.20210604

Abstract:   Objective  The dump of open-pit mine in arid desert regionis easy to produces and (powder) dust and cause air pollution. The purpose of this study is to obtain the ratio of dominant dust retaining plants and species in the restoration community based on the simulation of Community Assembly by Trait Selection (CATS) model, and put forward the vegetation restoration strategy.  Method  A quadrat survey was conducted around the waste dump of Wuhai Xinxing Coal Mine in Inner Mongolia Autonomous Regionin August 2020 to determine the trait values at species and community levels, calculate the target values of functional traits, and substitute the dust retention function and root volume of plants into the model as two factors.  Result  The root volume of plant species was inversely proportional to the dust retention per unit leaf area. The root volume and soil water content was U-shaped. The simulation results showed that the highest relative abundance of each species was Salsola collina and Peganum harmala, with amedian of 0.41 and 0.32, respectively.   Conclusion  To plant S. collina and P. harmala in the dumping site with the relative abundance ratio of 6 to 4 is beneficial to dust detention, which can also explain some mechanical problems in vegetation restoration and provide reference for other studies.[Ch, 2 fig. 1 tab. 40 ref.]
