Abstract. Understanding the effects of ecological restoration in abandoned coal mine on soil and plant is important to improve the knowledge of ecosystems evolution and facilitate taking appropriate ecological restoration management practices. This study aims to evaluate the coupling relationship between plant diversity and soil properties after ecological restoration in abandoned coal mine area. The plant diversity and soil properties were investigated in four sites of different ecological restoration patterns in Fengcheng county, a typical coal- rich area in the history of southern China. The results indicated that: 1) the PSR (Pinus massoniana and Schima superba gardn restoration) site had higher Shannon-Wiener index and Simpson index values than PR (Pinus massoniana restoration) site, and in herb layer, the plant diversity was significantly higher than other layers; 2) in the PSR site, the soil properties were improved more notably than that of PR and NR (nature restoration) sites, and the plant diversity were also better than PR site; 3) Clay, SOM (soil organic matter), and MBC (microbial biomass carbon) made a great contribution to the plant diversity. It was concluded ecological restoration patterns had significant effects on soil nutrient content and plant diversity, and there exists evident coupling relationship between plant diversity and soil properties. This study has important effects of ecological restoration and management in abandoned coal mine area.

Short summary
This study aims to evaluate the coupling relationship between plant diversity and soil properties after ecological restoration in abandoned coal mine area. The plant diversity of arbor, shrub, and herb layers, and the soil properties in different depth layers were investigated in different ecological restoration patterns. Ecological restoration patterns had significantly effect on plant diversity. There was significant differences in plant diversity and ecological restoration patterns.
